[slurm-users] How to request ONLY one CPU instead of one socket or one node?

[Merlin Hartley]

Seems like you aren't specifying a --mem option, so the default would be to ask for a whole-node’s worth of RAM thus you would use the whole node for each job.

Hope this is useful!

When I submit my job to the cluster, it always request one node instead of one CPU. I am wondering how I can ONLY request one CPU using “sbatch” command? Below is my batch file. Any comments and help would be highly appreciated.
