Correction to hostlist parsing bug introduced in v2.6.4 for hostlists with
more than one numeric range in brackets (e.g. rack[0-3]_blade[0-63]").
bug505

Just a start for now

Added -S/--core-spec option to salloc, sbatch and srun commands to reserve
    specialized cores for system use. Modify sview and scontrol to set/get
    core_spec
struct job_info / slurm_job_info_t: Added core_spec
struct job_descriptorjob_desc_msg_t: Added core_spec

The system really can not handle larger job arrays without adding
a job array data structure, but this puts some of the infrastructure
in place now.

to offer a greater priority range based upon utilization.

Add argument to priority plugin's priority_p_reconfig function to note
when the association and QOS used_cpu_run_secs field has been reset.
Without this flag, we remove time on "scontrol setdebug" or
"scontrol setdebugflag" that can result in used_cpu_run_secs
going negative or otherwise get bad values.
Correction to logic added in commit 6d793189

Fix to work with change logic introduced in Slurm version 2.6.3
scheduling logic which prevented Maui/Moab from starting jobs.

Add support for -W block=true	(wait for job completion)
Clear PBS_NODEFILE environment variable

Add support for dependencies of job array elements (e.g.
"sbatch --depend=afterok:123_4 ..."). This does not support
depenendencies of ALL job array elements, only individual job
array elements.

preforms the allocation, regression in 2.6.3.

Previously the SlurmdDebug value in slurm.conf was ignored if the
previous value was not 3/init

Effect is minimal without multiple partitions and larger system sizes.
With 40 partitions and about 600 nodes each, time goes from about
13 secs to 4 secs).

This avoids building hostlist information with NodeHostName and
NodeAddr information unless explisitly requested and can improve
performance for the default mode of operation by about 65%.

Correct sbatch documentation and job_submit/pbs plugin "%j" is job ID,
not "%J" (which is job_id.step_id).

Without this change a job with a reason of WAIT_PART_DOWN,
WAIT_PART_INACTIVE, WAIT_PART_NODE_LIMIT, WAIT_PART_TIME_LIMIT, or
WAIT_QOS_THRES would not be cleared when that reason no longer
applied.

Add cgroup create retry logic in case one step is starting at the
same time as another step is ending and the logic to create
and delete cgroups overlaps.

If a node has GRES and multiple threads per core the select/cons_res
plugin can get stuck in an infinite loop.

Previously a node failure would always requeue the job

Restore default behavior of allocating cores to jobs on a cyclic basis
across the sockets unless SelectTypeParameters=CR_CORE_DEFAULT_DIST_BLOCK
or user specifies other distribution options.
