We have 2 machines, 36 cores each. When we run experiments with "mpiexec -n 2 -map-by node -hostfile ~/machines", powergraph uses only a single core on each machine. What should we do to exploit all the available (72) cores?
Maybe: "mpiexec -n 72 -map-by core -hostfile ~/machines"?
But I think that powergraph gives warning that "it is recommended to use only one process per machine".
So how can we take advantage of the multiple cores machines?
Thanks a lot, Michael.
