[slurm-users] Node is not allocating all CPUs

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:

Why would the number of trackable resources be different from the number of actual CPUs?

Are the jobs getting assigned memory amounts that would only allow 16 processors to be used when the jobs are running on the node?
