* Changes in Slurm 18.08.4
==========================
-- burst_buffer/cray - avoid launching a job that would be immediately
cancelled due to a DataWarp failure.
-- Fix message sent to user to display preempted instead of time limit when
a job is preempted.
-- Fix memory leak when a failure happens processing a nodes gres config.
-- Improve error message when failures happen processing a nodes gres config.
-- When building rpms ignore redundant standard rpaths and insecure relative
rpaths, for RHEL based distros which use "check-rpaths" tool.
-- Don't skip jobs in scontrol hold.
-- Avoid locking the job_list when unneeded.
-- Allow --cpu-bind=verbose to be used with SLURM_HINT environment variable.
-- Make it so fixing runaway jobs will not alter the same job requeued
when not runaway.
-- Avoid checking state when searching for runaway jobs.
-- Remove redundant check for end time of job when searching for runaway jobs.
-- Make sure that we properly check for runawayjobs where another job might
have the same id (for example, if a job was requeued) by also checking the
submit time.
-- Add scontrol update job ResetAccrueTime to clear a job's time
previously accrued for priority.
-- cons_res: Delay exiting cr_job_test until after cores/cpus are calculated
and distributed.
-- Fix bug where binary in cwd would trump binary in PATH with test_exec.
-- Fix check to test printf("%s\n", NULL); to not require
-Wno-format-truncation CFLAG.
-- Fix JobAcctGatherParams=UsePss to report the correct usage.
-- Fix minor memory leak in pmix plugin.
-- Fix minor memory leak in slurmctld when reading configuration.
-- Handle return codes correctly from pthread_* functions.
-- Fix minor memory leak when a slurmd is unable to contact a slurmctld
when trying to register.
-- Fix sreport sizesbyaccount report when using Flatview and accounts.
-- Fix incorrect shift when dealing with node weights and scheduling.
-- libslurm/perl - Fix segfault caused by incorrect hv_to_slurm_ctl_conf.
-- Add qos and assoc options to confirmation dialogs.
-- Handle updating identical license or partition information correctly.
-- Makes sure accounts and QOS' are all lower case to match documentation
when read in from the slurm.conf file.
-- Don't consider partitions without enough nodes in reservation,
main scheduler.
-- Set SLURM_NTASKS correctly if having to determine from other options.
-- Removed GCP scripts from contribs. Now located at:
https://github.com/SchedMD/slurm-gcp.
-- Don't check existence of srun --prolog or --epilog executables when set to
"none" and SLURM_TEST_EXEC is used.
-- Add "P" suffix support to job and step tres specifications.
-- When doing a reconfigure handle QOS' GrpJobsAccrue correctly.
-- Remove unneeded extra parentheses from sh5util.
-- Fix jobacct_gather/cgroup to work correctly when more than one task is
started on a node.
-- If requesting --ntasks-per-node with no tasks set tasks correctly.
-- Accept modifiers for TRES originally added in 6f0342e0358.
-- Don't remove reservation on slurmctld restart if nodes are removed from
configuration.
-- Fix bad xfree in task/cgroup.
-- Fix removing counters if a job array isn't subject to limits and is
canceled while pending.
-- Make sure SLURM_NTASKS_PER_NODE is set correctly when env is overwritten
by the command line.
-- Clean up step on a failed node correctly.
-- mpi/pmix: Fixed the logging of collective state.
-- mpi/pmix: Make multi-slurmd work correctly when using ring communication.
-- mpi/pmix: Fix double invocation of the PMIx lib fence callback.
-- mpi/pmix: Remove unneeded libpmix callback drop in tree-based coll.
-- Fix race condition in route/topology when the slurmctld is reconfigured.
-- In route/topology validate the slurmctld doesn't try to initialize the
node system.
-- Fix issue when requesting invalid gres.
-- Validate job_ptr in backfill before restoring preempt state.
-- Fix issue when job's environment is minimal and only contains variables
Slurm is going to replace internally.
-- When handling runaway jobs remove all usage before rollup to remove any
time that wasn't existent instead of just updating lines that have time
with a lesser time.
-- salloc - set SLURM_NTASKS_PER_CORE and SLURM_NTASKS_PER_SOCKET in the
environment if the corresponding command line options are used.
-- slurmd - fix handling of the -f flag to specify alternate config file
locations.
-- Fix scheduling logic to avoid using nodes that require a reboot for KNL
node change when possible.
-- Fix scheduling logic bug. There should have been a test for _not_
NODE_SET_REBOOT to continue.
-- Fix a scheuling logic bug with respect to XOR operation support when there
are down nodes.
-- If there is a constraint construct of the form "[...&...]"
then an error is generated if more than one of those specifications
contains KNL NUMA or MCDRAM modes.
-- Fix stepd segfault race if slurmctld hasn't registered with the launching
slurmd yet delivering it's TRES list.
-- Add SchedulerParameters option of bf_ignore_newly_avail_nodes to avoid
scheduling lower priority jobs on resources that become available during
the backfill scheduling cycle when bf_continue is enabled.
-- Decrement message_connections in stepd code on error path correctly.
-- Decrease an error message to be debug.
-- Fix missing suffixes in squeue.

can be located on the node.

-- job_submit/lua: Add several slurmctld return codes.
-- job_submit/lua: Add user/group info to jobs.
-- Fix formatting issues when printing uint64_t.
-- Bump RLIMIT_NOFILE for daemons in systemd services.
-- Expand %x in job name in 'scontrol show job'.
-- salloc/sbatch/srun - print warning if mutually exclusive options of --mem
and --mem-per-cpu are both set.
