Hi Arthur,
According to the Intel® MPI Library for Linux* OS Reference Manual:
-perhost <# of processes >, -ppn <# of processes >, or -grr <# of processes>
Use this option to place the indicated number of consecutive MPI processes on every host in the group using round robin scheduling. See the I_MPI_PERHOST environment variable for more details.
-rr
Use this option to place consecutive MPI processes on different hosts using the round robin scheduling. This option is equivalent to -perhost 1. See the I_MPI_PERHOST environment variable for more details.
