[slurm-users] QOS MaxTRESPU node=X intepretation

[David Magda via slurm-users]

Hello,

Have a question on how to interpret a Node=X MaxTRESPU value for a QOS:

If (e.g.) X=4, and each node has (say) 64 CPUs or cores: if a particular job needs 32 cores, then would two jobs count as the equivalent of one node (2*32=64)? And if X=4 for the QOS, would that mean that eight of these jobs would be able to run ((4*64)/32=8)?

Or does this TRES limit only get activated -N/--nodes is used?

Don't see anything obvious:

Thanks for any info.

Regards,
David
