slurm.conf(5)

NAME
slurm.conf - Slurm configuration file

DESCRIPTION
/etc/slurm.conf is an ASCII file which describes general SLURM configuration information, the nodes to be managed, information about how those nodes are grouped into partitions, and various scheduling parameters associated with those partitions. This file should be consistent across all nodes in the cluster.

The file location can be modified at system build time using the DEFAULT_SLURM_CONF parameter. In addition, you can use the SLURM_CONF environment variable to override the built-in location of this file. The SLURM daemons also allow you to override both the built-in and environment-provided location using the "-f" option on the command line.

Note the while SLURM daemons create log files and other files as needed, it treats the lack of parent directories as a fatal error. This prevents the daemons from running if critical file systems are not mounted and will minimize the risk of cold-starting (starting without preserving jobs).

The contents of the file are case insensitive except for the names of nodes and partitions. Any text following a "#" in the configuration file is treated as a comment through the end of that line. The size of each line in the file is limited to 1024 characters. Changes to the configuration file take effect upon restart of SLURM daemons, daemon receipt of the SIGHUP signal, or execution of the command "scontrol reconfigure" unless otherwise noted.

If a line begins with the word "Include" followed by whitespace and then a file name, that file will be included inline with the current configuration file.

The overall configuration parameters available include:

AccountingStorageEnforce
    If set to a non-zero value and the user, partition, account association is not defined for a job in the accounting database then prevent the job from being executed. The default value is zero.

AccountingStorageHost
    Define the name of the host where the database is running we are going to store the accounting data. Only used for database type storage plugins, ignored otherwise. Also see DefaultStorageHost.

AccountingStorageLoc
    Specifies the location of the file or database where accounting records are written. Also see DefaultStorageLoc.

AccountingStoragePass
    Define the password used to gain access to the database to store the accounting data. Only used for database type storage plugins, ignored otherwise. In the case of Slurm DBD (Data Base Daemon) with Munge authentication this can be configured to use a Munge daemon specifically configured to provide authentication between clusters while the default Munge daemon provides authentication within a cluster. In that case, AccountingStoragePass should specify the named port to be used for communications with the alternate Munge daemon (e.g. "/var/run/munge/global.socket.2"). The default value is NULL. Also see DefaultStoragePass.

AccountingStoragePort
    Define the port the database server is listening on where we are going to store the accounting data. Only used for database type storage plugins, ignored otherwise. Also see DefaultStoragePort.

AccountingStorageType
    Define the accounting storage mechanism type. Acceptable values at present include "accounting_storage/filetxt", "accounting_storage/gold", "accounting_storage/mysql", "accounting_storage/none", "accounting_storage/pgsql", and "accounting_storage/slurmdbd". The value "accounting_storage/filetxt" indicates that accounting records will be written to a the file specified by the AccountingStorageLoc parameter. The value "accounting_storage/gold" indicates that account records will be written to Gold (http://www.clusterresources.com/pages/products/gold-allocation-manager.php), which maintains its own database. The value "accounting_storage/mysql" indicates that accounting records should be written to a MySQL database specified by the AccountingStorageLoc parameter. The default value is "accounting_storage/none", which means that account records are not maintained. The value "accounting_storage/pgsql" indicates that accounting records should be written to a PostgreSQL database specified by the AccountingStorageLoc parameter. The value "accounting_storage/slurmdbd" indicates that accounting records will be written to SlurmDDB, which manages an underlying MySQL or PostgreSQL database. See "man slurmdbd" for more information. Also see DefaultStorageType.

AccountingStorageUser
    Define the name of the user we are going to connect to the database with to store the accounting data. Only used for database type storage plugins, ignored otherwise. Also see DefaultStorageUser.

AuthType
    Define the authentication method for communications between SLURM components. Acceptable values at present include "auth/none", "auth/authd", and "auth/munge". The default value is "auth/none", which means the UID included in communication messages is not verified. This may be fine for testing purposes, but do not use "auth/none" if you desire any security. "auth/authd" indicates that Brett Chun's authd is to be used (see "http://www.theether.org/authd/" for more information, Note that authd is no longer actively supported). "auth/munge" indicates that LLNL's MUNGE is to be used (this is the best supported authentication mechanism for SLURM, see "http://home.gna.org/munge/" for more information). All SLURM daemons and commands must be terminated prior to changing the value of AuthType and later restarted (SLURM jobs can be preserved).

BackupAddr
    Name that BackupController should be referred to in establishing a communications path. This name will be used as an argument to the gethostbyname() function for identification. For example, "elx0000" might be used to designate the ethernet address for node "lx0000". By default the BackupAddr will be identical in value to BackupController.

BackupController
    The name of the machine where SLURM control functions are to be executed in the event that ControlMachine fails. This node may also be used as a compute server if so desired. It will come into service as a controller only upon the failure of ControlMachine and will revert to a "standby" mode when the ControlMachine becomes available once again. This should be a node name without the full domain name (e.g. "lx0002"). While not essential, it is recommended that you specify a backup controller. See the RELOCATING CONTROLLERS section if you change this.

CacheGroups
    If set to 1, the slurmd daemon will cache /etc/groups entries. This can improve performance for highly parallel jobs if NIS servers are used and unable to respond very quickly. The default value is 0 to disable caching group data.

CheckpointType
    Define the system-initiated checkpoint method to be used for user jobs. The slurmctld daemon must be restarted for a change in CheckpointType to take effect. Acceptable values at present include "checkpoint/aix" (only on AIX systems), "checkpoint/ompi" (requires OpenMPI version 1.3 or higher), "checkpoint/xlch" (for XLCH, requires that SlurmUser be root), and "checkpoint/none". The default value is "checkpoint/none".

ClusterName
    The name by which this SLURM managed cluster is known for accounting purposes. This is needed distinguish between accounting data from multiple clusters being recorded in a single database.

ControlAddr
    Name that ControlMachine should be referred to in establishing a communications path. This name will be used as an argument to the gethostbyname() function for identification. For example, "elx0000" might be used to designate the ethernet address for node "lx0000". By default the ControlAddr will be identical in value to ControlMachine.

ControlMachine
    The name of the machine where SLURM control functions are executed. This should be a node name without the full domain name (e.g. "lx0001"). This value must be specified. See the RELOCATING CONTROLLERS section if you change this.

CryptoType
    Define the cryptographic signature tool to be used in the creation of job step credentials. The slurmctld daemon must be restarted for a change in CryptoType to take effect. Acceptable values at present include "crypto/munge" and "crypto/openssl". OpenSSL offers the best performance and is available with an Apache style open source license. Munge is a little slower, but is available under the Gnu General Public License (GPL). The default value is "crypto/openssl".

DefMemPerTask
    Default real memory size available per task in MegaBytes. Used to avoid over-subscribing memory and causing paging. Also see MaxMemPerTask. The default value is 0 (unlimited).

DefaultStorageHost
    Define the name of the host where the database is running and used to to store the accounting and job completion data. Only used for database type storage plugins, ignored otherwise. Also see AccountingStorageHost and JobCompHost.

DefaultStorageLoc
    Specifies the location of the file or database where accounting and job completion records are written. Also see AccountingStorageLoc and JobCompLoc.

DefaultStoragePass
    Define the password used to gain access to the database to store the accounting and job completion data. Only used for database type storage plugins, ignored otherwise. Also see AccountingStoragePass and JobCompPass.

DefaultStoragePort
    Define the port the database server is listening on where we are going to store the accounting and job completion data. Only used for database type storage plugins, ignored otherwise. Also see AccountingStoragePort and JobCompPort.

DefaultStorageType
    Define the accounting and job completion storage mechanism type. Acceptable values at present include "filetxt", "gold", "mysql", "none", "pgsql", and "slurmdbd". The value "filetxt" indicates that records will be written to a the file. The value "gold" indicates that records will be written to Gold (http://www.clusterresources.com/pages/products/gold-allocation-manager.php), which maintains its own database. The value "mysql" indicates that accounting records will be written to a mysql database. The default value is "none", which means that records are not maintained. The value "pgsql" indicates that records will be written to a postresql database. The value "slurmdbd" indicates that records will be written to SlurmDbd, which maintains its own database. See "man slurmdbd for more information". Also see AccountingStorageType and JobCompType.

DefaultStorageUser
    Define the name of the user we are going to connect to the database with to store the accounting and job completion data. Only used for database type storage plugins, ignored otherwise. Also see AccountingStorageUser and JobCompUser.

Epilog
    Fully qualified pathname of a script to execute as user root on every node when a user's job completes (e.g. "/usr/local/slurm/epilog"). This may be used to purge files, disable user login, etc. By default there is no epilog.

EpilogMsgTime
    The number of microseconds the the slurmctld daemon requires to process an epilog completion message from the slurmd dameons. This parameter can be used to prevent a burst of epilog completion messages from being sent at the same time which should help prevent lost messages and improve throughput for large jobs. The default value is 2000 microseconds. For a 1000 node job, this spreads the epilog completion messages out over two seconds.

FastSchedule
    Controls how a nodes configuration specifications in slurm.conf are used. If the number of node configuration entries in the configuration file is significantly lower than the number of nodes, setting FastSchedule to 1 will permit much faster scheduling decisions to be made. (The scheduler can just check the values in a few configuration records instead of possibly thousands of node records. If a job can't be initiated immediately, the scheduler may execute these tests repeatedly.) Note that on systems with hyper-threading, the processor count reported by the node will be twice the actually processor count. Consider which value you want to be used for scheduling purposes.

    1 (default)
        Consider the configuration of each node to be that specified in the configuration file and any node with less than the configured resources will be set DOWN.

    0   Base scheduling decisions upon the actual configuration of each individual node.

    2   Consider the configuration of each node to be that specified in the slurm.conf configuration file and any node with less resources than configured will not be set DOWN. This can be useful for testing purposes.

FirstJobId
    The job id to be used for the first submitted to SLURM without a specific requested value. Job id values generated will incremented by 1 for each subsequent job. This may be used to provide a meta-scheduler with a job id space which is disjoint from the interactive jobs. The default value is 1.

GetEnvTimeout
    Used for Moab scheduled jobs only. Controls how long job should wait in seconds for loading the user's environment before attempting to load it from a cache file. Applies when the srun or sbatch --get-user-env option is used. Default value is 2 seconds.

HealthCheckInterval
    The interval in seconds between executions of HealthCheckProgram. The default value is zero, which disables execution.

HealthCheckProgram
    Fully qualified pathname of a script to execute as user root periodically on all compute nodes that are not in the DOWN state. This may be used to verify the node is fully operational and DRAIN the it otherwise. The interval is controlled using the HealthCheckInterval parameter. Note that the HealthCheckProgram will be executed at the same time on all nodes to minimize its impact upon parallel programs. This program is will be killed if it does not terminate normally within 60 seconds. By default, no program will be executed.

InactiveLimit
    The interval, in seconds, a job or job step is permitted to be inactive before it is terminated. A job or job step is considered inactive if the associated srun command is not responding to slurm daemons. This could be due to the termination of the srun command or the program being is a stopped state. A batch job is considered inactive if it has no active job steps (e.g. periods of pre- and post-processing). This limit permits defunct jobs to be purged in a timely fashion without waiting for their time limit to be reached. This value should reflect the possibility that the srun command may stopped by a debugger or considerable time could be required for batch job pre- and post-processing. This limit is ignored for jobs running in partitions with the RootOnly flag set (the scheduler running as root will be responsible for the job). The default value is unlimited (zero). May not exceed 65533.

JobAcctGatherType
    Define the job accounting mechanism type. Acceptable values at present include "jobacct_gather/aix" (for AIX operating system), "jobacct_gather/linux" (for Linux operating system) and "jobacct_gather/none" (no accounting data collected). The default value is "jobacct_gather/none". In order to use the sacct tool, "jobacct_gather/aix" or "jobacct_gather/linux" must be configured.

JobAcctGatherFrequency
    Define the job accounting sampling interval. For jobacct_gather/none this parameter is ignored. For jobacct_gather/aix and jobacct_gather/linux the parameter is a number is seconds between sampling job state. The default value is 30 seconds. A value of zero disables real the periodic job sampling and provides accounting information only on job termination (reducing SLURM interference with the job).

JobCompHost
    Define the name of the host where the database is running and used to store the job completion data. Only used for database type storage plugins, ignored otherwise. Also see DefaultStorageHost.

JobCompLoc
    The interpretation of this value depends upon the logging mechanism specified by the JobCompType parameter either a filename or a database name. Also see DefaultStorageLoc.

JobCompPass
    Define the password used to gain access to the database to store the job completion data. Only used for database type storage plugins, ignored otherwise. Also see DefaultStoragePass.

JobCompPort
    Define the port the database server is listening on where we are going to store the job completion data. Only used for database type storage plugins, ignored otherwise. Also see DefaultStoragePort.

JobCompType
    Define the job completion logging mechanism type. Acceptable values at present include "jobcomp/none", "jobcomp/filetxt", "jobcomp/mysql", "jobcomp/pgsql", "jobcomp/script"and "jobcomp/slurmdbd". The default value is "jobcomp/none", which means that upon job completion the record of the job is purged from the system. The value "jobcomp/filetxt" indicates that a record of the job should be written to a text file specified by the JobCompLoc parameter. The value "jobcomp/mysql" indicates that a record of the job should be written to a mysql database specified by the JobCompLoc parameter. The value "jobcomp/pgsql" indicates that a record of the job should be written to a postgresql database specified by the JobCompLoc parameter. The value "jobcomp/script" indicates that a script specified by the JobCompLoc parameter is to be executed with environment variables indicating the job information. The value "jobcomp/slurmdbd" indicates that job completion records will be written to SlurmDbd, which maintains its own database. See "man slurmdbd" for more information. Also see DefaultStorageType.

JobCompUser
    Define the name of the user we are going to connect to the database with to store the job completion data. Only used for database type storage plugins, ignored otherwise. Also see DefaultStorageUser.

JobCredentialPrivateKey
    Fully qualified pathname of a file containing a private key used for authentication by Slurm daemons. This parameter is ignored if CryptType=munge.

JobCredentialPublicCertificate
    Fully qualified pathname of a file containing a public key used for authentication by Slurm daemons. This parameter is ignored if CryptType=munge.

JobFileAppend
    This option controls what to do if a job's output or error file exist when the job is started. If JobFileAppend is set to a value of 1, then append to the existing file. By default, any existing file is truncated.

JobRequeue
    This option controls what to do by default after a node failure. If JobRequeue is set to a value of 1, then any job running on the failed node will be requeued for execution on different nodes. If JobRequeue is set to a value of 0, then any job running on the failed node will be terminated. Use the sbatch --no-requeue or --requeue option to change the default behavior for individual jobs. The default value is 1.

KillWait
    The interval, in seconds, given to a job's processes between the SIGTERM and SIGKILL signals upon reaching its time limit. If the job fails to terminate gracefully in the interval specified, it will be forcibly terminated. The default value is 30 seconds. May not exceed 65533.

Licenses
    Specification of licenses (or other resources available on all nodes of the cluster) which can be allocated to jobs. License names can optionally be followed by an asterisk and count with a default count of one. Multiple license names should be comma separated (e.g. "Licenses=foo*4,bar"). Note that SLURM prevents jobs from being scheduled if their required license specification is not available. SLURM does not prevent jobs from using licenses that are not explicitly listed in the job submission specification.

MailProg
    Fully qualified pathname to the program used to send email per user request. The default value is "/bin/mail".

MaxJobCount
    The maximum number of jobs SLURM can have in its active database at one time. Set the values of MaxJobCount and MinJobAge to insure the slurmctld daemon does not exhaust its memory or other resources. Once this limit is reached, requests to submit additional jobs will fail. The default value is 5000 jobs. This value may not be reset via "scontrol reconfig". It only takes effect upon restart of the slurmctld daemon. May not exceed 65533.

MaxMemPerTask
    Maximum real memory size available per task in MegaBytes. Used to avoid over-subscribing memory and causing paging. Also see DefMemPerTask. The default value is 0 (unlimited).

MessageTimeout
    Time permitted for a round-trip communication to complete in seconds. Default value is 10 seconds. For systems with shared nodes, the slurmd daemon could be paged out and necessitate higher values.

MinJobAge
    The minimum age of a completed job before its record is purged from SLURM's active database. Set the values of MaxJobCount and MinJobAge to insure the slurmctld daemon does not exhaust its memory or other resources. The default value is 300 seconds. A value of zero prevents any job record purging. May not exceed 65533.

MpiDefault
    Identifies the default type of MPI to be used. Srun may override this configuration parameter in any case. Currently supported versions include: mpichgm, mvapich, none (default, which works for many other versions of MPI including LAM MPI and Open MPI).

PluginDir
    Identifies the places in which to look for SLURM plugins. This is a colon-separated list of directories, like the PATH environment variable. The default value is "/usr/local/lib/slurm".

PlugStackConfig
    Location of the config file for SLURM stackable plugins that use the Stackable Plugin Architecture for Node job (K)control (SPANK). This provides support for a highly configurable set of plugins to be called before and/or after execution of each task spawned as part of a user's job step. Default location is "plugstack.conf" in the same directory as the system slurm.conf. For more information on SPANK plugins, see the spank(8) manual.

PrivateData
    If non-zero then users are unable to view jobs or job steps belonging to other users (except for SlurmUser or root, who can view all jobs). The default value is "0", permitting any user to view any jobs or job steps.

ProctrackType
    Identifies the plugin to be used for process tracking. The slurmd daemon uses this mechanism to identify all processes which are children of processes it spawns for a user job. The slurmd daemon must be restarted for a change in ProctrackType to take effect. NOTE: "proctrack/linuxproc" and "proctrack/pgid" can fail to identify all processes associated with a job since processes can become a child of the init process (when the parent process terminates) or change their process group. To reliably track all processes, one of the other mechanisms utilizing kernel modifications is preferable. NOTE: "proctrack/linuxproc" is not compatible with "switch/elan." Acceptable values at present include:

    proctrack/aix which uses an AIX kernel extension and is
        the default for AIX systems

    proctrack/linuxproc which uses linux process tree using
        parent process IDs

    proctrack/rms which uses Quadrics kernel patch and is the
        default if "SwitchType=switch/elan"

    proctrack/sgi_job which uses SGI's Process Aggregates (PAGG)
        kernel module, see http://oss.sgi.com/projects/pagg/ for more information

    proctrack/pgid which uses process group IDs and is the
        default for all other systems

Prolog
    Fully qualified pathname of a script for the slurmd to execute whenever it is asked to run a job step from a new job allocation. (e.g. "/usr/local/slurm/prolog"). The slurmd executes the script before starting the job step. This may be used to purge files, enable user login, etc. By default there is no prolog. Any configured script is expected to complete execution quickly (in less time than MessageTimeout). NOTE: The Prolog script is ONLY run on any individual node when it first sees a job step from a new allocation; it does not run the Prolog immediately when an allocation is granted. If no job steps from an allocation are run on a node, it will never run the Prolog for that allocation. The Epilog, on the other hand, always runs on every node of an allocation when the allocation is released.

PropagatePrioProcess
    Setting PropagatePrioProcess to "1", will cause a users job to run with the same priority (aka nice value) as the users process which launched the job on the submit node. If set to "0", or left unset, the users job will inherit the scheduling priority from the slurm daemon.

PropagateResourceLimits
    A list of comma separated resource limit names. The slurmd daemon uses these names to obtain the associated (soft) limit values from the users process environment on the submit node. These limits are then propagated and applied to the jobs that will run on the compute nodes. This parameter can be useful when system limits vary among nodes. Any resource limits that do not appear in the list are not propagated. However, the user can override this by specifying which resource limits to propagate with the srun commands "--propagate" option. If neither of the 'propagate resource limit' parameters are specified, then the default action is to propagate all limits. Only one of the parameters, either PropagateResourceLimits or PropagateResourceLimitsExcept, may be specified. The following limit names are supported by Slurm (although some options may not be supported on some systems):

    ALL All limits listed below

    AS  The maximum address space for a processes

    CORE
        The maximum size of core file

    CPU The maximum amount of CPU time

    DATA
        The maximum size of a process's data segment

    FSIZE
        The maximum size of files created

    MEMLOCK
        The maximum size that may be locked into memory

    NOFILE
        The maximum number of open files

    NPROC
        The maximum number of processes available

    RSS The maximum resident set size

    STACK
        The maximum stack size

PropagateResourceLimitsExcept
    A list of comma separated resource limit names. By default, all resource limits will be propagated, (as described by the PropagateResourceLimits parameter), except for the limits appearing in this list. The user can override this by specifying which resource limits to propagate with the srun commands "--propagate" option. See PropagateResourceLimits above for a list of valid limit names.

ResumeProgram
    SLURM supports a mechanism to reduce power consumption on nodes that remain idle for an extended period of time. This is typically accomplished by reducing voltage and frequency. ResumeProgram is the program that will be executed when a node in power save mode is assigned work to perform. The program executes as SlurmUser. The argument to the program will be the names of nodes to be removed from power savings mode (using SLURM's hostlist expression format). By default no program is run. Related configuration options include ResumeRate, SuspendRate, SuspendTime, SuspendProgram, SuspendExcNodes, and SuspendExcParts. More information is available at the SLURM web site (https://computing.llnl.gov/linux/slurm/power_save.html).

ResumeRate
    The rate at which nodes in power save mode are returned to normal operation by ResumeProgram. The value is number of nodes per minute and it can be used to prevent power surges if a large number of nodes in power save mode are assigned work at the same time (e.g. a large job starts). A value of zero results in no limits being imposed. The default value is 60 nodes per minute. Related configuration options include ResumeProgram, SuspendRate, SuspendTime, SuspendProgram, SuspendExcNodes, and SuspendExcParts.

ReturnToService
    If set to 1, then a non-responding (DOWN) node will become available for use upon registration. Note that DOWN node's state will be changed only if it was set DOWN due to being non-responsive. If the node was set DOWN for any other reason (low memory, prolog failure, epilog failure, etc.), its state will not automatically be changed. The default value is 0, which means that a node will remain in the DOWN state until a system administrator explicitly changes its state (even if the slurmd daemon registers and resumes communications).

SchedulerPort
    The port number on which slurmctld should listen for connection requests. This value is only used by the Maui Scheduler (see SchedulerType). The default value is 7321.

SchedulerRootFilter
    Identifies whether or not RootOnly partitions should be filtered from any external scheduling activities. If set to 0, then RootOnly partitions are treated like any other partition. If set to 1, then RootOnly partitions are exempt from any external scheduling activities. The default value is 1. Currently only used by the built-in backfill scheduling module "sched/backfill" (see SchedulerType).

SchedulerTimeSlice
    Number of seconds in each time slice when SchedulerType=sched/gang. The default value is 30.

SchedulerType
    Identifies the type of scheduler to be used. Acceptable values include "sched/builtin" for the built-in FIFO scheduler, "sched/backfill" for a backfill scheduling module to augment the default FIFO scheduling, "sched/gang" for gang scheduler (time-slicing of parallel jobs), "sched/hold" to hold all newly arriving jobs if a file "/etc/slurm.hold" exists otherwise use the built-in FIFO scheduler, and "sched/wiki" for the Wiki interface to the Maui Scheduler. The default value is "sched/builtin". Backfill scheduling will initiate lower-priority jobs if doing so does not delay the expected initiation time of any higher priority job. Note that this backfill scheduler implementation is relatively simple. It does not support partitions configured to to share resources (run multiple jobs on the same nodes) or support jobs requesting specific nodes. When initially setting the value to "sched/wiki", any pending jobs must have their priority set to zero (held). When changing the value from "sched/wiki", all pending jobs should have their priority change from zero to some large number. The scontrol command can be used to change job priorities. The slurmctld daemon must be restarted for a change in scheduler type to become effective.

SelectType
    Identifies the type of resource selection algorithm to be used. Acceptable values include

    select/linear
        for allocation of entire nodes assuming a one-dimensional array of nodes in which sequentially ordered nodes are preferable. This is the default value for non-BlueGene systems.

    select/cons_res
        The resources within a node are individually allocated as consumable resources. Note that whole nodes can be allocated to jobs for selected partitions by using the Shared=Exclusive option. See the partition Shared parameter for more information.

    select/bluegene
        for a three-dimensional BlueGene system. The default value is "select/bluegene" for BlueGene systems.

SelectTypeParameters
    The permitted values of SelectTypeParameters depend upon the configured value of SelectType. SelectType=select/bluegene supports no SelectTypeParameters. The only supported option for SelectType=select/linear is CR_Memory, which treats memory as a consumable resource and prevents memory over subscription with job preemption or gang scheduling. The following values are supported for SelectType=select/cons_res:

    CR_CPU
        CPUs are consumable resources. There is no notion of sockets, cores or threads. On a multi-core system, each core will be considered a CPU. On a multi-core and hyperthreaded system, each thread will be considered a CPU. On single-core systems, each CPUs will be considered a CPU.

    CR_CPU_Memory
        CPUs and memory are consumable resources.

    CR_Core
        Cores are consumable resources.

    CR_Core_Memory
        Cores and memory are consumable resources.

    CR_Socket
        Sockets are consumable resources.

    CR_Socket_Memory
        Memory and CPUs are consumable resources.

    CR_Memory
        Memory is a consumable resource. NOTE: This implies Shared=YES or Shared=FORCE for all partitions.

SlurmUser
    The name of the user that the slurmctld daemon executes as. For security purposes, a user other than "root" is recommended. The default value is "root".

SlurmctldDebug
    The level of detail to provide slurmctld daemon's logs. Values from 0 to 7 are legal, with `0' being "quiet" operation and `7' being insanely verbose. The default value is 3.

SlurmctldLogFile
    Fully qualified pathname of a file into which the slurmctld daemon's logs are written. The default value is none (performs logging via syslog).

SlurmctldPidFile
    Fully qualified pathname of a file into which the slurmctld daemon may write its process id. This may be used for automated signal processing. The default value is "/var/run/slurmctld.pid".

SlurmctldPort
    The port number that the SLURM controller, slurmctld, listens to for work. The default value is SLURMCTLD_PORT as established at system build time. If none is explicitly specified, it will be set to 6817. NOTE: Either slurmctld and slurmd daemons must not execute on the same nodes or the values of SlurmctldPort and SlurmdPort must be different.

SlurmctldTimeout
    The interval, in seconds, that the backup controller waits for the primary controller to respond before assuming control. The default value is 120 seconds. May not exceed 65533.

SlurmdDebug
    The level of detail to provide slurmd daemon's logs. Values from 0 to 7 are legal, with `0' being "quiet" operation and `7' being insanely verbose. The default value is 3.

SlurmdLogFile
    Fully qualified pathname of a file into which the slurmd daemon's logs are written. The default value is none (performs logging via syslog). Any "%h" within the name is replaced with the hostname on which the slurmd is running.

SlurmdPidFile
    Fully qualified pathname of a file into which the slurmd daemon may write its process id. This may be used for automated signal processing. The default value is "/var/run/slurmd.pid".

SlurmdPort
    The port number that the SLURM compute node daemon, slurmd, listens to for work. The default value is SLURMD_PORT as established at system build time. If none is explicitly specified, its value will be 6818. NOTE: Either slurmctld and slurmd daemons must not execute on the same nodes or the values of SlurmctldPort and SlurmdPort must be different.

SlurmdSpoolDir
    Fully qualified pathname of a directory into which the slurmd daemon's state information and batch job script information are written. This must be a common pathname for all nodes, but should represent a directory which is local to each node (reference a local file system). The default value is "/var/spool/slurmd." NOTE: This directory is also used to store slurmd's shared memory lockfile, and should not be changed unless the system is being cleanly restarted. If the location of SlurmdSpoolDir is changed and slurmd is restarted, the new daemon will attach to a different shared memory region and lose track of any running jobs.

SlurmdTimeout
    The interval, in seconds, that the SLURM controller waits for slurmd to respond before configuring that node's state to DOWN. The default value is 300 seconds. A value of zero indicates the node will not be tested by slurmctld to confirm the state of slurmd, the node will not be automatically set to a DOWN state indicating a non-responsive slurmd, and some other tool will take responsibility for monitoring the state of each compute node and its slurmd daemon. The value may not exceed 65533.

SrunEpilog
    Fully qualified pathname of an executable to be run by srun following the completion of a job step. The command line arguments for the executable will be the command and arguments of the job step. This configuration parameter may be overridden by srun's --epilog parameter.

SrunProlog
    Fully qualified pathname of an executable to be run by srun prior to the launch of a job step. The command line arguments for the executable will be the command and arguments of the job step. This configuration parameter may be overridden by srun's --prolog parameter.

StateSaveLocation
    Fully qualified pathname of a directory into which the SLURM controller, slurmctld, saves its state (e.g. "/usr/local/slurm/checkpoint"). SLURM state will saved here to recover from system failures. SlurmUser must be able to create files in this directory. If you have a BackupController configured, this location should be readable and writable by both systems. Since all running and pending job information is stored here, the use of a reliable file system (e.g. RAID) is recommended. The default value is "/tmp". If any slurm daemons terminate abnormally, their core files will also be written into this directory.

SuspendExcNodes
    Specifies the nodes which are to not be placed in power save mode, even if the node remains idle for an extended period of time. Use SLURM's hostlist expression to identify nodes. By default no nodes are excluded. Related configuration options include ResumeProgram, ResumeRate, SuspendProgram, SuspendRate, SuspendTime and SuspendExcParts.

SuspendExcParts
    Specifies the partitions whose nodes are to not be placed in power save mode, even if the node remains idle for an extended period of time. Multiple partitions can be identified and separated by commas. By default no nodes are excluded. Related configuration options include ResumeProgram, ResumeRate, SuspendProgram, SuspendRate, SuspendTime and SuspendExcNodes.

SuspendProgram
    SuspendProgram is the program that will be executed when a node remains idle for an extended period of time. This program is expected to place the node into some power save mode. The program executes as SlurmUser. The argument to the program will be the names of nodes to be placed into power savings mode (using SLURM's hostlist expression format). By default no program is run. Related configuration options include ResumeProgram, ResumeRate, SuspendRate, SuspendTime, SuspendExcNodes, and SuspendExcParts.

SuspendRate
    The rate at which nodes are place into power save mode by SuspendProgram. The value is number of nodes per minute and it can be used to prevent a large drop in power power consumption (e.g. after a large job completes). A value of zero results in no limits being imposed. The default value is 60 nodes per minute. Related configuration options include ResumeProgram, ResumeRate, SuspendProgram, SuspendTime, SuspendExcNodes, and SuspendExcParts.

SuspendTime
    Nodes which remain idle for this number of seconds will be placed into power save mode by SuspendProgram, A value of -1 disables power save mode and is the default. Related configuration options include ResumeProgram, ResumeRate, SuspendProgram, SuspendRate, SuspendExcNodes, and SuspendExcParts.

SwitchType
    Identifies the type of switch or interconnect used for application communications. Acceptable values include "switch/none" for switches not requiring special processing for job launch or termination (Myrinet, Ethernet, and InfiniBand), "switch/elan" for Quadrics Elan 3 or Elan 4 interconnect. The default value is "switch/none". All SLURM daemons, commands and running jobs must be restarted for a change in SwitchType to take effect. If running jobs exist at the time slurmctld is restarted with a new value of SwitchType, records of all jobs in any state may be lost.

TaskEpilog
    Fully qualified pathname of a program to be execute as the slurm job's owner after termination of each task. See TaskPlugin for execution order details.

TaskPlugin
    Identifies the type of task launch plugin, typically used to provide resource management within a node (e.g. pinning tasks to specific processors). Acceptable values include "task/none" for systems requiring no special handling and "task/affinity" to enable the --cpu_bind and/or --mem_bind srun options. The default value is "task/none". If you "task/affinity" and encounter problems, it may be due to the variety of system calls used to implement task affinity on different operating systems. If that is the case, you may want to use Portable Linux Process Affinity (PLPA, see http://www.open-mpi.org/software/plpa), which is supported by SLURM. The order of task prolog/epilog execution is as follows:

    1. pre_launch(): function in TaskPlugin

    2. TaskProlog: system-wide per task program defined in slurm.conf

    3. user prolog: job step specific task program defined using
        srun's --task-prolog option or SLURM_TASK_PROLOG environment variable

    4. Execute the job step's task

    5. user epilog: job step specific task program defined using
        srun's --task-epilog option or SLURM_TASK_EPILOG environment variable

    6. TaskEpilog: system-wide per task program defined in slurm.conf

    7. post_term(): function in TaskPlugin

TaskPluginParam
    Optional parameters for the task plugin.

    Cpusets
        Use cpusets to perform task affinity functions

    Sched
        Use sched_setaffinity or plpa_sched_setaffinity (if available) to bind tasks to processors. This is the default mode of operation is no parameters are specified.

TaskProlog
    Fully qualified pathname of a program to be execute as the slurm job's owner prior to initiation of each task. Besides the normal environment variables, this has SLURM_TASK_PID available to identify the process ID of the task being started. Standard output from this program of the form "export NAME=value" will be used to set environment variables for the task being spawned. See TaskPlugin for execution order details.

TmpFS
    Fully qualified pathname of the file system available to user jobs for temporary storage. This parameter is used in establishing a node's TmpDisk space. The default value is "/tmp".

TreeWidth
    Slurmd daemons use a virtual tree network for communications. TreeWidth specifies the width of the tree (i.e. the fanout). The default value is 50, meaning each slurmd daemon can communicate with up to 50 other slurmd daemons and over 2500 nodes can be contacted with two message hops. The default value will work well for most clusters. Optimal system performance can typically be achieved if TreeWidth is set to the square root of the number of nodes in the cluster for systems having no more than 2500 nodes or the cube root for larger systems.

UnkillableStepProgram
    If the processes in a job step are determined to be unkillable for a period of time specified by the UnkillableStepTimeout variable, the program specified by the UnkillableStepProgram string will be executed. This program can be used to take special actions to clean up the unkillable processes. The program will be run as the same user as the slurmd (usually "root").

UnkillableStepTimeout
    The length of time, in seconds, that SLURM will wait before deciding that processes in a job step are unkillable (after they have been signaled with SIGKILL). The default timeout value is 60 seconds.

UsePAM
    If set to 1, PAM (Pluggable Authentication Modules for Linux) will be enabled. PAM is used to establish the upper bounds for resource limits. With PAM support enabled, local system administrators can dynamically configure system resource limits. Changing the upper bound of a resource limit will not alter the limits of running jobs, only jobs started after a change has been made will pick up the new limits. The default value is 0 (not to enable PAM support). Remember that PAM also needs to be configured to support SLURM as a service. For sites using PAM's directory based configuration option, a configuration file named slurm should be created. The module-type, control-flags, and module-path names that should be included in the file are:
    auth required pam_localuser.so
    auth required pam_shells.so
    account required pam_unix.so
    account required pam_access.so
    session required pam_unix.so
    For sites configuring PAM with a general configuration file, the appropriate lines (see above), where slurm is the service-name, should be added.

WaitTime
    Specifies how many seconds the srun command should by default wait after the first task terminates before terminating all remaining tasks. The "--wait" option on the srun command line overrides this value. If set to 0, this feature is disabled. May not exceed 65533.

The configuration of nodes (or machines) to be managed by Slurm is also specified in /etc/slurm.conf. Only the NodeName must be supplied in the configuration file. All other node configuration information is optional. It is advisable to establish baseline node configurations, especially if the cluster is heterogeneous. Nodes which register to the system with less than the configured resources (e.g. too little memory), will be placed in the "DOWN" state to avoid scheduling jobs on them. Establishing baseline configurations will also speed SLURM's scheduling process by permitting it to compare job requirements against these (relatively few) configuration parameters and possibly avoid having to check job requirements against every individual node's configuration. The resources checked at node registration time are: Procs, RealMemory and TmpDisk. While baseline values for each of these can be established in the configuration file, the actual values upon node registration are recorded and these actual values may be used for scheduling purposes (depending upon the value of FastSchedule in the configuration file.

Default values can be specified with a record in which "NodeName" is "DEFAULT". The default entry values will apply only to lines following it in the configuration file and the default values can be reset multiple times in the configuration file with multiple entries where "NodeName=DEFAULT". The "NodeName=" specification must be placed on every line describing the configuration of nodes. In fact, it is generally possible and desirable to define the configurations of all nodes in only a few lines. This convention permits significant optimization in the scheduling of larger clusters. In order to support the concept of jobs requiring consecutive nodes on some architectures, node specifications should be place in this file in consecutive order. No single node name may be listed more than once in the configuration file. Use "DownNodes=" to record the state of nodes which are temporarily in a DOWN, DRAIN or FAILING state without altering permanent configuration information. A job step's tasks are allocated to nodes in order the nodes appear in the configuration file. There is presently no capability within SLURM to arbitrarily order a job step's tasks.

Multiple node names may be comma separated (e.g. "alpha,beta,gamma") and/or a simple node range expression may optionally be used to specify numeric ranges of nodes to avoid building a configuration file with large numbers of entries. The node range expression can contain one pair of square brackets with a sequence of comma separated numbers and/or ranges of numbers separated by a "-" (e.g. "linux[0-64,128]", or "lx[15,18,32-33]"). Note that the numeric ranges can include one or more leading zeros to indicate the numeric portion has a fixed number of digits (e.g. "linux[0000-1023]").

On BlueGene systems only, the square brackets should contain pairs of three digit numbers separated by a "x". These numbers indicate the boundaries of a rectangular prism (e.g. "bgl[000x144,400x544]"). See BlueGene documentation for more details. Presently the numeric range must be the last characters in the node name (e.g. "unit[0-31]rack1" is invalid). The node configuration specified the following information:

NodeName
    Name that SLURM uses to refer to a node (or base partition for BlueGene systems). Typically this would be the string that "/bin/hostname -s" returns, however it may be an arbitrary string if NodeHostname is specified. If the NodeName is "DEFAULT", the values specified with that record will apply to subsequent node specifications unless explicitly set to other values in that node record or replaced with a different set of default values. For architectures in which the node order is significant, nodes will be considered consecutive in the order defined. For example, if the configuration for "NodeName=charlie" immediately follows the configuration for "NodeName=baker" they will be considered adjacent in the computer.

NodeHostname
    The string that "/bin/hostname -s" returns. A node range expression can be used to specify a set of nodes. If an expression is used, the number of nodes identified by NodeHostname on a line in the configuration file must be identical to the number of nodes identified by NodeName. By default, the NodeHostname will be identical in value to NodeName.

NodeAddr
    Name that a node should be referred to in establishing a communications path. This name will be used as an argument to the gethostbyname() function for identification. If a node range expression is used to designate multiple nodes, they must exactly match the entries in the NodeName (e.g. "NodeName=lx[0-7] NodeAddr="elx[0-7]"). NodeAddr may also contain IP addresses. By default, the NodeAddr will be identical in value to NodeName.

CoresPerSocket
    Number of cores in a single physical processor socket (e.g. "2"). The CoresPerSocket value describes physical cores, not the logical number of processors per socket. NOTE: If you have multi-core processors, you will likely need to specify this parameter in order to optimize scheduling. The default value is 1.

Feature
    A comma delimited list of arbitrary strings indicative of some characteristic associated with the node. There is no value associated with a feature at this time, a node either has a feature or it does not. If desired a feature may contain a numeric component indicating, for example, processor speed. By default a node has no features.

Procs
    Number of logical processors on the node (e.g. "2"). If Procs is omitted, it will be inferred from Sockets, CoresPerSocket, and ThreadsPerCore. The default value is 1.

RealMemory
    Size of real memory on the node in MegaBytes (e.g. "2048"). The default value is 1.

Reason
    Identifies the reason for a node being in state "DOWN", "DRAINED" "DRAINING", "FAIL" or "FAILING". Use quotes to enclose a reason having more than one word.

Sockets
    Number of physical processor sockets/chips on the node (e.g. "2"). If Sockets is omitted, it will be inferred from Procs, CoresPerSocket, and ThreadsPerCore. NOTE: If you have multi-core processors, you will likely need to specify these parameters. The default value is 1.

State
    State of the node with respect to the initiation of user jobs. Acceptable values are "DOWN", "DRAIN", "FAIL", "FAILING" and "UNKNOWN". "DOWN" indicates the node failed and is unavailable to be allocated work. "DRAIN" indicates the node is unavailable to be allocated work. "FAIL" indicates the node is expected to fail soon, has no jobs allocated to it, and will not be allocated to any new jobs. "FAILING" indicates the node is expected to fail soon, has one or more jobs allocated to it, but will not be allocated to any new jobs. "UNKNOWN" indicates the node's state is undefined (BUSY or IDLE), but will be established when the slurmd daemon on that node registers. The default value is "UNKNOWN". Also see the DownNodes parameter below.

ThreadsPerCore
    Number of logical threads in a single physical core (e.g. "2"). The default value is 1.

TmpDisk
    Total size of temporary disk storage in TmpFS in MegaBytes (e.g. "16384"). TmpFS (for "Temporary File System") identifies the location which jobs should use for temporary storage. Note this does not indicate the amount of free space available to the user on the node, only the total file system size. The system administration should insure this file system is purged as needed so that user jobs have access to most of this space. The Prolog and/or Epilog programs (specified in the configuration file) might be used to insure the file system is kept clean. The default value is 0.

Weight
    The priority of the node for scheduling purposes. All things being equal, jobs will be allocated the nodes with the lowest weight which satisfies their requirements. For example, a heterogeneous collection of nodes might be placed into a single partition for greater system utilization, responsiveness and capability. It would be preferable to allocate smaller memory nodes rather than larger memory nodes if either will satisfy a job's requirements. The units of weight are arbitrary, but larger weights should be assigned to nodes with more processors, memory, disk space, higher processor speed, etc. Weight is an integer value with a default value of 1.

The "DownNodes=" configuration permits you to mark certain nodes as in a DOWN, DRAIN, FAIL, or FAILING state without altering the permanent configuration information listed under a "NodeName=" specification.

DownNodes
    Any node name, or list of node names, from the "NodeName=" specifications.

Reason
    Identifies the reason for a node being in state "DOWN", "DRAIN", "FAIL" or "FAILING. Use quotes to enclose a reason having more than one word.

State
    State of the node with respect to the initiation of user jobs. Acceptable values are "BUSY", "DOWN", "DRAIN", "FAIL", "FAILING, "IDLE", and "UNKNOWN". "DOWN" indicates the node failed and is unavailable to be allocated work. "DRAIN" indicates the node is unavailable to be allocated work. "FAIL" indicates the node is expected to fail soon, has no jobs allocated to it, and will not be allocated to any new jobs. "FAILING" indicates the node is expected to fail soon, has one or more jobs allocated to it, but will not be allocated to any new jobs. "UNKNOWN" indicates the node's state is undefined (BUSY or IDLE), but will be established when the slurmd daemon on that node registers. The default value is "UNKNOWN".

The partition configuration permits you to establish different job limits or access controls for various groups (or partitions) of nodes. Nodes may be in more than one partition, making partitions serve as general purpose queues. For example one may put the same set of nodes into two different partitions, each with different constraints (time limit, job sizes, groups allowed to use the partition, etc.). Jobs are allocated resources within a single partition. Default values can be specified with a record in which "PartitionName" is "DEFAULT". The default entry values will apply only to lines following it in the configuration file and the default values can be reset multiple times in the configuration file with multiple entries where "PartitionName=DEFAULT". The "PartitionName=" specification must be placed on every line describing the configuration of partitions. NOTE: Put all parameters for each partition on a single line. Each line of partition configuration information should represent a different partition. The partition configuration file contains the following information:

AllowGroups
    Comma separated list of group IDs which may execute jobs in the partition. If at least one group associated with the user attempting to execute the job is in AllowGroups, he will be permitted to use this partition. Jobs executed as user root can use any partition without regard to the value of AllowGroups. If user root attempts to execute a job as another user (e.g. using srun's --uid option), this other user must be in one of groups identified by AllowGroups for the job to successfully execute. The default value is "ALL".

Default
    If this keyword is set, jobs submitted without a partition specification will utilize this partition. Possible values are "YES" and "NO". The default value is "NO".

Hidden
    Specifies if the partition and its jobs are to be hidden by default. Hidden partitions will by default not be reported by the SLURM APIs or commands. Possible values are "YES" and "NO". The default value is "NO".

MaxNodes
    Maximum count of nodes (or base partitions for BlueGene systems) which may be allocated to any single job. The default value is "UNLIMITED", which is represented internally as -1. This limit does not apply to jobs executed by SlurmUser or user root.

MaxTime
    Maximum run time limit for jobs. Format is minutes, minutes:seconds, hours:minutes:seconds, days-hours, days-hours:minutes, days-hours:minutes:seconds or "UNLIMITED". Time resolution is one minute and second values are rounded up to the next minute. This limit does not apply to jobs executed by SlurmUser or user root.

MinNodes
    Minimum count of nodes (or base partitions for BlueGene systems) which may be allocated to any single job. The default value is 1. This limit does not apply to jobs executed by SlurmUser or user root.

Nodes
    Comma separated list of nodes (or base partitions for BlueGene systems) which are associated with this partition. Node names may be specified using the node range expression syntax described above. A blank list of nodes (i.e. "Nodes= ") can be used if one wants a partition to exist, but have no resources (possibly on a temporary basis).

PartitionName
    Name by which the partition may be referenced (e.g. "Interactive"). This name can be specified by users when submitting jobs. If the PartitionName is "DEFAULT", the values specified with that record will apply to subsequent partition specifications unless explicitly set to other values in that partition record or replaced with a different set of default values.

Priority
    Jobs submitted to a higher priority partition will be dispatched before pending jobs in lower priority partitions and if possible they will preempt running jobs from lower priority partitions. Note that a partition's priority takes precedence over a job's priority. The value may not exceed 65533.

RootOnly
    Specifies if only user ID zero (i.e. user root) may allocate resources in this partition. User root may allocate resources for any other user, but the request must be initiated by user root. This option can be useful for a partition to be managed by some external entity (e.g. a higher-level job manager) and prevents users from directly using those resources. Possible values are "YES" and "NO". The default value is "NO".

Shared
    Controls the ability of the partition to execute more than one job at a time on each node. Possible values are "EXCLUSIVE", "FORCE", "YES", and "NO". "EXCLUSIVE" allocates entire nodes to jobs even with select/cons_res configured. This can be used to allocate whole nodes in some partitions and individual processors in other partitions. "FORCE" makes all nodes in the partition available for sharing without user means of disabling it. "YES" makes nodes in the partition available for sharing if and only if the individual jobs permit sharing (see the srun "--share" option). "NO" makes nodes unavailable for sharing under all circumstances. The default value is "NO". The "FORCE" and "YES" options can be followed by a colon and a job count. For example "Shared=YES:4". If resources are to be shared, avoiding memory over-subscription is very important. With sched/gang this count is the maximum number of jobs permitted on each resource in either running or suspended state (i.e. the total number of jobs being time sliced). With other schedulers, this count is the maximum number of running jobs on each resource (node, socket or core depending upon the SelectTypeParameters). SelectTypeParameters should be configured to treat memory as a consumable resource and the --mem option should be used for job allocations.

State
    State of partition or availability for use. Possible values are "UP" or "DOWN". The default value is "UP".

RELOCATING CONTROLLERS
If the cluster's computers used for the primary or backup controller will be out of service for an extended period of time, it may be desirable to relocate them. In order to do so, follow this procedure:

1. Stop the SLURM daemons
2. Modify the slurm.conf file appropriately
3. Distribute the updated slurm.conf file to all nodes
4. Restart the SLURM daemons

There should be no loss of any running or pending jobs. Insure that any nodes added to the cluster have the current slurm.conf file installed.

CAUTION: If two nodes are simultaneously configured as the primary controller (two nodes on which ControlMachine specify the local host and the slurmctld daemon is executing on each), system behavior will be destructive. If a compute node has an incorrect ControlMachine or BackupController parameter, that node may be rendered unusable, but no other harm will result.
