HIGHLIGHTS
==========
-- Added TRES (Trackable resources) to track utilization of memory, GRES,
burst buffer, license, and any other configurable resources in the
accounting database.
-- Add configurable billing weight that takes into consideration any TRES when
calculating a job's resource utilization.
-- Add configurable prioritization factor that takes into consideration any
TRES when calculating a job's resource utilization.
-- Add burst buffer support infrastructure. Currently available plugin include
burst_buffer/generic (uses administrator supplied programs to manage file
staging) and burst_buffer/cray (uses Cray APIs to manage buffers).
-- Add power capping support for Cray systems with automatic rebalancing of
power allocation between nodes.
-- 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).
-- Add support for job dependencies joined with OR operator (e.g.
"--depend=afterok:123?afternotok:124").
-- 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).
-- 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.
-- A partition can now have an associated QOS. 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.
-- 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.
-- 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,
the scontrol and sview commands. Added new partition configuration parameter
"ExclusiveUser=yes|no".
-- 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.
-- Optimize resource allocation for systems with dragonfly networks.
-- Added plugin to record job completion information using Elasticsearch.
Libcurl is required for build. Configure slurm.conf as follows
JobCompType=jobcomp/elasticsearch
JobCompLoc=http://YOUR_ELASTICSEARCH_SERVER:9200
-- DATABASE SCHEME HAS CHANGED. WHEN UPDATING THE MIGRATION PROCESS MAY TAKE
SOME AMOUNT OF TIME DEPENDING ON HOW LARGE YOUR DATABASE IS. WHILE UPDATING
NO RECORDS WILL BE LOST, BUT THE SLURMDBD MAY NOT BE RESPONSIVE DURING THE
UPDATE. IT WILL ALSO NOT BE POSSIBLE TO AUTOMATICALLY REVERT THE DATABASE
TO THE FORMAT FOR AN EARLIER VERSION OF SLURM. PLAN ACCORDINGLY.
-- 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. This has introduced an operational issue. See
OTHER CHANGES.
-- MPI/MVAPICH plugin now requires Munge for authentication.
-- 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!
-- Implemented and documented PMIX protocol which is used to bootstrap an
MPI job. PMIX is an alternative to PMI and PMI2.
-- Change default CgroupMountpoint (in cgroup.conf) from "/cgroup" to
"/sys/fs/cgroup" to match current standard.
-- Add Multi-Category Security (MCS) infrastructure to permit nodes to be bound
to specific users or groups.
-- Added --deadline option to salloc, sbatch and srun. Jobs which can not be
completed by the user specified deadline will be terminated with a state of
"Deadline" or "DL".
-- Stop searching sbatch scripts for #PBS directives after 100 lines of
non-comments. Stop parsing #PBS or #SLURM directives after 1024 characters
into a line. Required for decent perforamnce with huge scripts.
RPMBUILD CHANGES
================
-- Remove all *.la files from RPMs.
-- Implemented the --without=package option for configure.
CONFIGURATION FILE CHANGES (see man appropriate man page for details)
=====================================================================
-- Remove DynAllocPort configuration parameter.
-- Added new configuration parameters to support burst buffers:
BurstBufferParameters, and BurstBufferType.
-- 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.
-- 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 the CR_ALLOCATE_FULL_SOCKET configuration option. It is now the
default.
-- Added DebugFlags values of "CpuFrequency", "Power" and "SICP".
-- Added CpuFreqGovernors which lists governors allowed to be set with
--cpu-freq on salloc, sbatch, and srun.
-- 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.
-- 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.
This value also controls how long a requeued job must wait before it can
be started again.
-- Added LaunchParameters configuration parameter.
-- Added new partition configuration parameter "ExclusiveUser=yes|no".
-- Add TopologyParam configuration parameter. Optional value of "dragonfly"
is supported.
-- Added a slurm.conf parameter "PrologEpilogTimeout" to control how long
prolog/epilog can run.
-- Add PrologFlags option of "Contain" to create a proctrack container at
job resource allocation time.
DBD CONFIGURATION FILE CHANGES (see "man slurmdbd.conf" for details)
====================================================================
-- Change default CgroupMountpoint (in cgroup.conf) from "/cgroup" to
"/sys/fs/cgroup" to match current standard.
-- Introduce a new parameter "requeue_setup_env_fail" in SchedulerParameters.
If set, a job that fails to setup the environment will be requeued and the
node drained.
COMMAND CHANGES (see man pages for details)
===========================================
-- Added "--cpu_freq" option to salloc and sbatch.
-- Add sbcast support for file transfer to resources allocated to a job step
rather than a job allocation (e.g. "sbcast -j 123.4 ...").
-- 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).
-- 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.
-- Added BurstBuffer specification to advanced reservation.
-- For advanced reservation, replace flag "License_only" with flag "Any_Nodes".
It can be used to indicate the advanced reservation resources (licenses
and/or burst buffers) can be used with any compute nodes.
-- Add "--sicp" (available for inter-cluster dependencies) and "--power"
(specify power management options) to salloc, sbatch and srun commands.
-- 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.
-- Remove srun --max-launch-time option. The option has not been functional
or documented since Slurm version 2.0.
-- Add "--thread-spec" option to salloc, sbatch and srun commands. This is
the count of threads reserved for system use per node.
-- 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 scontrol options to view and modify layouts tables.
-- Add srun --accel-bind option to control how tasks are bound to GPUs and NIC
Generic RESources (GRES).
-- Add sreport -T/--tres option to identify Trackable RESources (TRES) to
report.
-- sbatch to read OpenLava/LSF/#BSUB options from the batch script.
-- Add sbatch "--wait" option that waits for job completion before exiting.
Exit code will match that of spawned job.
-- Job output and error files can now contain "%" character by specifying
a file name with two consecutive "%" characters. For example,
"sbatch -o "slurm.%%.%j" for job ID 123 will generate an output file named
"slurm.%.123".
-- Increase default sbcast buffer size from 512KB to 8MB.
-- Add "ValidateTimeout" and "OtherTimeout" to "scontrol show burst" output.
-- Implemented the checking configuration functionality using the new -C
options of slurmctld. To check for configuration errors in slurm.conf
run: 'slurmctld -C'.
OTHER CHANGES
=============
-- 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.
-- job_submit/lua: Enable reading and writing job environment variables.
For example: if (job_desc.environment.LANGUAGE == "en_US") then ...
-- The format of HDF5 node-step files has changed, so the sh5util program that
merges them into job files has changed. The command line options to sh5util
have not changed and will continue to service both versions for the next
few releases of Slurm.
-- Add environment variables SLURM_ARRAY_TASK_MAX, SLURM_ARRAY_TASK_MIN,
SLURM_ARRAY_TASK_STEP for job arrays.
-- Add mail wrapper script "smail" that will include job statistics in email
notification messages.
-- Removed support for authd. authd has not been developed and supported since
several years.
-- Enable the hdf5 profiling of the batch step.
-- Eliminate redundant environment and script files for job arrays. This
greatly reduces the number of files involved in managing job arrays.
