Dear Marcus and all peers, Thank you so much for your advice. Lit by your suggestion, after comparing slurm.conf in my cluster to another one which can request one CPU, I noticed that the slurm.conf has not been set properly by manufactory. There were not settings for Socket and CPU (# of socket and # of CPU). Thus, when I submit a job to request one CPU, slurm does not request one CPU because it does not have this information. After updating this configuration file and working with the engineer from the manufacture, I can request one CPU now.
I sincerely appreciate everybody's suggestion and time. Hope that my feedback can help the other colleagues who have similar problems.
