We are pleased to announce the availability of Slurm versions 18.08.1
and 17.11.10.
This includes an extensive set of fixes made since 18.08.0 was released
at the end of August, and for 17.11.10 since 17.11.9 was released at the
start of August.
Please note that the 17.11.10 release is expected to be the the last
maintenance release of that series (barring any critical security
issues) as our support team has shifted their attention to the 18.08
release. Also note that support for 17.02 ended in August; SchedMD
customers are encourage to upgrade to a supported major release (18.08
or 17.11) at their earliest convenience.
Slurm can be downloaded from https://www.schedmd.com/downloads.php .

been set too low if they're actually set over 2GB.
* Changes in Slurm 17.11.10
===========================
-- Move priority_sort_part_tier from slurmctld to libslurm to make it possible
to run the regression tests 24.* without changing that code since it links
directly to the priority plugin where that function isn't defined.
-- Fix issue where job time limits can increase to max walltime when updating
a job with scontrol.
-- Fix invalid protocol_version manipulation on big endian platforms causing
srun and sattach to fail.
-- Fix for QOS, Reservation and Alias env variables in srun.
-- mpi/pmi2 - Backport 6a702158b49c4 from 18.08 to avoid dangerous detached
thread.
-- When allowing heterogeneous steps make sure we copy all the options to
avoid copying strings that may be overwritten.
-- Print correctly when sh5util finds and empty file.
-- Fix sh5util to not seg fault on exit.
-- Fix sh5util to check correctly for H5free_memory.
-- Adjust OOM monitoring function in task/cgroup to prevent problems in
regression suite from leaked file descriptors.
-- Fix issue with gres when defined with a type and no count
(i.e. gres=gpu/tesla) it would get a count of 0.
-- Allow sstat to talk to slurmd's that are new in protocol version.
-- Permit database names over 33 characters in accounting_storage/mysql.
-- Fix negative values when profiling.
-- Fix srun segfault caused by invalid memory reads on the env.
-- Fix segfault on job arrays when starting controller without dbd up.

for an allocation.

running.
-- Prevent extra resources from being allocated when combining certain flags.

when using --hint=nomultithread.
-- Fix left over socket file when step is ending and using pmi2 with
%n or %h in the spool dir.
-- Fix incorrect spacing for PartitionName lines in 'scontrol write config'.
-- Fix sacct to not print huge reserve times when the job was never eligible.
-- burst_buffer/cray - Add missing locks around assoc_mgr when timing out a
burst buffer.
-- burst_buffer/cray - Update burst buffers when an association or qos
is removed from the system.
