Oh, stupid me! On Debian /etc/pam.d/rsh does not contain session required pam_limits.so After adding this line it worked. I was sure that the limits were set since mpirun -np 4 bash -c ulimit -l always returned unlimited, but rsh node02 ulimit -l just showed 32 which is indeed way too small. The additional bash call seems to change the limits and fooled me this way. Just another question: Is is possible to use a 32 Bit machine as head node (without being involved into the computations)? When I try to run a program using mpirun from the 32 Bit machine I get [headnode:32560] [0,0,0] mca_oob_tcp_recv_handler: \ invalid message type: 0 and the debug output shows [node01:01330] [0,0,1]-[0,0,0] mca_oob_tcp_peer_recv_blocking: \ recv() failed with errno=104 which means "Connection reset by peer". In between the 64 Bit machines it works fine now. Thanks, Emanuel
