Slurm 14.11.0 is now available


Slurm version 14.11.0 is now available. This is a major Slurm release 
with many new features. See the RELEASE_NOTES and NEWS files in the 
distribution for detailed descriptions of the changes, a few of which 
are noted below.

Upgrading from Slurm versions 2.6 or 14.03 should proceed without loss 
of jobs or other state.  Just be sure to upgrade the slurmdbd first. 
(Upgrades from pre-releases of version 14.11 may result job loss.)

Slurm downloads are available from http://www.schedmd.com/#repos.

Thanks to all those who helped make this release!

Highlights of changes in Slurm version 14.11.0 include:
  -- Added job array data structure and removed 64k array size restriction.
  -- Added support for reserving CPUs and/or memory on a compute node 
for system
     use.
  -- Added support for allocation of generic resources by model type for
     heterogeneous systems (e.g. request a Kepler GPU, a Tesla GPU, or a 
GPU of
     any type).
  -- Added support for non-consumable generic resources that are 
limited, but
     can be shared between jobs.
  -- Added support for automatic job requeue policy based on exit value.
  -- Refactor job_submit/lua interface. LUA FUNCTIONS NEED TO CHANGE! The
     lua script no longer needs to explicitly load meta-tables, but 
information

Slurm versions 14.03.10 and 14.11.0-rc3 are now available


Slurm version 14.03.10 includes quite a few relatively minor bug fixes, 
and will most likely be the last 14.03 release.  Thanks to all those who 
helped make this a very stable release.

We hope to officially tag 14.11.0 before SC14.  Version 14.11.0-rc3 
includes a few bug fixes discovered in recent testing but is looking 
very stable. Thanks to everyone participating in the testing!  If you 
can, please test this release so we can attempt to fix as many issues as 
we can before we tag 14.11.0.

Just a heads up, version 15.08 is already starting development we will 
most likely tag a pre1 of this later this month.

Slurm downloads are available from http://www.schedmd.com/#repos.

Here are some snips from the NEWS file on what has changed since the 
last releases.

* Changes in Slurm 14.03.10
===========================
  -- Fix a few sacctmgr error messages.
  -- Treat non-zero SlurmSchedLogLevel without SlurmSchedLogFile as a fatal
     error.
