There's a nice command to run on any given node which tells you slurmd's
view of the node:
$ slurmd -C
NodeName=i004 CPUs=16 Boards=1 SocketsPerBoard=2 CoresPerSocket=8
ThreadsPerCore=1 RealMemory=128691
UpTime=36-17:32:44
Here's an example that I use:
NodeName=i[004-030] Sockets=2 CoresPerSocket=8 ThreadsPerCore=1
RealMemory=128000
@Hoot: note that the line in slurm.conf uses a lower value for RealMemory.
This way you'll avoid having nodes going offline after an upgrade because
the new kernel leaves a couple free MBs less than older one (been there,
done that... :( ).
@Diego: Thanks for reminding me of this! I've added this information to
my Wiki page
