One of our testers discovered a regression in version 2.3.1.  If a job is
pending due to PartitionNodeLimit and the limit is relieved with a
'sacctmgr modify qos name=<qos name> set flags=partitionmaxnodes' new jobs
exceeding the partition limit (but not the QOS limit) are allowed to run.
However, the pending job is never allowed to run.  Attached is a patch to
address this problem.  FYI, this problem doesn't exist in version 2.4.
Patch from Bill Brophy, Bull.

Let a job be submitted even if it exceeds a QOS limit. Job will be left
in a pending state until the QOS limit or job parameters change. Patch by
Phil Eckert, LLNL.

There was also some bad code that would reset the conn_type of a block
to SMALL no matter what type of SMALL it was.

This was due to a bug in select/cons_res with some configuration
optiions and job options, especially if there is more than one
thread per core and the job option includes "--threads-per-core=1".

Add ReconfigFlags configuration option to control actions of
"scontrol reconfig". Patch from Don Albert, Bull.

before the db_index was returned information like start time would be lost.

Add numeric range checks to scontrol update options. Patch from Phil Eckert, LLNL.

to use srun instead of runjob.

for this yet though.

Note this is an old bug. The new code keeps slurmstepd alive and it
keeps trying to send step completion message to slurmctld.

This make the same patch to select/linear as Carles Fenoy's patch to
select/cons_res plugin.

Backfill scheduling - Add SchedulerParameters configuration parameter of
"bf_res" to control the resolution in the backfill scheduler's data about
when jobs begin and end. Default value is 60 seconds (used to be 1 second).

Do not drain the compute or front-end node when trying to start a job
for which the UID is not found

Add configure option of "--without-rpath" which builds SLURM tools without
the rpath option, which will work if Munge and BlueGene libraries are in
the default library search path and make system updates easier.

Add support for job allocations with multiple job constraint counts. For
example: salloc -C "[rack1*2&rack2*4]" ... will allocate the job 2 nodes
from rack1 and 4 nodes from rack2. Support for only a single constraint
name been added to job step support.

Add support for GPU memory allocation on Cray systems using SLURM GRES
(Generic RESource) support. Work by Steve Trofinoff, CSCS.
