Yes, it's supported, but it's a little different than what "-n" usually does in mpiexec, where it means the number of processes. For 'jsrun', it means the number of resource sets, which is multiplied by the "tasks per resource set" specified by "-a" to get
the MPI process count. I think if we can specify that "-a 1" is part of our "mpiexec", then we should be OK with using -n as PETSc normally does.<br></div></blockquote><div><br></div><div>jsrun does not run with just -n on SUMMIT. I have found that it works with adding -g 1. </div></div></div>
