No, the user is submitting four jobs, each requesting 1/4 of the memory and 1/4
of the CPUs (i.e. 8 out of 32). But even though there are 32 physical cores,
Slurm only shows 16 as trackable resources:

uld the number of trackable resources be different from the number of
actual CPUs?

Thanks. That shows 32 cores, as expected:
# /cm/shared/apps/slurm/19.05.8/sbin/slurmd -C
NodeName=node020 CPUs=32 Boards=1 SocketsPerBoard=2 CoresPerSocket=16
ThreadsPerCore=1 RealMemory=257600
UpTime=0-22:39:36
But I can&#

16.

We've added a new GPU node to our cluster with 32 cores. It contains 2 16-core
sockets, and hyperthreading is turned off, so the total is 32 cores. But jobs
are only being allowed to use 16 cores.
Here's the relevant line from slurm.conf:
NodeName=node020 CoresPerSocket=16 RealMemory=257600 Thr
