Hi, Is there a way to limit the number of tasks started by mpirun? For example, on our 48-core SMP, I'd like to limit MPI jobs to a maximum of 12 tasks. That is, "mpirun -np 16 ..." would return an error. Note that this is a strictly interactive system; no batch environment available.
I've just quickly scanned the MCA parameters: ompi_info --param all all and couldn't find the answer to my question. Thanks! -- Best regards, David Turner User Services Group email: dptur...@lbl.gov NERSC Division phone: (510) 486-4027 Lawrence Berkeley Lab fax: (510) 486-4316
