Hi Rob, just in case if the MPICH team needs an account on P775 for testing/debugging purposes, we can easily arrange it. Just let us know and we will open access to you. We would love to have MPICH3 working on our "monster" machine. With best regards Victor. _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
