 This file describes changes in recent versions of Slurm. It primarily
documents those changes that are of interest to users and administrators.

* 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.
 -- BGQ - Fix issue with job arrays not being handled correctly
    in the runjob_mux plugin.
 -- Print FAIR_TREE, if configured, in "scontrol show config" output for
    PriorityFlags.
 -- Add SLURM_JOB_GPUS environment variable to those available in the Prolog.
 -- Load lua-5.2 library if using lua5.2 for lua job submit plugin.
 -- GRES logic: Prevent bad node_offset due to not preserving no_consume flag.

 -- Fix sprio showing wrong priority for job arrays until priority is
    recalculated.
 -- Account to batch step all CPUs that are allocated to a job not
    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

    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.

    case that "auto binding" doesn't find a match.

 -- Fix perl api tests for libslurmdb to work correctly.
 -- Remove some misleading logs related to non-consumable GRES.
 -- Allow --ignore-pbs to take effect when read as an #SBATCH argument.
 -- Fix Slurmdb::clusters_get() in perl api from not returning information.
 -- Fix TaskPluginParam=Cpusets from logging error message about not being able
    to remove cpuset dir which was already removed by the release_agent.
 -- Fix sorting by time left in squeue.
 -- Fix the file name substitution for job stderr when %A, %a %j and %u
    are specified.

    instead of info.
 -- Enable CUDA v7.0+ use with a Slurm configuration of TaskPlugin=task/cgroup

 -- If a job is requeued because of RequeueExit or RequeueExitHold sent event

 -- 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.
 -- Fix slurmctld initialization problem which could cause requeue of the last
    task in a job array to fail if executed prior to the slurmctld loading
    the maximum size of a job array into a variable in the job_mgr.c module.

* Changes in Slurm 14.11.3
==========================
 -- Prevent vestigial job record when canceling a pending job array record.
 -- Fixed squeue core dump.
 -- Fix job array hash table bug, could result in slurmctld infinite loop or
    invalid memory reference.
 -- In srun honor ntasks_per_node before looking at cpu count when the user
    doesn't request a number of tasks.
 -- Fix ghost job when submitting job after all jobids are exhausted.
 -- MySQL - Enhanced coordinator security checks.
 -- Fix for task/affinity if an admin configures a node for having threads
    but then sets CPUs to only represent the number of cores on the node.
 -- Make it so previous versions of salloc/srun work with newer versions
    of Slurm daemons.
 -- Avoid delay on commit for PMI rank 0 to improve performance with some
    MPI implementations.

 -- Reset node "RESERVED" state as appropriate when deleting a maintenance
    reservation.
 -- Prevent a job manually suspended from being resumed by gang scheduler once
    free resources are available.
 -- Prevent invalid job array task ID value if a task is started using gang
    scheduling.
 -- Fixes for clean build on FreeBSD.
 -- Fix documentation bugs in slurm.conf.5. DenyAccount should be DenyAccounts.
 -- For backward compatibility with older versions of OMPI not compiled
    with --with-pmi restore the SLURM_STEP_RESV_PORTS in the job environment.
 -- Update the html documentation describing the integration with openmpi.

 -- Fix cosmetic info statements when dealing with a job array task instead of
    a normal job.
 -- Fix segfault with job arrays.
 -- Correct the sbatch pbs parser to process -j.

 -- BLUEGENE - Remove check that would erroneously remove the CONFIGURING
    flag from a job while the job is waiting for a block to boot.
 -- Fix segfault in slurmstepd when job exceeded memory limit.
 -- Fix race condition that could start a job that is dependent upon a job array
    before all tasks of that job array complete.

 -- When node gets drained while in state mixed display its status as draining
    in sinfo output.

 -- Fix issue with accounting_storage/filetxt and job arrays not being printed
    correctly.
 -- In proctrack/linuxproc and proctrack/pgid, check the result of strtol()
    for error condition rather than errno, which might have a vestigial error
    code.
 -- Improve information recording for jobs deferred due to advanced
    reservation.
