0















How can I determine the optimum/maximum number of CPUs per task when running a job? Is there a way to display the total available memory on a given CPU as well?

          You can use sinfo to find maximum CPU/memory per node. To quote from here:



          $ sinfo -o "%15N %10c %10m  %25f %10G"

          I'm not sure what you mean by optimum CPU "per task". This depends on the specific program you are attempting to run.
