NEWS

 -- Fix handling of requeued jobs with steps that are still finishing.
 -- Cleaner copy for PriorityWeightTRES, it also fixes a core dump when trying
    to free it otherwise.
 -- Add environment variables SLURM_ARRAY_TASK_MAX, SLURM_ARRAY_TASK_MIN,
    SLURM_ARRAY_TASK_STEP for job arrays.
 -- Fix srun to use the NoInAddrAny TopologyParam option.
 -- Change QOS flag name from PartitionQOS to OverPartQOS to be a better
    description.
 -- Fix rpmbuild issue on Centos7.

* Changes in Slurm 15.08.0rc1
==============================
 -- Added power_cpufreq layout.
 -- Make complete_batch_script RPC work with message aggregation.
 -- Do not count slurmctld threads waiting in a "throttle" lock against the
    daemon's thread limit as they are not contending for resources.
 -- Modify slurmctld outgoing RPC logic to support more parallel tasks (up to
    85 RPCs and 256 pthreads; the old logic supported up to 21 RPCs and 256
    threads). This change can dramatically improve performance for RPCs
    operating on small node counts.
 -- Increase total backfill scheduler run time in stats_info_response_msg data
    structure from 32 to 64 bits in order to prevent overflow.
 -- Add NoInAddrAny option to TopologyParam in the slurm.conf which allows to
    bind to the interface of return of gethostname instead of any address on
    the node which avoid RSIP issues in Cray systems.  This is most likely
    useful in other systems as well.
 -- Fix memory leak in Slurm::load_jobs perl api call.
 -- Added --noconvert option to sacct, sstat, squeue and sinfo which allows
    values to be displayed in their original unit types (e.g. 2048M won't be
    converted to 2G).
 -- Fix spelling of node_rescrs to node_resrcs in Perl API.
 -- Fix node state race condition, UNKNOWN->IDLE without configuration info.
 -- Cray: Disable LDAP references from slurmstepd on job launch due for
    improved scalability.
 -- Remove srun "read header error" due to application termination race
    condition.
 -- Optimize sacct queries with additional db indexes.
 -- Add SLURM_TOPO_LEN env variable for scontrol show topology.
 -- Add free_mem to node information.
 -- Fix abort of batch launch if prolog is running, wait for prolog instead.
 -- Fix case where job would get the wrong cpu count when using
    --ntasks-per-core and --cpus-per-task together.
 -- Add TRESBillingWeights to partitions in slurm.conf which allows taking into
    consideration any TRES Type when calculating the usage of a job.
 -- Add PriorityWeightTRES slurm.conf option to be able to configure priority
    factors for TRES types.

* Changes in Slurm 15.08.0pre6
==============================
 -- Add scontrol options to view and modify layouts tables.
 -- Add MsgAggregationParams which controls a reverse tree to the slurmctld
    which can be used to aggregate messages to the slurmctld into a single
    message to reduce communication to the slurmctld.  Currently only epilog
    complete messages and node registration messages use this logic.
 -- Add sacct and squeue options to print trackable resources.
 -- Add sacctmgr option to display trackable resources.
 -- If an salloc or srun command is executed on a "front-end" configuration,
    that job will be assigned a slurmd shepherd daemon on the same host as used
    to execute the command when possible rather than an slurmd daemon on an
    arbitrary front-end node.
 -- Add srun --accel-bind option to control how tasks are bound to GPUs and NIC
    Generic RESources (GRES).
 -- gres/nic plugin modified to set OMPI_MCA_btl_openib_if_include environment
    variable based upon allocated devices (usable with OpenMPI and Melanox).
 -- Make it so info options for srun/salloc/sbatch print with just 1 -v instead
    of 4.
 -- Add "no_backup_scheduling" SchedulerParameter to prevent jobs from being
    scheduled when the backup takes over. Jobs can be submitted, modified and
    cancelled while the backup is in control.
 -- Enable native Slurm backup controller to reside on an external Cray node
    when the "no_backup_scheduling" SchedulerParameter is used.
 -- Removed TICKET_BASED fairshare. Consider using the FAIR_TREE algorithm.
 -- Disable advanced reservation "REPLACE" option on IBM Bluegene systems.
 -- Add support for control distribution of tasks across cores (in addition
    to existing support for nodes and sockets, (e.g. "block", "cyclic" or
    "fcyclic" task distribution at 3 levels in the hardware rather than 2).
 -- Create db index on <cluster>_assoc_table.acct. Deleting accounts that didn't
    have jobs in the job table could take a long time.
 -- The performance of Profiling with HDF5 is improved. In addition, internal
    structures are changed to make it easier to add new profile types,
    particularly energy sensors. sh5util will continue to work with either
    format.
 -- Add partition information to sshare output if the --partition option
    is specified on the sshare command line.
 -- Add sreport -T/--tres option to identify Trackable RESources (TRES) to
    report.
 -- Display job in sacct when single step's cpus are different from the job
    allocation.
 -- Add association usage information to "scontrol show cache" command output.
 -- MPI/MVAPICH plugin now requires Munge for authentication.
 -- job_submit/lua: Add default_qos fields. Add job record qos.  Add partition
    record allow_qos and qos_char fields.

* Changes in Slurm 15.08.0pre5
==============================
 -- Add jobcomp/elasticsearch plugin. Libcurl is required for build. Configure
    the server as follows: "JobCompLoc=http://YOUR_ELASTICSEARCH_SERVER:9200".
 -- Scancel logic large re-written to better support job arrays.
 -- Added a slurm.conf parameter PrologEpilogTimeout to control how long
    prolog/epilog can run.
 -- Added TRES (Trackable resources) to track Mem, GRES, license, etc
    utilization.
 -- Add re-entrant versions of glibc time functions (e.g. localtime) to Slurm
    in order to eliminate rare deadlock of slurmstepd fork and exec calls.
 -- Constrain kernel memory (if available) in cgroups.
 -- Add PrologFlags option of "Contain" to create a proctrack container at
    job resource allocation time.
 -- Disable the OOM Killer in slurmd and slurmstepd's memory cgroup when using
    MemSpecLimit.

* Changes in Slurm 15.08.0pre4
==============================
 -- Burst_buffer/cray - Convert logic to use new commands/API names (e.g.
    "dws_setup" rather than "bbs_setup").
 -- Remove the MinJobAge size limitation. It can now exceed 65533 as it
    is represented using an unsigned integer.
 -- Verify that all plugin version numbers are identical to the component
    attempting to load them. Without this verification, the plugin can reference
    Slurm functions in the caller which differ (e.g. the underlying function's
    arguments could have changed between Slurm versions).
    NOTE: All plugins (except SPANK) must be built against the identical
    version of Slurm in order to be used by any Slurm command or daemon. This
    should eliminate some very difficult to diagnose problems due to use of old
    plugins.
 -- Increase the MAX_PACK_MEM_LEN define to avoid PMI2 failure when fencing
    with large amount of ranks (to 1GB).
 -- Requests by normal user to reset a job priority (even to lower it) will
    result in an error saying to change the job's nice value instead.
 -- SPANK naming changes: For environment variables set using the
    spank_job_control_setenv() function, the values were available in the
    slurm_spank_job_prolog() and slurm_spank_job_epilog() functions using
    getenv where the name was given a prefix of "SPANK_". That prefix has
    been removed for consistency with the environment variables available in
    the Prolog and Epilog scripts.
 -- Major additions to the layouts framework code.
 -- Add "TopologyParam" configuration parameter. Optional value of "dragonfly"
    is supported.
 -- Optimize resource allocation for systems with dragonfly networks.
 -- Add "--thread-spec" option to salloc, sbatch and srun commands. This is
    the count of threads reserved for system use per node.
 -- job_submit/lua: Enable reading and writing job environment variables.
    For example: if (job_desc.environment.LANGUAGE == "en_US") then ...
 -- Added two new APIs slurm_job_cpus_allocated_str_on_node_id()
    and slurm_job_cpus_allocated_str_on_node() to print the CPUs id
    allocated to a job.
 -- Specialized memory (a node's MemSpecLimit configuration parameter) is not
    available for allocation to jobs.
 -- Modify scontrol update job to allow jobid specification without
    the = sign. 'scontrol update job=123 ...' and 'scontrol update job 123 ...'
    are both valid syntax.
 -- Archive a month at a time when there are lots of records to archive.
 -- Introduce new sbatch option '--kill-on-invalid-dep=yes|no' which allows
    users to specify which behavior they want if a job dependency is not
    satisfied.
 -- Add Slurmdb::qos_get() interface to perl api.
 -- If a job fails to start set the requeue reason to be:
    job requeued in held state.
 -- Implemented a new MPI key,value PMIX_RING() exchange algorithm as
    an alternative to PMI2.
 -- Remove possible deadlocks in the slurmctld when the slurmdbd is busy
    archiving/purging.
 -- Add DB_ARCHIVE debug flag for filtering out debug messages in the slurmdbd
    when the slurmdbd is archiving/purging.
 -- Fix some power_save mode issues: Parsing of SuspendTime in slurm.conf was
    bad, powered down nodes would get set non-responding if there was an
    in-flight message, and permit nodes to be powered down from any state.
 -- Initialize variables in consumable resource plugin to prevent core dump.

* Changes in Slurm 15.08.0pre3
==============================
 -- CRAY - addition of acct_gather_energy/cray plugin.
 -- Add job credential to "Run Prolog" RPC used with a configuration of
    PrologFlags=alloc. This allows the Prolog to be passed identification of
    GPUs allocated to the job.
 -- Add SLURM_JOB_CONSTAINTS to environment variables available to the Prolog.
 -- Added "--mail=stage_out" option to job submission commands to notify user
    when burst buffer state out is complete.
 -- Require a "Reason" when using scontrol to set a node state to DOWN.
 -- Mail notifications on job BEGIN, END and FAIL now apply to a job array as a
    whole rather than generating individual email messages for each task in the
    job array.
 -- task/affinity - Fix memory binding to NUMA with cpusets.
 -- Display job's estimated NodeCount based off of partition's configured
    resources rather than the whole system's.
 -- Add AuthInfo option of "cred_expire=#" to specify the lifetime of a job
    step credential. The default value was changed from 1200 to 120 seconds.
 -- Set the delay time for job requeue to the job credential lifetime (120
    seconds by default). This insures that prolog runs on every node when a
    job is requeued. (This change will slow down launch of re-queued jobs).
 -- Add AuthInfo option of "cred_expire=#" to specify the lifetime of a job
    step credential.
 -- Remove srun --max-launch-time option. The option has not been functional
    since Slurm version 2.0.
 -- Add sockets and cores to TaskPluginParams' autobind option.
 -- Added LaunchParameters configuration parameter. Have srun command test
    locally for the executable file if LaunchParameters=test_exec or the
    environment variable SLURM_TEST_EXEC is set. Without this an invalid
    command will generate one error message per task launched.
 -- Fix the slurm /etc/init.d script to return 0 upon stopping the
    daemons and return 1 in case of failure.
 -- Add the ability for a compute node to be allocated to multiple jobs, but
    restricted to a single user. Added "--exclusive=user" option to salloc,
    sbatch and srun commands. Added "owner" field to node record, visible using
    the scontrol and sview commands. Added new partition configuration parameter
    "ExclusiveUser=yes|no".

* Changes in Slurm 15.08.0pre2
==============================
 -- Add the environment variables SLURM_JOB_ACCOUNT, SLURM_JOB_QOS
    and SLURM_JOB_RESERVATION in the batch/srun jobs.
 -- Add sview burst buffer display.
 -- Properly enforce partition Shared=YES option. Previously oversubscribing
    resources required gang scheduling to be configured.
 -- Enable per-partition gang scheduling resource resolution (e.g. the partition
    can have SelectTypeParameters=CR_CORE, while the global value is CR_SOCKET).
 -- Make it so a newer version of a slurmstepd can talk to an older srun.
    allocation. Nodes could have been added while waiting for an allocation.
 -- Expanded --cpu-freq parameters to include min-max:governor specifications.
    --cpu-freq now supported on salloc and sbatch.
 -- Add support for optimized job allocations with respect to SGI Hypercube
    topology.
    NOTE: Only supported with select/linear plugin.
    NOTE: The program contribs/sgi/netloc_to_topology can be used to build
    Slurm's topology.conf file.
 -- Remove 64k validation of incoming RPC nodelist size. Validated at 64MB
    when unpacking.
 -- In slurmstepd() add the user primary group if it is not part of the
    groups sent from the client.
 -- Added BurstBuffer field to advanced reservations.
 -- For advanced reservation, replace flag "License_only" with flag "Any_Nodes".
    It can be used to indicate the an advanced reservation resources (licenses
    and/or burst buffers) can be used with any compute nodes.
 -- Allow users to specify the srun --resv-ports as 0 in which case no ports
    will be reserved. The default behaviour is to allocate one port per task.
 -- Interpret a partition configuration of "Nodes=ALL" in slurm.conf as
    including all nodes defined in the cluster.
 -- Added new configuration parameters PowerParameters and PowerPlugin.
 -- Added power management plugin infrastructure.
 -- If job already exceeded one of its QOS/Accounting limits do not
    return error if user modifies QOS unrelated job settings.
 -- Added DebugFlags value of "Power".
 -- When caching user ids of AllowGroups use both getgrnam_r() and getgrent_r()
    then remove eventual duplicate entries.
 -- Remove rpm dependency between slurm-pam and slurm-devel.
 -- Remove support for the XCPU (cluster management) package.
 -- Add Slurmdb::jobs_get() interface to perl api.
 -- Performance improvement when sending data from srun to stepds when
    processing fencing.
 -- Add the feature to specify arbitrary field separator when running
    sacct -p or sacct -P. The command line option is --separator.
 -- Introduce slurm.conf parameter to use Proportional Set Size (PSS) instead
    of RSS to determinate the memory footprint of a job.
    Add an slurm.conf option not to kill jobs that is over memory limit.
 -- Add job submission command options: --sicp (available for inter-cluster
    dependencies) and --power (specify power management options) to salloc,
    sbatch, and srun commands.
 -- Add DebugFlags option of SICP (inter-cluster option logging).
 -- In order to support inter-cluster job dependencies, the MaxJobID
    configuration parameter default value has been reduced from 4,294,901,760
    to 2,147,418,112 and it's maximum value is now 2,147,463,647.
    ANY JOBS WITH A JOB ID ABOVE 2,147,463,647 WILL BE PURGED WHEN SLURM IS
    UPGRADED FROM AN OLDER VERSION!
 -- Add QOS name to the output of a partition in squeue/scontrol/sview/smap.

* Changes in Slurm 15.08.0pre1
==============================
 -- Add sbcast support for file transfer to resources allocated to a job step
    rather than a job allocation.
 -- Change structures with association in them to assoc to save space.
 -- Add support for job dependencies jointed with OR operator (e.g.
    "--depend=afterok:123?afternotok:124").
 -- Add "--bb" (burst buffer specification) option to salloc, sbatch, and srun.
 -- Added configuration parameters BurstBufferParameters and BurstBufferType.
 -- Added burst_buffer plugin infrastructure (needs many more functions).
 -- Make it so when the fanout logic comes across a node that is down we abandon
    the tree to avoid worst case scenarios when the entire branch is down and
    we have to try each serially.
 -- Add better error reporting of invalid partitions at submission time.
 -- Move will-run test for multiple clusters from the sbatch code into the API
    so that it can be used with DRMAA.
 -- If a non-exclusive allocation requests --hint=nomultithread on a
    CR_CORE/SOCKET system lay out tasks correctly.
 -- Avoid including unused CPUs in a job's allocation when cores or sockets are
    allocated.
 -- Added new job state of STOPPED indicating processes have been stopped with a
    SIGSTOP (using scancel or sview), but retain its allocated CPUs. Job state
    returns to RUNNING when SIGCONT is sent (also using scancel or sview).
 -- Added EioTimeout parameter to slurm.conf. It is the number of seconds srun
    waits for slurmstepd to close the TCP/IP connection used to relay data
    between the user application and srun when the user application terminates.
 -- Remove slurmctld/dynalloc plugin as the work was never completed, so it is
    not worth the effort of continued support at this time.
 -- Remove DynAllocPort configuration parameter.
 -- Add advance reservation flag of "replace" that causes allocated resources
    to be replaced with idle resources. This maintains a pool of available
    resources that maintains a constant size (to the extent possible).
 -- Added SchedulerParameters option of "bf_busy_nodes". When selecting
    resources for pending jobs to reserve for future execution (i.e. the job
    can not be started immediately), then preferentially select nodes that are
    in use. This will tend to leave currently idle resources available for
    backfilling longer running jobs, but may result in allocations having less
    than optimal network topology. This option is currently only supported by
    the select/cons_res plugin.
 -- Permit "SuspendTime=NONE" as slurm.conf value rather than only a numeric
    value to match "scontrol show config" output.
 -- Add the 'scontrol show cache' command which displays the associations
    in slurmctld.
 -- Test more frequently for node boot completion before starting a job.
    Provides better responsiveness.
 -- Fix PMI2 singleton initialization.
 -- Permit PreemptType=qos and PreemptMode=suspend,gang to be used together.
    A high-priority QOS job will now oversubscribe resources and gang schedule,
    but only if there are insufficient resources for the job to be started
    without preemption. NOTE: That with PreemptType=qos, the partition's
    Shared=FORCE:# configuration option will permit one job more per resource
    to be run than than specified, but only if started by preemption.
 -- Remove the CR_ALLOCATE_FULL_SOCKET configuration option.  It is now the
    default.
 -- Fix a race condition in PMI2 when fencing counters can be out of sync.
 -- Increase the MAX_PACK_MEM_LEN define to avoid PMI2 failure when fencing
    with large amount of ranks.
 -- Add QOS option to a partition.  This will allow a partition to have
    all the limits a QOS has.  If a limit is set in both QOS the partition
    QOS will override the job's QOS unless the job's QOS has the
    OverPartQOS flag set.
 -- The task_dist_states variable has been split into "flags" and "base"
    components. Added SLURM_DIST_PACK_NODES and SLURM_DIST_NO_PACK_NODES values
    to give user greater control over task distribution. The srun --dist options
    has been modified to accept a "Pack" and "NoPack" option. These options can
    be used to override the CR_PACK_NODE configuration option.

* Changes in Slurm 14.11.12
===========================
 -- Correct dependency formatting to print array task ids if set.
 -- Fix for configuration of "AuthType=munge" and "AuthInfo=socket=..." with
    alternate munge socket path.
 -- BGQ - Remove redeclaration of job_read_lock.
 -- BGQ - Tighter locks around structures when nodes/cables change state.
 -- Fix job array formatting to allow return [0-100:2] display for arrays with
    step functions rather than [0,2,4,6,8,...] .
 -- Associations - prevent hash table corruption if uid initially unset for
    a user, which can cause slurmctld to crash if that user is deleted.
 -- Add cast to memory limit calculation to prevent integer overflow for
    very large memory values.
 -- Fix test cases to have proper int return signature.

* Changes in Slurm 14.11.11
===========================
 -- Fix systemd's slurmd service from killing slurmstepds on shutdown.
 -- Fix the qstat wrapper when user is removed from the system but still
    has running jobs.
 -- Log the request to terminate a job at info level if DebugFlags includes
    the Steps keyword.
 -- Fix potential memory corruption in _slurm_rpc_epilog_complete as well as
    _slurm_rpc_complete_job_allocation.
 -- Fix incorrectly sized buffer used by jobid2str which will cause buffer
    overflow in slurmctld. (Bug 2295.)

* Changes in Slurm 14.11.10
===========================
 -- Fix truncation of job reason in squeue.
 -- If a node is in DOWN or DRAIN state, leave it unavailable for allocation
    when powered down.
 -- Update the slurm.conf man page documenting better nohold_on_prolog_fail
    variable.
 -- Don't trucate task ID information in "squeue --array/-r" or "sview".
 -- Fix a bug which caused scontrol to core dump when releasing or
    holding a job by name.
 -- Fix unit conversion bug in slurmd which caused wrong memory calculation
    for cgroups.
 -- Fix issue with GRES in steps so that if you have multiple exclusive steps
    and you use all the GRES up instead of reporting the configuration isn't
    available you hold the requesting step until the GRES is available.
 -- Fix slurmdbd backup to use DbdAddr when contacting the primary.
 -- Fix error in MPI documentation.
 -- Fix to handle arrays with respect to number of jobs submitted.  Previously
    only 1 job was accounted (against MaxSubmitJob) for when an array was
    submitted.
 -- Correct counting for job array limits, job count limit underflow possible
    when master cancellation of master job record.
 -- For pending jobs have sacct print 0 for nnodes instead of the bogus 2.
 -- Fix for tracking node state when jobs that have been allocated exclusive
    access to nodes (i.e. entire nodes) and later relinquish some nodes. Nodes
    would previously appear partly allocated and prevent use by other jobs.
 -- Fix updating job in db after extending job's timelimit past partition's
    timelimit.
 -- Fix srun -I<timeout> from flooding the controller with step create requests.
 -- Requeue/hold batch job launch request if job already running (possible if
    node went to DOWN state, but jobs remained active).
 -- If a job's CPUs/task ratio is increased due to configured MaxMemPerCPU,
    then increase it's allocated CPU count in order to enforce CPU limits.
 -- Don't mark powered down node as not responding. This could be triggered by
    race condition of the node suspend and ping logic.
 -- Don't requeue RPC going out from slurmctld to DOWN nodes (can generate
    repeating communication errors).
 -- Propagate sbatch "--dist=plane=#" option to srun.
 -- Fix sacct to not return all jobs if the -j option is given with a trailing
    ','.
 -- Permit job_submit plugin to set a job's priority.
 -- Fix occasional srun segfault.
 -- Fix issue with sacct, printing 0_0 for array's that had finished in the
    database but the start record hadn't made it yet.
 -- Fix sacct -j, (nothing but a comma) to not return all jobs.
 -- Prevent slurmstepd from core dumping if /proc/<pid>/stat has
    unexpected format.

* Changes in Slurm 14.11.9
==========================
 -- Correct "sdiag" backfill cycle time calculation if it yields locks. A
    microsecond value was being treated as a second value resulting in an
    overflow in the calcuation.
 -- Fix segfault when updating timelimit on jobarray task.
 -- Fix to job array update logic that can result in a task ID of 4294967294.

 -- Prevent job array task ID being inappropriately set to NO_VAL.
 -- MYSQL - Make it so you don't have to restart the slurmctld
    to gain the correct limit when a parent account is root and you
    remove a subaccount's limit which exists on the parent account.
 -- MYSQL - Close chance of setting the wrong limit on an association
    when removing a limit from an association on multiple clusters
    at the same time.
 -- MYSQL - Fix minor memory leak when modifying an association but no
    change was made.
 -- srun command line of either --mem or --mem-per-cpu will override both the
    SLURM_MEM_PER_CPU and SLURM_MEM_PER_NODE environment variables.
 -- Prevent slurmctld abort on update of advanced reservation that contains no
    nodes.
 -- ALPS - Revert commit 2c95e2d22 which also removes commit 2e2de6a4 allowing
    cray with the SubAllocate option to work as it did with 2.5.
 -- Properly parse CPU frequency data on POWER systems.
 -- Correct sacct.a man pages describing -i option.
 -- Capture salloc/srun information in sdiag statistics.
 -- Fix bug in node selection with topology optimization.
 -- Don't set distribution when srun requests 0 memory.
 -- Read in correct number of nodes from SLURM_HOSTFILE when specifying nodes
    and --distribution=arbitrary.
 -- Fix segfault in Bluegene setups where RebootQOSList is defined in
    bluegene.conf and accounting is not setup.
 -- MYSQL - Update mod_time when updating a start job record or adding one.
 -- MYSQL - Fix issue where if an association id ever changes on at least a
    portion of a job array is pending after it's initial start in the
    database it could create another row for the remain array instead
    of using the already existing row.
 -- Fix scheduling anomaly with job arrays submitted to multiple partitions,
    jobs could be started out of priority order.
 -- If a host has suspened jobs do not reboot it. Reboot only hosts
    with no jobs in any state.
 -- ALPS - Fix issue when using --exclusive flag on srun to do the correct
    thing (-F exclusive) instead of -F share.
 -- Fix various memory leaks in the Perl API.
 -- Fix a bug in the controller which display jobs in CF state as RUNNING.
 -- Preserve advanced _core_ reservation when nodes added/removed/resized on
    slurmctld restart. Rebuild core_bitmap as needed.
 -- Fix for non-standard Munge port location for srun/pmi use.

 -- Sort job arrays in job queue according to array_task_id when priorities are
    equal.
 -- Fix segfault in sreport when there was no response from the dbd.
 -- ALPS - Fix compile to not link against -ljob and -lexpat with every lib
    or binary.
 -- Fix testing for CR_Memory when CR_Memory and CR_ONE_TASK_PER_CORE are used
    with select/linear.
 -- MySQL - Fix minor memory leak if a connection ever goes away whist using it.
 -- ALPS - Make it so srun --hint=nomultithread works correctly.

    array gets requeued.
 -- Fix some potential deadlock issues when state files don't exist in the
    association manager.
 -- Correct RebootProgram logic when executed outside of a maintenance
    reservation.
 -- Requeue job if possible when slurmstepd aborts.

* Changes in Slurm 14.11.8
==========================
 -- Eliminate need for user to set user_id on job_update calls.
 -- Correct list of unavailable nodes reported in a job's "reason" field when
    that job can not start.
 -- Map job --mem-per-cpu=0 to --mem=0.
 -- Fix squeue -o %m and %d unit conversion to Megabytes.
 -- Fix issue with incorrect time calculation in the priority plugin when
    a job runs past it's time limit.

 -- When deleting a job from the system set the job_id to 0 to avoid memory
    corruption if thread uses the pointer basing validity off the id.
 -- Fix issue where sbatch would set ntasks-per-node to 0 making any srun
    afterward cause a divide by zero error.
 -- switch/cray: Refine logic to set PMI_CRAY_NO_SMP_ENV environment variable.
 -- When sacctmgr loads archives with version less than 14.11 set the array
    task id to NO_VAL, so sacct can display the job ids correctly.
 -- When using memory cgroup if a task uses more memory than requested
    the failures are logged into memory.failcnt count file by cgroup
    and the user is notified by slurmstepd about it.
 -- Fix scheduling inconsistency with GRES bound to specific CPUs.
 -- If user belongs to a group which has split entries in /etc/group
    search for its username in all groups.
 -- Do not consider nodes explicitly powered up as DOWN with reason of "Node
    unexpected rebooted".
 -- Use correct slurmd spooldir when creating cpu-frequency locks.
 -- Note that TICKET_BASED fairshare will be deprecated in the future. Consider
    using the FAIR_TREE algorithm instead.
 -- Set job's reason to BadConstaints when job can't run on any node.
 -- Prevent abort on update of reservation with no nodes (licenses only).
 -- Prevent slurmctld from dumping core if job_resrcs is missing in the
    job data structure.
 -- Fix squeue to print array task ids according to man page when
    SLURM_BITSTR_LEN is defined in the environment.
 -- In squeue, sort jobs based on array job ID if available.
 -- Fix the calculation of job energy by not including the NO_VAL values.
 -- Advanced reservation fixes: enable update of bluegene reservation, avoid
    abort on multi-core reservations.
 -- Set the totalview_stepid to the value of the job step instead of NO_VAL.
 -- Fix slurmdbd core dump if the daemon does not have connection with
    the database.
 -- Display error message when attempting to modify priority of a held job.
 -- Backfill scheduler: The configured backfill_interval value (default 30
    seconds) is now interpretted as a maximum run time for the backfill
    scheduler. Once reached, the scheduler will build a new job queue and
    start over, even if not all jobs have been tested.
 -- Backfill scheduler now considers OverTimeLimit and KillWait configuration
    parameters to estimate when running jobs will exit.
 -- Correct task layout with CR_Pack_Node option and more than 1 CPU per task.
 -- Fix the scontrol man page describing the release argument.
 -- When job QOS is modified, do so before attempting to change partition in
    order to validate the partition's Allow/DenyQOS parameter.

* Changes in Slurm 14.11.7
==========================
 -- Initialize some variables used with the srun --no-alloc option that may
    cause random failures.
 -- Add SchedulerParameters option of sched_min_interval that controls the
    minimum time interval between any job scheduling action. The default value
    is zero (disabled).
 -- Change default SchedulerParameters=max_sched_time from 4 seconds to 2.
 -- Refactor scancel so that all pending jobs are cancelled before starting
    cancellation of running jobs. Otherwise they happen in parallel and the
    pending jobs can be scheduled on resources as the running jobs are being
    cancelled.
 -- ALPS - Add new cray.conf variable NoAPIDSignalOnKill.  When set to yes this
    will make it so the slurmctld will not signal the apid's in a batch job.
    Instead it relies on the rpc coming from the slurmctld to kill the job to
    end things correctly.
 -- ALPS - Have the slurmstepd running a batch job wait for an ALPS release
    before ending the job.
 -- Initialize variables in consumable resource plugin to prevent core dump.
 -- Fix scancel bug which could return an error on attempt to signal a job step.
 -- In slurmctld communication agent, make the thread timeout be the configured
    value of MessageTimeout rather than 30 seconds.
 -- sshare -U/--Users only flag was used uninitialized.
 -- Cray systems, add "plugstack.conf.template" sample SPANK configuration file.
 -- BLUEGENE - Set DB2NOEXITLIST when starting the slurmctld daemon to avoid
    random crashing in db2 when the slurmctld is exiting.
 -- Make full node reservations display correctly the core count instead of
    cpu count.
 -- Preserve original errno on execve() failure in task plugin.
 -- Add SLURM_JOB_NAME env variable to an salloc's environment.
 -- Overwrite SLURM_JOB_NAME in an srun when it gets an allocation.
 -- Make sure each job has a wckey if that is something that is tracked.
 -- Make sure old step data is cleared when job is requeued.
 -- Load libtinfo as needed when building ncurses tools.
 -- Fix small memory leak in backup controller.
 -- Fix segfault when backup controller takes control for second time.
 -- Cray - Fix backup controller running native Slurm.
 -- Provide prototypes for init_setproctitle()/fini_setproctitle on NetBSD.
 -- Add configuration test to find out the full path to su command.
 -- preempt/job_prio plugin: Fix for possible infinite loop when identifying
    preemptable jobs.
 -- preempt/job_prio plugin: Implement the concept of Warm-up Time here. Use
    the QoS GraceTime as the amount of time to wait before preempting.
    Basically, skip preemption if your time is not up.
 -- Make srun wait KillWait time when a task is cancelled.
 -- switch/cray: Revert logic added to 14.11.6 that set "PMI_CRAY_NO_SMP_ENV=1"
    if CR_PACK_NODES is configured.

* Changes in Slurm 14.11.6
==========================
 -- If SchedulerParameters value of bf_min_age_reserve is configured, then
    a newly submitted job can start immediately even if there is a higher
    priority non-runnable job which has been waiting for less time than
    bf_min_age_reserve.
 -- qsub wrapper modified to export "all" with -V option
 -- RequeueExit and RequeueExitHold configuration parameters modified to accept
    numeric ranges. For example "RequeueExit=1,2,3,4" and "RequeueExit=1-4" are
    equivalent.
 -- Correct the job array specification parser to accept brackets in job array
    expression (e.g. "123_[4,7-9]").
 -- Fix for misleading job submit failure errors sent to users. Previous error
    could indicate why specific nodes could not be used (e.g. too small memory)
    when other nodes could be used, but were not for another reason.
 -- Fix squeue --array to display correctly the array elements when the
    % separator is specified at the array submission time.
 -- Fix priority from not being calculated correctly due to memory issues.
 -- Fix a transient pending reason 'JobId=job_id has invalid QOS'.
 -- A non-administrator change to job priority will not be persistent except
    for holding the job. User's wanting to change a job priority on a persistent
    basis should reset it's "nice" value.
 -- Print buffer sizes as unsigned values when failed to pack messages.
 -- Fix race condition where sprio would print factors without weights applied.
 -- Document the sacct option JobIDRaw which for arrays prints the jobid instead
    of the arrayTaskId.
 -- Allow users to modify MinCPUsNode, MinMemoryNode and MinTmpDiskNode of
    their own jobs.
 -- Increase the jobid print field in SQUEUE_FORMAT in
    opt_modulefiles_slurm.in.
 -- Enable compiling without optimizations and with debugging symbols by
    default. Disable this by configuring with --disable-debug.
 -- job_submit/lua plugin: Add mail_type and mail_user fields.
 -- Correct output message from sshare.
 -- Use standard statvfs(2) syscall if available, in preference to
    non-standard statfs.
 -- Add a new option -U/--Users to sshare to display only users
    information, parent and ancestors are not printed.
 -- Purge 50000 records at a time so that locks can released periodically.
 -- Fix potentially uninitialized variables
 -- ALPS - Fix issue where a frontend node could become unresponsive and never
    added back into the system.
 -- Gate epilog complete messages as done with other messages
 -- If we have more than a certain number of agents (50) wait longer when gating
    rpcs.
 -- FrontEnd - ping non-responding or down nodes.
 -- switch/cray: If CR_PACK_NODES is configured, then set the environment
    variable "PMI_CRAY_NO_SMP_ENV=1"
 -- Fix invalid memory reference in SlurmDBD when putting a node up.
 -- Allow opening of plugstack.conf even when a symlink.
 -- Fix scontrol reboot so that rebooted nodes will not be set down with reason
    'Node xyz unexpectedly rebooted' but will be correctly put back to service.
 -- CRAY - Throttle the post NHC operations as to not hog the job write lock
    if many steps/jobs finish at once.
 -- Disable changes to GRES count while jobs are running on the node.
 -- CRAY - Fix issue with scontrol reconfig.
 -- slurmd: Remove wrong reporting of "Error reading step  ... memory limit".
    The logic was treating success as an error.
 -- Eliminate "Node ping apparently hung" error messages.
 -- Fix average CPU frequency calculation.
 -- When allocating resources with resolution of sockets, charge the job for all
    CPUs on allocated sockets rather than just the CPUs on used cores.
 -- Prevent slurmdbd error if cluster added or removed while rollup in progress.
    Removing a cluster can cause slurmdbd to abort. Adding a cluster can cause
    the slurmdbd rollup to hang.
 -- sview - When right clicking on a tab make sure we don't display the page
    list, but only the column list.
 -- FRONTEND - If doing a clean start make sure the nodes are brought up in the
    database.
 -- MySQL - Fix issue when using the TrackSlurmctldDown and nodes are down at
    the same time, don't double bill the down time.
 -- MySQL - Various memory leak fixes.
 -- sreport - Fix Energy displays
 -- Fix node manager logic to keep unexpectedly rebooted node in state
    NODE_STATE_DOWN even if already down when rebooted.
 -- Fix for array jobs submitted to multiple partitions not starting.
 -- CRAY - Enable ALPs mpp compatibility code in sbatch for native Slurm.
 -- ALPS - Move basil_inventory to less confusing function.
 -- Add SchedulerParameters option of "sched_max_job_start="  to limit the
    number of jobs that can be started in any single execution of the main
    scheduling logic.
 -- Fixed compiler warnings generated by gcc version >= 4.6.
 -- sbatch to stop parsing script for "#SBATCH" directives after first command,
    which matches the documentation.
 -- Overwrite the SLURM_JOB_NAME in sbatch if already exist in the environment
    and use the one specified on the command line --job-name.
 -- Remove xmalloc_nz from unpack functions.  If the unpack ever failed the
    free afterwards would not have zeroed out memory on the variables that
    didn't get unpacked.
 -- Improve database interaction from controller.
 -- Fix for data shift when loading job archives.
 -- ALPS - Added new SchedulerParameters=inventory_interval to specify how
    often an inventory request is handled.
 -- ALPS - Don't run a release on a reservation on the slurmctld for a batch
    job.  This is already handled on the stepd when the script finishes.

* Changes in Slurm 14.11.5
==========================
 -- Correct the squeue command taking into account that a node can
    have NULL name if it is not in DNS but still in slurm.conf.
 -- Fix slurmdbd regression which would cause a segfault when a node is set
    down with no reason.

    just one since the batch step has access to all CPUs like other steps.
 -- Fix job getting EligibleTime set before meeting dependency requirements.
 -- Correct the initialization of QOS MinCPUs per job limit.
 -- Set the debug level of information messages in cgroup plugin to debug2.
 -- For job running under a debugger, if the exec of the task fails, then
    cancel its I/O and abort immediately rather than waiting 60 seconds for
    I/O timeout.
 -- Fix associations not getting default qos set until after a restart.
 -- Set the value of total_cpus not to be zero before invoking
    acct_policy_job_runnable_post_select.
 -- MySQL - When requesting cluster resources, only return resources for the
    cluster(s) requested.
 -- Add TaskPluginParam=autobind=threads option to set a default binding in the
    case that "auto binding" doesn't find a match.
 -- Introduce a new SchedulerParameters variable nohold_on_prolog_fail.
    If configured don't requeue jobs on hold is a Prolog fails.
 -- Make it so sched_params isn't read over and over when an epilog complete
    message comes in

 -- Cray - Add ALPS_APP_ID_ENV environment variable.
 -- Increase maximum MaxArraySize configuration parameter value from 1,000,001
    to 4,000,001.
 -- Added new SchedulerParameters value of bf_min_age_reserve. The backfill
    scheduler will not reserve resources for pending jobs until they have
    been pending for at least the specified number of seconds. This can be
    valuable if jobs lack time limits or all time limits have the same value.
 -- Fix support for --mem=0 (all memory of a node) with select/cons_res plugin.
 -- Fix bug that can permit someone to kill job array belonging to another user.
 -- Don't set the default partition on a license only reservation.
 -- Show a NodeCnt=0, instead of NO_VAL, in "scontrol show res" for a license

    CUDA_VISIBLE_DEVICES will start at 0 rather than the device number.
 -- Fix job array logic that can cause slurmctld to abort.
 -- Report job "shared" field properly in scontrol, squeue, and sview.
 -- If a job is requeued because of RequeueExit or RequeueExitHold sent event
    REQUEUED to slurmdbd.
 -- Fix build if hwloc is in non-standard location.
 -- Fix slurmctld job recovery logic which could cause the last task in a job
    array to be lost.
