Dear Xin, unfortunately, MXM is not avaiable on our cluster and admins won't install it. So, should I wait untill you repair 'ch3:nemesis:ib'? Actually, I would be happy even if my test-code starts working on my laptop :) Best regards, Victor _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
