external scheduler control of RoolOnly partition (Chris Holmes, HP).

RM_MESH to avoid multiple definitions for these values (one in slurm/slurm.h

 Suse Linux.

code for current Linux clusters and develop all new logic for Blue Gene).

flag the required state saves. Perform the saves using synchronous I/O
from just one thread. Under heavy loads this results in much faster
responsiveness and lowers slurmctld's memory and CPU overhead considerably.

data structure. This eliminates risks associated with re-reading slurm.conf.

Avoid sending TASKS=0 to Wiki; Maui silently rejects the job (insofar as Maui silently does anything)

gracefully kill all jobs allocated resources on those nodes,
gracefully kill all pending jobs that require those nodes,
leave pending jobs that exclude those nodes but ignore those nodes.
Added "best_effort" argument to node_name2bitmap() function.
Fix potential memory leak when maui scheduler interface resets
the required nodes.

Otherwise signal all steps associated with the job (unless individual job

Use it directly from  backfill plugin (instead of API call).

Convert all accessors to use exclusively pointers; this should fix many of the 64-bit incompatibility problems
