[slurm-users] sacct: error

[Eric F. Alemany]

Hi Chris,

Working on weekends - hey ?

when i do "slurmd -C” on one of my execute node, i get:

eric at radonc01:~$ slurmd -C
NodeName=radonc01 slurmd: Considering each NUMA node as a socket
CPUs=32 Boards=1 SocketsPerBoard=4 CoresPerSocket=8 ThreadsPerCore=1 RealMemory=64402
UpTime=2-17:35:12



Also, when i do  “lscpu” i get:

eric at radonc01:~$ lscpu

It seems as the commands give different result (?) - What do you think ?

With Ray suggestion i have a error message for each nodes. Here i am giving
you only one error message from a node.

The interesting thing is if you follow the
Sockets*CoresPerSocket*ThreadsPerCore formula 2x8x2 = 32  however look above
and it says (16) - Strange, no ?

No, Slurm is right.   CPUS != threads.  You've got 16 CPU cores, each with 2
threads.  So in this configuration you can schedule 16 tasks per node and each
task can use 2 threads.

What does "slurmd -C" say on that node?

All the best,
Chris
