This file describes changes in recent versions of SLURM. It primarily
documents those changes that are of interest to users and admins.
* Changes in SLURM 2.2.0.rc3
============================
* Changes in SLURM 2.2.0.rc2
============================
-- Fix memory leak in job step allocation logic. Patch from Hongjia Cao, NUDT.
-- If a preempted job was submitted with the --no-requeue option then cancel
rather than requeue it.
Danny Auble
committed
-- Fix for problems when adding a user for the first time to a new cluster
with a 2.1 sacctmgr without specifying a default account.
-- Resend TERMINATE_JOB message only to nodes that the job still has not
terminated on. Patch from Hongjia Cao, NUDT.
-- Treat time limit specification of "0:300" as a request for 300 seconds
(5 minutes) instead of one minute.
-- Modify sched/backfill plugin logic to continue working its way down the
queue of jobs rather than restarting at the top if there are no changes in
job, node, or partition state between runs. Patch from Hongjia Cao, NUDT.
-- Improve scalability of select/cons_res logic. Patch from Matthieu Hautreux,
CEA.
Danny Auble
committed
-- Fix for possible deadlock in the slurmstepd when cancelling a job that is
also writing a large amount of data to stderr.
-- Fix in select/cons_res to eliminate "mem underflow" error when the
slurmctld is reconfigured while a job is in completing state.
-- Send a message to the a user's job when it's real or virual memory limit
is exceeded. :
Danny Auble
committed
-- Apply rlimits right before execing the users task so to lower the risk of
the task exiting because the slurmstepd ran over a limit (log file size,
etc.)
-- Add scontrol command of "uhold <job_id>" so that an administrator can hold
a job and let the job's owner release it. The scontrol command of
"hold <job_id>" when executed by a SLURM administrator can only be released
by a SLURM administrator and not the job owner.
-- Change atoi to slurm_atoul in mysql plugin, needed for running on 32-bit
systems in some cases.
-- If a batch job is found to be missing from a node, make its termination
state be NODE_FAIL rather than CANCELLED.
Danny Auble
committed
-- Fatal error put back if running a bluegene or cray plugin from a controller
not of that type.
Danny Auble
committed
-- Make sure jobacct_gather plugin is not shutdown before messing with the
proccess list.
-- Modify signal handling in srun and salloc commands to deadlock if the
malloc function is interupted and called again. The malloc function is
thread safe, but not reentrant, which is a problem when signal handling if
the malloc function itself has a lock.
-- In srun set job abort flag on completion to handle the case when a user
cancels a job while the node is not responding but slurmctld has not yet
the node down. Patch from Hongjia Cao, NUDT.
-- Streamline the PMI logic if no duplicate keys are included in the key-pairs
managed. Substantially improves performance for large numbers of tasks.
Adds support for SLURM_PMI_KVS_NO_DUP_KEYS environment variable. Patch
from Hongjia Cao, NUDT.
Danny Auble
committed
-- Fix issues with sview dealing with older versions of sview and saving
defaults.
-- Remove references to --mincores, --minsockets, and --minthreads from the
salloc, sbatch and srun man pages. These options are defunct, Patch from
Rod Schultz, Bull.
Danny Auble
committed
-- Made openssl not be required to build RPMs, it is not required anymore
since munge is the default crypto plugin.
Danny Auble
committed
-- sacctmgr now has smarts to figure out if a qos is a default qos when
modifing a user/acct or removing a qos.
-- For reservations on BlueGene systems, set and report c-node counts rather
than midplane counts.
* Changes in SLURM 2.2.0.rc1
============================
-- Add show_flags parameter to the slurm_load_block_info() function.
-- perlapi has been brought up to speed courtesy of Hongjia Coa. (make sure to
run 'make clean' if building in a different dir than source)
-- Fixed regression in pre12 in crypto/munge when running with
--enable-multiple-slurmd which would cause the slurmd's to core.
-- Fixed regression where cpu count wasn't figured out correctly for steps.
-- Fixed issue when using old mysql that can't handle a '.' in the table
name.
-- Mysql plugin works correctly without the SlurmDBD
Danny Auble
committed
-- Added ability to query batch step with sstat. Currently no accounting data
is stored for the batch step, but the internals are inplace if we decide to
do that in the future.
-- Fixed some backwards compatibility issues with 2.2 talking to 2.1.
Danny Auble
committed
-- Fixed regression where modifying associations didn't get sent to the
slurmctld.
-- Made sshare sort things the same way saccmgr list assoc does
(alphabetically)
-- Fixed issue with default accounts being set up correctly.
Danny Auble
committed
-- Changed sortting in the slurmctld so sshare output is similar to that of
sacctmgr list assoc.
-- Modify reservation logic so that daily and weekly reservations maintain
the same time when daylight savings time starts or ends in the interim.
-- Edit to make reservations handle updates to associations.
-- Added the derived exit code to the slurmctld job record and the derived
exit code and string to the job record in the SLURM db.
-- Added slurm-sjobexit RPM for SLURM job exit code management tools.
-- Added ability to use sstat/sacct against the batch step.
-- Added OnlyDefaults option to sacctmgr list associations.
-- Modified the fairshare priority formula to F = 2**(-Ue/S)
-- Modify the PMI functions key-pair exchange function to support a 32-bit
counter for larger job sizes. Patch from Hongjia Cao, NUDT.
-- In sched/builtin - Make the estimated job start time logic faster (borrowed
new logic from sched/backfill and added pthread) and more accurate.
-- In select/cons_res fix bug that could result in a job being allocated zero
CPUs on some nodes. Patch from Hongjia Cao, NUDT.
-- Fix bug in sched/backfill that could set expected start time of a job too
far in the future.
Danny Auble
committed
-- Added ability to enforce new limits given to associations/qos on
pending jobs.
-- Increase max message size for the slurmdbd from 1000000 to 16*1024*1024
-- Increase number of active threads in the slurmdbd from 50 to 100
-- Fixed small bug in src/common/slurmdb_defs.c reported by Bjorn-Helge Mevik

-- Fixed sview show config on non-bluegene systems.
-- Fixed bug in selecting jobs based on sacct -N option
-- Fix bug that prevented job Epilog from running more than once on a node if
a job was requeued and started no job steps.
-- Fixed issue where node index wasn't stored correcting when using DBD.
-- Enable srun's use of the --nodes option with --exclusive (previously the
--nodes option was ignored).
-- Added UsageThreshold and Flags to the QOS object.
-- Patch to improve threadsafeness in the mysql plugins.
-- Add support for fair-share scheduling to be based upon resource use at
the level of bank accounts and ignore use of individual users. Patch by
Par Andersson, National Supercomputer Centre, Sweden.
* Changes in SLURM 2.2.0.pre12
==============================
-- Log if Prolog or Epilog run for longer than MessageTimeout / 2.
-- Log the RPC number associated with messages from slurmctld that timeout.
-- Fix bug in select/cons_res logic when job allocation includes --overcommit
and --ntasks-per-node options and the node has fewer CPUs than the count
specified by --ntasks-per-node.
-- Fix bug in gang scheduling and job preemption logic so that preempted jobs
get resumed properly after a slurmctld hot-start.
-- Fix bug in select/linear handling of gang scheduled jobs that could result
in run_job_cnt underflow error message.
-- Fix bug in gang scheduling logic to properly support partitions added
using the scontrol command.
-- Fix a segmentation fault in sview where the 'excluded_partitions' field
was set to NULL, caused by the absence of ~/.slurm/sviewrc.
-- Rewrote some calls to is_user_any_coord() in src/plugins/accounting_storage
modules to make use of is_user_any_coord()'s return value.
-- Add configure option of --with=dimensions=#.
-- Modify srun ping logic so that srun would only be considered not responsive
if three ping messages were not responded to. Patch from Hongjia Cao (NUDT).
-- Preserve a node's ReasonTime field after scontrol reconfig command. Patch
from Hongjia Cao (NUDT).
-- Added the authority for users with AdminLevel's defined in the SLURM db
(Operators and Admins) and account coordinators to invoke commands that
affect jobs, reservations, nodes, etc.
-- Fix for slurmd restart on completing node with no tasks to get the correct
state, completing. Patch from Hongjia Cao (NUDT).
-- Prevent scontrol setting a node's Reason="". Patch from Hongjia Cao (NUDT).
-- Add new functions hostlist_ranged_string_malloc,
hostlist_ranged_string_xmalloc, hostlist_deranged_string_malloc, and
hostlist_deranged_string_xmalloc which will allocate memory as needed.
-- Make the slurm commands support both the --cluster and --clusters option.
Previously, some commands support one of those options, but not the other.
-- Fix bug when resizing a job that has steps running on some of those nodes.
Avoid killing the job step on remaining nodes. Patch from Rod Schultz
(BULL). Also fix bug related to tracking the CPUs allocated to job steps
on each node after releasing some nodes from the job's allocation.
-- Applied patch from Rod Schultz / Matthieu Hautreux to keep the Node-to-Host
cache from becoming corrupted when a hostname cannot be resolved.
-- Export more symbols in libslurm for job and node state information
translation (numbers to strings). Patch from Hongia Cao, NUDT.
-- Add logic to retry sending RESPONSE_LAUNCH_TASKS messages from slurmd to
srun. Patch from Hongia Cao, NUDT.
-- Modify bit_unfmt_hexmask() and bit_unfmt_binmask() functions to clear the
bitmap input before setting the bits indicated in the input string.
-- Add SchedulerParameters option of bf_window to control how far into the
future that the backfill scheduler will look when considering jobs to start.
The default value is one day. See "man slurm.conf" for details.
-- Fix bug that can result in duplicate job termination records in accounting
for job termination when slurmctld restarts or reconfigures.
-- Modify plugin and library logic as needed to support use of the function
slurm_job_step_stat() from user commands.
-- Fix race condition in which PrologSlurmctld failure could cause slurmctld
to abort.
-- Fix bug preventing users in secondary user groups from being granted access
to partitions configured with AllowGroups.
-- Added support for a default account and wckey per cluster within accounting.
-- Modified select/cons_res plugin so that if MaxMemPerCPU is configured and a
job specifies it's memory requirement, then more CPUs than requested will
automatically be allocated to a job to honor the MaxMemPerCPU parameter.
-- Added the derived_ec (exit_code) member to job_info_t. exit_code captures
the exit code of the job script (or salloc) while derived_ec contains the
highest exit code of all the job steps.
-- Added SLURM_JOB_EXIT_CODE and SLURM_JOB_DERIVED_EC variables to the
EpilogSlurmctld environment

-- Add locks around the MySQL calls for proper operation if the non-thread
safe version of the MySQL library is used.
-- Remove libslurm.a, libpmi.a and libslurmdb.a from SLURM RPM. These static
libraries are not generally usable.
-- Fixed bug in sacctmgr when zeroing raw usage reported by Gerrit Renker.
* Changes in SLURM 2.2.0.pre11
==============================
-- Permit a regular user to change the partition of a pending job.
-- Major re-write of the job_submit/lua plugin to pass pointers to available
partitions and use lua metatables to reference the job and partition fields.
-- Add support for serveral new trigger types: SlurmDBD failure/restart,
Database failure/restart, Slurmctld failure/restart.
-- Add support for SLURM_CLUSTERS environment variable in the sbatch, sinfo,
squeue commands.
-- Modify the sinfo and squeue commands to report state of multiple clusters
if the --clusters option is used.
-- Added printf __attribute__ qualifiers to info, debug, ... to help prevent
bad/incorrect parameters being sent to them. Original patch from
-- Fix bug in slurmctld job completion logic when nodes allocated to a
completing job are re-booted. Patch from Hongjia Cao (NUDT).

"node_rank".
-- Add topology/node_rank plugin to sort nodes based upon rank loaded from
BASIL on Cray computers.
-- Fix memory leak in the auth/munge and crypto/munge plugins in the case of
some failure modes.
* Changes in SLURM 2.2.0.pre10
==============================
Danny Auble
committed
-- Fix issue when EnforcePartLimits=yes in slurm.conf all jobs where no nodecnt
was specified the job would be seen to have maxnodes=0 which would not
allow jobs to run.
Danny Auble
committed
-- Fix issue where if not suspending a job the gang scheduler does the correct
kill procedure.
Danny Auble
committed
-- Fixed some issues when dealing with jobs from a 2.1 system so they live
after an upgrade.
-- In srun, log if --cpu_bind options are specified, but not supported by the
current system configuration.
Danny Auble
committed
-- Various Patchs from Hongjia Cao dealing with bugs found in sacctmgr and
the slurmdbd.
-- Fix bug in changing the nodes allocated to a running job and some node
names specified are invalid, avoid invalid memory reference.
-- Fixed filename substitution of %h and %n based on patch from Ralph Bean
-- Added better job sorting logic when preempting jobs with qos.
-- Log the IP address and port number for some communication errors.
-- Fix bug in select/cons_res when --cpus_per_task option is used, could
oversubscribe resources.
-- In srun, do not implicitly set the job's maximum node count based upon a
required hostlist.
-- Avoid running the HealthCheckProgram on non-responding nodes rather than
DOWN nodes.
-- Fix bug in handling of poll() functions on OS X (SLURM was ignoring POLLIN
if POLLHUP flag was set at the same time).
Danny Auble
committed
-- Pulled Cray logic out of common/node_select.c into it's own
select/cray plugin cons_res is the default. To use linear add 'Linear' to
SelectTypeParameters.
-- Fixed bug where resizing jobs didn't correctly set used limits correctly.
-- Change sched/backfill default time interval to 30 seconds and defer attempt
to backfill schedule if slurmctld has more than 5 active RPCs. General
improvements in logic scalability.
-- Add SchedulerParameters option of default_sched_depth=# to control how
many jobs on queue should be tested for attempted scheduling when a job
completes or other routine events. Default value is 100 jobs. The full job
queue is tested on a less frequent basis. This option can dramatically
improve performance on systems with thousands of queued jobs.
-- Gres/gpu now sets the CUDA_VISIBLE_DEVICES environment to control which
GPU devices should be used for each job or job step and CUDA version 3.1+
is used. NOTE: SLURM's generic resource support is still under development.
-- Modify select/cons_res to pack jobs onto allocated nodes differently and
Moe Jette
committed
minimize system fragmentation. For example on nodes with 8 CPUs each, a
job needing 10 CPUs will now ideally be allocated 8 CPUs on one node and
2 CPUs on another node. Previously the job would have ideally been
allocated 5 CPUs on each node, fragmenting the unused resources more.
-- Modified the behavior of update_job() in job_mgr.c to return when the first
error is encountered instead of continuing with more job updates.
-- Removed all references to the following slurm.conf parameters, all of which
have been removed or replaced since version 2.0 or earlier: HashBase,
HeartbeatInterval, JobAcctFrequency, JobAcctLogFile (instead use
AccountingStorageLoc), JobAcctType, KillTree, MaxMemPerTask, and
MpichGmDirectSupport.
-- Fix bug in slurmctld restart logic that improperly reported jobs had
invalid features: "Job 65537 has invalid feature list: fat".
Danny Auble
committed
-- BLUEGENE - Removed thread pool for destroying blocks. It turns out the
memory leak we were concerned about for creating and destroying threads
in a plugin doesn't exist anymore. This increases throughput dramatically,
allowing multiple jobs to start at the same time.
Danny Auble
committed
-- BLUEGENE - Removed thread pool for starting and stopping jobs. For similar
reasons as noted above.
-- BLUEGENE - Handle blocks that never deallocate.
* Changes in SLURM 2.2.0.pre9
=============================
Danny Auble
committed
-- sbatch can now submit jobs to multiple clusters and run on the earliest
available.
-- Fix bug introduced in pre8 that prevented job dependencies and job
triggers from working without the --enable-debug configure option.
-- Replaced slurm_addr with slurm_addr_t
-- Skeleton code added for BlueGeneQ.
-- Jobs can now be submitted to multiple partitions (job queues) and use the
one permitting earliest start time.
Danny Auble
committed
-- Change slurmdb_coord_table back to acct_coord_table to keep consistant
with < 2.1.
-- Introduced locking system similar to that in the slurmctld for the
assoc_mgr.
-- Added ability to change a users name in accounting.
-- Restore squeue support for "%G" format (group id) accidentally removed in
2.2.0.pre7.
-- Added preempt_mode option to QOS.
-- Added a grouping=individual for sreport size reports.
-- Added remove_qos logic to jobs running under a QOS that was removed.
-- scancel now exits with a 1 if any job is non-existant when canceling.
-- Better handling of select plugins that don't exist on various systems for
cross cluster communication. Slurmctld, slurmd, and slurmstepd now only
load the default select plugin as well.
-- Better error handling when loading plugins.
-- Prevent scontrol from aborting if getlogin() returns NULL.
-- Prevent scontrol segfault when there are hidden nodes.
-- Prevent srun segfault after task launch failure.
-- Added job_submit/lua plugin.
-- Fixed sinfo on a bluegene system to print correctly the output for:
Danny Auble
committed
sinfo -e -o "%9P %6m %.4c %.22F %f"
-- Add scontrol commands "hold" and "release" to simplify setting a job's
priority to 0 or 1. Also tests that the job is in pending state.
-- Increase maximum node list size (for incoming RPC) from 1024 bytes to 64k.
-- In the backup slurmctld, purge triggers before recovering trigger state to
avoid duplicate entries.
-- Fix bug in sacct processing of --fields= option.
-- Fix bug in checkpoint/blcr for jobs spanning multiple nodes introduced when
changing some variable names in version 2.2.0.pre5.
-- Removed the vestigal set_max_cluster_usage() function from the Priority
Plugin API.
-- Modify the output of "scontrol show job" for the field ReqS:C:T=. Fields
not specified by the user will be reported as "*" instead of 65534.
-- Added DefaultQOS option for an association.
Danny Auble
committed
-- BLUEGENE - Added -B option to the slurmctld to clear created blocks from
the system on start.
-- BLUEGENE - Added option to scontrol & sview to recreate existing blocks.
Danny Auble
committed
-- Fixed flags for returning messages to use the correct munge key when going
cross-cluster.
Danny Auble
committed
-- BLUEGENE - Added option to scontrol & sview to resume blocks in an error
state instead of just freeing them.
Danny Auble
committed
-- sview patched to allow multiple row selection of jobs, patch from Dan Rusak
-- Lower default slurmctld server thread count from 1024 to 256. Some systems
process threads on a last-in first-out basis and the high thread count was
causing unexpectedly high delays for some RPCs.
-- Added to sacctmgr the ability for admins to reset the raw usage of a user
or account
-- Improved the efficiency of a few lines in sacctmgr
* Changes in SLURM 2.2.0.pre8
=============================
-- Add DebugFlags parameter of "Backfill" for sched/backfill detailed logging.
-- Add DebugFlags parameter of "Gang" for detailed logging of gang scheduling
activities.
-- Add DebugFlags parameter of "Priority" for detailed logging of priority
multifactor activities.
-- Add DebugFlags parameter of "Reservation" for detailed logging of advanced
reservations.
-- Add run time to mail message upon job termination and queue time for mail
message upon job begin.
-- Add email notification option for job requeue.
-- Generate a fatal error if the srun --relative option is used when not
within an existing job allocation.
-- Modify the meaning of InactiveLimit slightly. It will now cancel the job
allocation created using the salloc or srun command if those commands
cease responding for the InactiveLimit regardless of any running job steps.
This parameter will no longer effect jobs spawned using sbatch.
-- Remove AccountingStoragePass and JobCompPass from configuration RPC and
scontrol show config command output. The use of SlurmDBD is still strongly
recommended as SLURM will have limited database functionality or protection
otherwise.
-- Add sbatch options of --export and SBATCH_EXPORT to control which
environment variables (if any) get propagated to the spawned job. This is
particularly important for jobs that are submitted on one cluster and run
on a different cluster.
-- Fix bug in select/linear when used with gang scheduling and there are
preempted jobs at the time slurmctld restarts that can result in over-
subscribing resources.
-- Added keeping track of the qos a job is running with in accounting.
Danny Auble
committed
-- Fix for handling correctly jobs that resize, and also reporting correct
stats on a job after it finishes.
Danny Auble
committed
-- Modify gang scheduler so with SelectTypeParameter=CR_CPUS and task
affinity is enabled, keep track of the individual CPUs allocated to jobs
rather than just the count of CPUs allocated (which could overcommit
specific CPUs for running jobs).
-- Modify select/linear plugin data structures to eliminate underflow errors
for the exclusive_cnt and tot_job_cnt variables (previously happened when
slurmctld reconfigured while the job was in completing state).
-- Change slurmd's working directory (and location of core files) to match
that of the slurmctld daemon: the same directory used for log files,
SlurmdLogFile (if specified with an absolute pathname) otherwise the
directory used to save state, SlurmdSpoolDir.
-- Add sattach support for the --pty option.
-- Modify slurmctld communications logic to accept incoming messages on more
than one port for improved scalability.
-- Add SchedulerParameters option of "defer" to avoid trying to schedule a
job at submission time, but to attempt scheduling many jobs at once for
improved performance under heavy load.
-- Correct logic controlling slurmctld thread limit eliminating check of
RLIMIT_STACK.
-- Make slurmctld's trigger logic more robust in the event that job records
get purged before their trigger can be processed (e.g. MinJobAge=1).
-- Add support for users to hold/release their own jobs (submit the job with
srun/sbatch --hold/-H option or use "scontrol update jobid=# priority=0"
to hold and "scontrol update jobid=# priority=1" to release).
-- Added ability for sacct to query jobs by qos and a range of timelimits.
-- Added ability for sstat to query pids of steps running.
-- Support time specification in UTS format with a prefix of "uts" (e.g.
"sbatch --begin=uts458389988 my.script").
* Changes in SLURM 2.2.0.pre7
=============================
-- Fixed issue with sacctmgr if querying against non-existent cluster it
Danny Auble
committed
works the same way as 2.1.
-- Added infrastructure to support allocation of generic node resources (gres).
-Modified select/linear and select/cons_res plugins to allocate resources
at the level of a job without oversubcription.
-Get sched/backfill operating with gres allocations.
-Get gres configuration changes (reconfiguration) working.
-Have job steps allocate resources.
-Modified job step credential to include the job's and step's gres
allocation details.
-Integrate with HWLOC library to identify GPUs and NICs configured on each
node.
-- SLURM commands (squeue, sinfo, etc...) can now go cross-cluster on like
linux systems. Cross-cluster for bluegene to linux and such should
-- Added the ability to configure PreemptMode on a per-partition basis.
-- Change slurmctld's default thread limit count to 1024, but adjust that down
as needed based upon the process's resource limits.
-- Removed the non-functional "SystemCPU" and "TotalCPU" reporting fields from
sstat and updated man page
-- Correct location of apbasil command on Cray XT systems.
-- Fixed bug in MinCPU and AveCPU calculations in sstat command
-- Send message to srun when the Prolog takes too long (MessageTimeout) to
complete.
-- Change timeout for socket connect() to be half of configured MessageTimeout.
-- Added high-throughput computing web page with configuration guidance.
-- Use more srun sockets to process incoming PMI (MPICH2) connections for
better scalability.
-- Added DebugFlags for the select/bluegene plugin: DEBUG_FLAG_BG_PICK,
DEBUG_FLAG_BG_WIRES, DEBUG_FLAG_BG_ALGO, and DEBUG_FLAG_BG_ALGO_DEEP.
-- Remove vestigial job record field "kill_on_step_done" (internal to the
slurmctld daemon only).
-- For MPICH2 jobs: Clear PMI state between job steps.
* Changes in SLURM 2.2.0.pre6
=============================
-- sview - added ability to see database configuration.
-- sview - added ability to add/remove visible tabs.
-- sview - change way grid highlighting takes place on selected objects.
-- Added infrastructure to support allocation of generic node resources.
-Added node configuration parameter of Gres=.
-Added ability to view/modify a node's gres using scontrol, sinfo and sview.
-Added salloc, sbatch and srun --gres option.
-Added ability to view a job or job step's gres using scontrol, squeue and
sview.
-Added new configuration parameter GresPlugins to define plugins used to
manage generic resources.
-Added DebugFlags option of "gres" for detailed debugging of gres actions.
-- Slurmd modified to log slow slurmstepd startup and note possible file system
problem.
-- sview - There is now a .slurm/sviewrc created when running sview.
Danny Auble
committed
Defaults are put in there as to how sview looks when first launched.
You can set these by Ctrl-S or Options->Set Default Settings.
-- Add scontrol "wait_job <job_id>" option to wait for nodes to boot as needed.
Moe Jette
committed
Useful for batch jobs (in Prolog, PrologSlurmctld or the script) if powering
down idle nodes.
-- Added salloc and sbatch option --wait-for-nodes. If set non-zero, job
initiation will be delayed until all allocated nodes have booted. Salloc
will log the delay with the messages "Waiting for nodes to boot" and "Nodes
are ready for use".
Danny Auble
committed
-- The Priority/mulitfactor plugin now takes into consideration size of job
in cpus as well as size in nodes when looking at the job size factor.
Previously only nodes were considered.
Danny Auble
committed
-- When using the SlurmDBD messages waiting to be sent will be combined
and sent in one message.
-- Remove srun's --core option. Move the logic to an optional SPANK plugin
(currently in the contribs directory, but plan to distribute through
http://code.google.com/p/slurm-spank-plugins/).
Danny Auble
committed
-- Patch for adding CR_CORE_DEFAULT_DIST_BLOCK as a select option to layout
jobs using block layout across cores within each node instead of cyclic
which was previously the default.
Danny Auble
committed
-- Accounting - When removing associations if jobs are running, those jobs
must be killed before proceeding. Before the jobs were killed
automatically thus causing user confusion on what is most likely an
admin's mistake.
-- sview - color column keeps reference color when highlighting.
-- Configuration parameter MaxJobCount changed from 16-bit to 32-bit field.
The default MaxJobCount was changed from 5,000 to 10,000.
Danny Auble
committed
-- SLURM commands (squeue, sinfo, etc...) can now go cross-cluster on like
linux systems. Cross-cluster for bluegene to linux and such does not
currently work. You can submit jobs with sbatch. Salloc and srun are not
cross-cluster compatible, and given their nature to talk to actual compute
Danny Auble
committed
nodes these will likely never be.
-- salloc modified to forward SIGTERM to the spawned program.
-- In sched/wiki2 (for Moab support) - Add GRES and WCKEY fields to MODIFYJOBS
and GETJOBS commands. Add GRES field to GETNODES command.
-- In struct job_descriptor and struct job_info: rename min_sockets to
sockets_per_node, min_cores to cores_per_socket, and min_threads to
threads_per_core (the values are not minimum, but represent the target
values).
-- Fixed bug in clearing a partition's DisableRootJobs value reported by
Hongjia Cao.
-- Purge (or ignore) terminated jobs in a more timely fashion based upon the
MinJobAge configuration parameter. Small values for MinJobAge should improve
responsiveness for high job throughput.
* Changes in SLURM 2.2.0.pre5
=============================
-- Modify commands to accept time format with one or two digit hour value
-- Modify time parsing logic to accept "minute", "hour", "day", and "week" in
addition to the currently accepted "minutes", "hours", etc.
-- Add slurmd option of "-C" to print actual hardware configuration and exit.
-- Pass EnforcePartLimits configuration parameter from slurmctld for user
commands to see the correct value instead of always "NO".
-- Modify partition data structures to replace the default_part,
disable_root_jobs, hidden and root_only fields with a single field called
"flags" populated with the flags PART_FLAG_DEFAULT, PART_FLAG_NO_ROOT
PART_FLAG_HIDDEN and/or PART_FLAG_ROOT_ONLY. This is a more flexible
solution besides making for smaller data structures.
-- Add node state flag of JOB_RESIZING. This will only exist when a job's
accounting record is being written immediately before or after it changes
size. This permits job accounting records to be written for a job at each
size.
-- Make calls to jobcomp and accounting_storage plugins before and after a job
changes size (with the job state being JOB_RESIZING). All plugins write a
record for the job at each size with intermediate job states being
-- When changing a job size using scontrol, generate a script that can be
executed by the user to reset SLURM environment variables.
-- Modify select/linear and select/cons_res to use resources released by job
resizing.
-- Added to contribs foundation for Perl extension for slurmdb library.
-- Add new configuration parameter JobSubmitPlugins which provides a mechanism
to set default job parameters or perform other site-configurable actions at
job submit time.
-- Better postgres support for accounting, still beta.
-- Speed up job start when using the slurmdbd.

-- Forward step failure reason back to slurmd before in some cases it would
just be SLURM_FAILURE returned.
-- Changed squeue to fail when passed invalid -o <output_format> or
-S <sort_list> specifications.
* Changes in SLURM 2.2.0.pre4
=============================
-- Add support for a PropagatePrioProcess configuration parameter value of 2
to restrict spawned task nice values to that of the slurmd daemon plus 1.
This insures that the slurmd daemon always have a higher scheduling
priority than spawned tasks.
-- Add support in slurmctld, slurmd and slurmdbd for option of "-n <value>" to
-- Fixed slurm_load_slurmd_status and slurm_pid2jobid to work correctly when
multiple slurmds are in use.
Danny Auble
committed
-- Altered srun to set max_nodes to min_nodes if not set when doing an
allocation to mimic that which salloc and sbatch do. If running a step if
the max isn't set it remains unset.
-- Applied patch from David Egolf (David.Egolf@Bull.com). Added the ability
to purge/archive accounting data on a day or hour basis, previously
it was only available on a monthly basis.
Moe Jette
committed
-- Add support for maximum node count in job step request.
-- Fix bug in CPU count logic for job step allocation (used count of CPUS per
node rather than CPUs allocated to the job).
-- Add new configuration parameters GroupUpdateForce and GroupUpdateTime.
See "man slurm.conf" for details about how these control when slurmctld
updates its information of which users are in the groups allowed to use
partitions.
Danny Auble
committed
-- Added sacctmgr list events which will list events that have happened on
clusters in accounting.
-- Permit a running job to shrink in size using a command of
"scontrol update JobId=# NumNodes=#" or
"scontrol update JobId=# NodeList=<names>". Subsequent job steps must
explicitly specify an appropriate node count to work properly.
-- Added resize_time field to job record noting the time of the latest job
size change (to be used for accounting purposes).
Danny Auble
committed
-- sview/smap now hides hidden partitions and their jobs by default, with an
option to display them.
* Changes in SLURM 2.2.0.pre3
=============================
-- Refine support for TotalView partial attach. Add parameter to configure
program of "--enable-partial-attach".
-- In select/cons_res, the count of CPUs on required nodes was formerly
ignored in enforcing the maximum CPU limit. Also enforce maximum CPU
limit when the topology/tree plugin is configured (previously ignored).
-- In select/cons_res, allocate cores for a job using a best-fit approach.
-- In select/cons_res, for jobs that can run on a single node, use a best-fit
packing approach.
-- Add support for new partition states of DRAIN and INACTIVE and new partition
option of "Alternate" (alternate partition to use for jobs submitted to
partitions that are currently in a state of DRAIN or INACTIVE).
-- Add group membership cache. This can substantially speed up slurmctld
startup or reconfiguration if many partitions have AllowGroups configured.
-- Added slurmdb api for accessing slurm DB information.
-- In select/linear: Modify data structures for better performance and to
avoid underflow error messages when slurmctld restarts while jobs are
in completing state.
-- Added hash for slurm.conf so when nodes check in to the controller it can
verify the slurm.conf is the same as the one it is running. If not an
error message is displayed. To silence this message add NO_CONF_HASH
to DebugFlags in your slurm.conf.
-- Added error code ESLURM_CIRCULAR_DEPENDENCY and prevent circular job
dependencies (e.g. job 12 dependent upon job 11 AND job 11 is dependent
upon job 12).
-- Add BootTime and SlurmdStartTime to available node information.
-- Fixed moab_2_slurmdb to work correctly under new database schema.
-- Slurmd will drain a compute node when the SlurmdSpoolDir is full.
* Changes in SLURM 2.2.0.pre2
=============================
-- Add support for spank_get_item() to get S_STEP_ALLOC_CORES and
S_STEP_ALLOC_MEM. Support will remain for S_JOB_ALLOC_CORES and
S_JOB_ALLOC_MEM.
-- Kill individual job steps that exceed their memory limit rather than
killing an entire job if one step exceeds its memory limit.
-- Added configuration parameter VSizeFactor to enforce virtual memory limits
for jobs and job steps as a percentage of their real memory allocation.
-- Add scontrol ability to update job step's time limits.
-- Add scontrol ability to update job's NumCPUs count.
-- Add --time-min options to salloc, sbatch and srun. The scontrol command
has been modified to display and modify the new field. sched/backfill
plugin has been changed to alter time limits of jobs with the
--time-min option if doing so permits earlier job initiation.
-- Add support for TotalView symbol MPIR_partial_attach_ok with srun support
to release processes which TotalView does not attach to.
-- Add new option for SelectTypeParameters of CR_ONE_TASK_PER_CORE. This
option will allocate one task per core by default. Without this option,
by default one task will be allocated per thread on nodes with more than
one ThreadsPerCore configured.
-- Avoid accounting separately for a current pid corresponds to a Light Weight
Process (Thread POSIX) appearing in the /proc directory. Only account for
the original process (pid==tgid) to avoid accounting for memory use more
than once.
-- Add proctrack/cgroup plugin which uses Linux control groups (aka cgroup)
to track processes on Linux systems having this feature enabled (kernel
>= 2.6.24).
-- Add logging of license transations including job_id.
-- Add configuration parameters SlurmSchedLogFile and SlurmSchedLogLevel to
support writing scheduling events to a separate log file.
-- Added contribs/web_apps/chart_stats.cgi, a web app that invokes sreport to
retrieve from the accounting storage db a user's request for job usage or
machine utilization statistics and charts the results to a browser.
Danny Auble
committed
-- Massive change to the schema in the storage_accounting/mysql plugin. When
starting the slurmdbd the process of conversion may take a few minutes.
You might also see some errors such as 'error: mysql_query failed: 1206
The total number of locks exceeds the lock table size'. If you get this,
do not worry, it is because your setting of innodb_buffer_pool_size in
your my.cnf file is not set or set too low. A decent value there should
be 64M or higher depending on the system you are running on. See
RELEASE_NOTES for more information. But setting this and then
restarting the mysqld and slurmdbd will put things right. After this
change we have noticed 50-75% increase in performance with sreport and
sacct.
Danny Auble
committed
-- Fix for MaxCPUs to honor partitions of 1 node that have more than the
maxcpus for a job.
-- Add support for "scontrol notify <message>" to work for batch jobs.
-- Added SLURM_VERSION_NUMBER and removed SLURM_API_VERSION from
slurm/slurm.h.
Danny Auble
committed
-- Added support to handle communication with SLURM 2.1 clusters. Job's
should not be lost in the future when upgrading to higher versions of
SLURM.
-- Added withdeleted options for listing clusters, users, and accounts
-- Remove PLPA task affinity functions due to that package being deprecated.
-- Preserve current partition state information and node Feature and Weight
information rather than use contents of slurm.conf file after slurmctld
restart with -R option or SIGHUP. Replace information with contents of
slurm.conf after slurmctld restart without -R or "scontrol reconfigure".
See RELEASE_NOTES file fore more details.
-- Modify SLURM's PMI library (for MPICH2) to properly execute an executable
program stand-alone (single MPI task launched without srun).
-- Made GrpCPUs and MaxCPUs limits work for select/cons_res.
Danny Auble
committed
-- Moved all SQL dependant plugins into a seperate rpm slurm-sql. This
should be needed only where a connection to a database is needed (i.e.
where the slurmdbd is running)
-- Add command line option "no_sys_info" to PAM module to supress system
logging of "access granted for user ...", access denied and other errors
will still be logged.
Danny Auble
committed
-- sinfo -R now has the user and timestamp in separate fields from the reason.
-- Much functionality has been added to account_storage/pgsql. The plugin
is still in a very beta state. It is still highly advised to use the
mysql plugin, but if you feel like living on the edge or just really
like postgres over mysql for some reason here you go. (Work done
primarily by Hongjia Cao, NUDT.)
* Changes in SLURM 2.1.17
=========================
* Changes in SLURM 2.1.16
=========================
-- Fixed minor warnings from gcc-4.5
-- Fixed initialization of accounting_stroage_enforce in the slurmctld.
-- Fixed bug where if GrpNodes was lowered while pending jobs existed and where
above the limit the slurmctld would seg fault.
-- Fixed minor memory leak when unpack error happens on an
association_shares_object_t.
-- Set Lft and Rgt correctly when adding association. Fix for regression
caused in 2.1.15, cosmetic fix only.
-- Replaced optarg which was undefined in some spots to make sure ENV vars are
set up correctly.
-- When removing an account from a cluster with sacctmgr you no longer get
a list of previously deleted associations.
-- Fix to make jobcomp/(pg/my)sql correctly work when the database name is
different than the default.
* Changes in SLURM 2.1.15
=========================
-- Fix bug in which backup slurmctld can purge job scripts (and kill batch
jobs) when it assumes primary control, particularly when this happens
multiple times in a short time interval.
-- In sched/wiki and sched/wiki2 add IWD (Initial Working Directory) to the
information reported about jobs.
-- Fix bug in calculating a daily or weekly reservation start time when the
reservation is updated. Patch from Per Lundqvist (National Supercomputer
Centre, Linköping University, Sweden).
-- Fix bug in how job step memory limits are calculated when the --relative
option is used.
-- Restore operation of srun -X option to forward SIGINT to spawned tasks
without killing them.
-- Fixed a bug in calculating the root account's raw usage reported by Par
Andersson
-- Fixed a bug in sshare displaying account hierarchy reported by Per
Lundqvist.
-- In select/linear plugin, when a node allocated to a running job is removed
from a partition, only log the event once. Fixes problem reported by Per
Lundqvist.
* Changes in SLURM 2.1.14
=========================
-- Fixed coding mistakes in _slurm_rpc_resv_show() and job_alloc_info() found
while reviewing the code.
-- Fix select/cons_res logic to prevent allocating resources while jobs
previously allocated resources on the node are still completing.
-- Fixed typo in job_mgr.c dealing with qos instead of associations.
-- Make sure associations and qos' are initiated when added.
-- Fixed wrong initialization for wckeys in the association manager.
-- Added wiki.conf configuration parameter of HidePartitionNodes. See
"man wiki.conf" for more information.
-- Add "JobAggregationTime=#" field SchedulerParameter configuration parameter
output.
-- Modify init.d/slurm and slurmdbd scripts to prevent the possible
inadvertent inclusion of "." in LD_LIBRARY_PATH environment variable.
To fail, the script would need to be executed by user root or SlurmUser
without the LD_LIBRARY_PATH environment variable set and there would
have to be a maliciously altered library in the working directory.
Thanks to Raphael Geissert for identifying the problem. This addresses
security vulnerability CVE-2010-3380.
* Changes in SLURM 2.1.13

and creating a step, also fix salloc to assume identity at the correct
time as well.
-- BLUEGENE - Fixed issue with jobs being refused when running dynamic mode

-- Removed bad #define _SLURMD_H from slurmd/get_mach_stat.h. Didn't appear
to cause any problems being there, just incorrect syntax.
-- Validate the job ID when salloc or srun receive an SRUN_JOB_COMPLETE RPC to
avoid killing the wrong job if the original command exits and the port gets
re-used by another command right away.
-- Fix to node in correct state in accounting when updating it to drain from
scontrol/sview.
-- BLUEGENE - Removed incorrect unlocking on error cases when starting jobs.

the slurmctld. Previously the slurmctld would have to be restarted.
This problem only exists when setting a users association limit to -1.
-- Patch from Matthieu Hautreux (CEA) dealing with possible overflows that
could come up with the select/cons_res plugin with uint32_t's being treated
as uint16_t's.
-- Correct logic for creating a reservation with a Duration=Infinite (used to
set reservation end time in the past).
-- Correct logic for creating a reservation that properly handles the OVERLAP
and IGNORE_JOBS flags (flags were ignored under some conditions).
-- Fixed a fair-share calculation bug in the priority/multifactor plugin.
-- Make sure a user entry in the database that was previously deleted is
restored clean when added back, i.e. remove admin privileges previously
given.

the limit is reached running jobs will be killed.
-- Fix deadlock issue in the slurmctld when lowering limits in accounting to
lower than that of pending jobs.
-- Fix bug in salloc, sbatch and srun that could under some conditions process
the --threads-per-core, --cores-per-socket and --sockets-per-node options

correctly when linking to the slurm api.
-- You can now update a jobs QOS from scontrol. Previously you could only do
this from sview.
-- BLUEGENE - Fixed bug where if running in non-dynamic mode sometimes the
start time returned for a job when using test-only would not be correct.
* Changes in SLURM 2.1.9
========================
-- In select/linear - Fix logic to prevent over-subscribing memory with shared
nodes (Shared=YES or Shared=FORCE).
-- Fix for handling -N and --ntasks-per-node without specifying -n with
salloc and sbatch.
-- Fix jobacct_gather/linux if not polling on tasks to give tasks time to
start before doing initial gather.

-- Fix bug in select/cons_res that in some cases would prevent a preempting job
from using of resources already allocated to a preemptable running job.
-- Fix for sreport in interactive mode to honor parsable/2 options.
-- Fixed minor bugs in sacct and sstat commands
-- BLUEGENE - Fixed issue if the slurmd becomes unresponsive and you have
blocks in an error state accounting is correct when the slurmd comes
back up.
-- Corrected documentation for -n option in srun/salloc/sbatch
-- BLUEGENE - when running a willrun test along with preemption the bluegene
plugin now does the correct thing.
-- Fix possible memory corruption issue which can cause slurmctld to abort.
-- BLUEGENE - fixed small memory leak when setting up env.
-- Fixed deadlock if using accounting and cluster changes size in the
database. This can happen if you mistakenly have multiple primary
slurmctld's running for a single cluster, which should rarely if ever
happen.

that the job's exit status gets checked for dependent jobs prior to puring
completed job records.
-- Fix bug in sched/backfill that could set an incorrect expected start time
for a job.
-- BLUEGENE - Fix for systems that have midplanes defined in the database
that don't exist.
-- Accounting, fixed bug where if removing an object a rollback wasn't
possible.
-- Fix possible scontrol stack corruption when listing jobs with very a long
job or working directory name (over 511 characters).
-- Insure that SPANK environment variables set by salloc or sbatch get
propagated to the Prolog on all nodes by setting SLURM_SPANK_* environment
variables for srun's use.
-- In sched/wiki2 - Add support for the MODIFYJOB command to alter a job's
comment field
-- When a cluster first registers with the SlurmDBD only send nodes in an
non-usable state. Before all nodes were sent.
-- Alter sacct to be able to query jobs by association id.
-- Edit documentation for scontrol stating ExitCode as something not alterable.
-- Update documentation about ReturnToService and silently rebooting nodes.
-- When combining --ntasks-per-node and --exclusive in an allocation request
the correct thing, giving the allocation the entire node but only
ntasks-per-node, happens.
-- Fix accounting transaction logs when deleting associations to put the
ids instead of the lfts which could change over time.
-- Fix support for salloc, sbatch and srun's --hint option to avoid allocating
a job more sockets per node or more cores per socket than desired. Also
when --hint=compute_bound or --hint=memory_bound then avoid allocating more
than one task per hyperthread (a change in behavior, but almost certainly
a preferable mode of operation).
* Changes in SLURM 2.1.7
========================
-- Modify srun, salloc and sbatch parsing for the --signal option to accept
either a signal name in addition to the previously supported signal
numbers (e.g. "--signal=USR2@200").
-- BLUEGENE - Fixed sinfo --long --Node output for cpus on a single cnode.
-- In sched/wiki2 - Fix another logic bug in support of Moab being able to
identify preemptable jobs.
-- In sched/wiki2 - For BlueGene systems only: Fix bug preventing Moab from
being able to correctly change the node count of pending jobs.
-- In select/cons_res - Fix bug preventing job preemption with a configuration
of Shared=FORCE:1 and PreemptMode=GANG,SUSPEND.
-- In the TaskProlog, add support for an "unset" option to clear environment
variables for the user application. Also add support for embedded white-
space in the environment variables exported to the user application
(everything after the equal sign to the end of the line is included without
alteration).
-- Do not install /etc/init.d/slurm or /etc/init.d/slurmdbd on AIX systems.
-- BLUEGENE - fixed check for small blocks if a node card of a midplane is
in an error state other jobs can still run on the midplane on other
nodecards.
-- BLUEGENE - Check to make sure job killing is in the active job table in
DB2 when killing the job.

==========================
-- In sched/wiki2 - Fix logic in support of Moab being able to identify
preemptable jobs.
-- Applied fixes to a debug4 message in priority_multifactor.c sent in by
Per Lundqvist
-- BLUEGENE - Fixed issue where incorrect nodecards could be picked when
looking at combining small blocks to make a larger small block.
* Changes in SLURM 2.1.6
========================
-- For newly submitted jobs, report expected start time in squeue --start as
"N/A" rather than current time.
-- Correct sched/backfill logic so that it runs in a more timely fashion.
-- Fixed issue if running on accounting cache and priority/multifactor to
initialize the root association when the database comes back up.
