I am running an OpenMPI program on a linux cluster with 4 quad cores per node.
I use qstat -n jobID to check how many processes working in parallel and find that :
But, when I use ssh to be on a node , e..g ssh node175,
I use top command to check how many processes working on node 175 and find that
there are only one process working, not 8 processes.
Would you please tell me how to check the processes number on one node ?
Any help will be appreciated.
