We are pleased to announce the availability of Slurm version 15.08.6.
This release is primarily in response to the regression in 15.08.5 with
respects to finding the lua library. It also contains a few other minor
bug fixes you may find interesting. Slurm downloads are available from:
http://www.schedmd.com/#repos
We hope everyone has a great holiday and thanks for a great year!
* Changes in Slurm 15.08.6
==========================
-- In slurmctld log file, log duplicate job ID found by slurmd.
Previously was
being logged as prolog/epilog failure.
-- If a job is requeued while in the process of being launch, remove it's
job ID from slurmd's record of active jobs in order to avoid
generating a
duplicate job ID error when launched for the second time (which would
drain the node).
-- Cleanup messages when handling job script and environment variables in
older directory structure formats.
-- Prevent triggering gang scheduling within a partition if configured
with
PreemptType=partition_prio and PreemptMode=suspend,gang.
-- Decrease parallelism in job cancel request to prevent denial of service
when canceling huge numbers of jobs.
-- If all ephemeral ports are in use, try using other port numbers.
-- Revert way lib lua is handled when doing a dlopen, fixing a
regression in
15.08.5.
-- Set the debug level of the rmdir message in xcgroup_delete() to debug2.
-- 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 cosmetic display of AccountingStorageEnforce option "nosteps" when
in use.
-- If a job can never be started due to unsatisfied job dependencies,
report
the full original job dependency specification rather than the
dependencies
remaining to be satisfied (typically NULL).
-- Refactor logic to synchronize active batch jobs and their
script/environment
files, reducing overhead dramatically for large numbers of active jobs.
-- Avoid hard-link/copy of script/environment files for job arrays.
Use the
master job record file for all tasks of the job array.
NOTE: Job arrays submitted to Slurm version 15.08.6 or later will
fail if
the slurmctld daemon is downgraded to an earlier version of Slurm.
-- Move slurmctld mail handler to separate thread for improved
performance.
-- Fix containment of adopted processes from pam_slurm_adopt.
-- If a pending job array has multiple reasons for being in a pending
state,
then print all reasons in a comma separated list.
