Hi Since i upgraded from open-mpi .2.2 to open-mpi 1.2.5 and had to reinstall my machine aim-plankton (fedora 8 instead of fedora 6) open-mpi doesn't work correctly anymore:
When i start an application from aim-plankton to run on an other machine, it seems to hang (no output, not even from debug-daemons). [jody@aim-plankton ~] $ mpirun -np 1 --debug-daemons --host aim-nano1.uzh.ch MPITest However, this action causes the creation of an orted process on the other machine: [jody@aim-nano1 ~] $ ps ax | grep orted 7680 ? Ss 0:00 /opt/openmpi/bin/orted --bootproxy 1 --name 0.0.1 --num_procs 2 --vpid_start 0 --nodename aim-nano1.uzh.ch --universe j...@aim-plankton.uzh.ch:default-universe-9422 --nsreplica 0.0.0;tcp://130.60.126.111:60229 --gprreplica 0.0.0;tcp://130.60.126.111:60229 7772 pts/0 S+ 0:00 grep --colour=auto orted The other way round it works without problems [jody@aim-nano1 ~] $ mpirun -np 1 --debug-daemons --host aim-plankton MPITest Daemon [0,0,1] checking in as pid 9759 on host aim-plankton [aim-plankton.uzh.ch:09759] [0,0,1] orted: received launch callback [aim-plankton.uzh.ch]I am #0/1 global [aim-plankton.uzh.ch:09759] [0,0,1] orted_recv_pls: received message from [0,0,0] [aim-plankton.uzh.ch:09759] [0,0,1] orted_recv_pls: received exit ssh works perfectly in both directions, with or without login. My open-mpi setup worked well before. What happened since was an upgrade to open-mpi 1.2.5 on all machines, and a change from fedora 6 to fedora 8 on aim-plankton, the badly behaving machine. Does anybody have a suggestion where i should start looking? Thank you Jody
