Slurm versions 14.03.9 and 14.11.0-rc2 are now available.
Version 14.03.9 includes quite a few relatively minor bug fixes.
Version 14.11.0-rc2 includes a few bug fixes discovered in recent testing.
Thanks to everyone participating in the testing!
Version 14.11.0 is no longer under active development, but is undergoing
testing for a planned release in early November.
Slurm downloads are available from

* Changes in Slurm 14.03.9
==========================
-- If slurmd fails to stat(2) the configuration print the string describing
the error code.
-- Fix for mixing core base reservations with whole node based reservations
to avoid overlapping erroneously.
-- BLUEGENE - Remove references to Base Partition.
-- sview - If compiled on a non-bluegene system then used to view a BGQ fix
to allow sview to display blocks correctly.
-- Fix bug in update reservation. When modifying the reservation the end time
was set incorrectly.
-- The start time of a reservation that is in ACTIVE state cannot be
modified.
-- Update the cgroup documentation about release agent for devices.
-- MYSQL - fix for setting up preempt list on a QOS for multiple QOS.
-- Correct a minor error in the scancel.1 man page related to the
--signal option.
-- Enhance the scancel.1 man page to document the sequence of signals sent
-- Fix slurmstepd core dump if the cgroup hierarchy is not completed
when terminating the job.
-- Fix hostlist_shift to be able to give correct node names on names with a
different number of dimensions than the cluster.
-- BLUEGENE - Fix invalid pointer in corner case in the plugin.
-- Make sure on a reconfigure the select information for a node is preserved.
-- Correct logic to support job GRES specification over 31 bits (problem
in logic converting int to uint32_t).
-- Remove logic that was creating GRES bitmap for node when not needed (only
needed when GRES mapped to specific files).
-- BLUEGENE - Fix sinfo -tr before it would only print idle nodes correctly.
-- BLUEGENE - Fix for licenses_only reservation on bluegene systems.
-- sview - Verify pointer before using strchr.
-- -M option on tools talking to a Cray from a non-Cray fixed.
-- CRAY - Fix rpmbuild issue for missing file slurm.conf.template.
-- Fix race condition when dealing with removing many associations at
different times when reservations are using the associations that are
being deleted.
-- When a node's state is set to power_down/power_up, then execute
SuspendProgram/ResumeProgram even if previously executed for that node.
-- Fix logic determining when job configuration (i.e. running node power up
logic) is complete.
-- Setting the state of a node in powered down state node to "resume" will
no longer cause it to reboot, but only clear the "drain" state flag.
-- Fix srun documentation to remove SLURM_NODELIST being equivalent as the -w
option (since it isn't).
-- Fix issue with --hint=nomultithread and allocations with steps running
arbitrary layouts (test1.59).
-- PrivateData=reservation modified to permit users to view the reservations
which they have access to (rather then preventing them from seeing ANY
reservation). Backport from 14.11 commit 77c2bd25c.
-- Fix PrivateData=reservation when using associations to give privileges to
a reservation.
-- Better checking to see if select plugin is linear or not.
-- Add support for time specification of "fika" (3 PM).
-- Standardize qstat wrapper more.
-- Provide better estimate of minimum node count for pending jobs using more
job parameters.
-- ALPS - Add SubAllocate to cray.conf file for those who like the way <=2.5
did the ALPS reservation.
-- Safer check to avoid invalid reads when shutting down the slurmctld with
lots of jobs.
-- Fix minor memory leak in the backfill scheduler when shutting down.
-- Add ArchiveResvs to the output of sacctmgr show config and init
the variable
on slurmdbd startup.
-- SLURMDBD - Only set the archive flag if purging the object
(i.e ArchiveJobs PurgeJobs). This is only a cosmetic change.
-- Fix for job step memory allocation logic if step requests GRES and memory
is not allocations are not managed.
-- Fix sinfo to display mixed nodes as allocated in '%F' output.
-- Sview - Fix cpu and node counts for partitions.
-- Ignore NO_VAL in SLURMDB_PURGE_* macros.
-- ALPS - Don't drain nodes if epilog fails. It leaves them in drain state
with no way to get them out.
-- Fix issue with task/affinity oversubscribing cpus erroneously when
using --ntasks-per-node.
-- MYSQL - Fix load of archive files.
-- Treat Cray MPI job calling exit() without mpi_fini() as fatal error for
that specific task and let srun handle all timeout logic.
-- Fix small memory leak in jobcomp/mysql.
-- Correct tracking of licenses for suspended jobs on slurmctld
reconfigure or
restart.
-- If failed to launch a batch job, requeue it in held state.
* Changes in Slurm 14.11.0rc2
=============================
-- Logs for jobs which are explicitly requeued will say so rather than saying
that a node in their allocation failed.
-- Updated the documentation about the remote licenses served by
the Slurm database.
-- Insure that slurm_spank_exit() is only called once from srun.
-- Change the signature of net_set_low_water() to use 4 bytes instead of 8.
-- Export working_cluster_rec in libslurmdb.so as well as move some function
definitions needed for drmaa.
-- If using cons_res or serial cause a fatal in the plugin instead of causing
the SelectTypeParameters to magically set to CR_CPU.
-- Enhance task/affinity auto binding to consider tasks * cpus-per-task.
-- Fix regression the priority/multifactor which would cause memory
corruption.
Issue is only in rc1.
-- Add PrivateData value of "cloud". If set, powered down nodes in the cloud
will be visible.
-- Sched/backfill - Eliminate clearing start_time of running jobs.
-- Fix various backwards compatibility issues.
-- If failed to launch a batch job, requeue it in hold.
