[slurm-users] impact of changing SelectTypeParameters?

Might there be any "adverse" impacts to changing
SelectTypeParameters=CR_CPU to SelectTypeParameters=CR_Socket_Memory? Our
compute nodes are, for the most part, exclusive so users are allocated
entire nodes, no sharing, for jobs. We explicitly specify CPUs, Sockets,
CoresPerSocket, & ThreadsPerCore for all our compute nodes.

I assume --nodes, --ntasks, & --cpus-per-task would all work the same, for
example, wouldn't they?

Would something change in the accounting that would make reporting on
numbers of cpu hours or size of jobs change?

Other ramifications?
