Hi Jens

What this says is that the system was unable to launch your processes on the specified machines. The usual reason is a lack of ssh authority on the remote machines. You might check the following FAQ to see if it is of help:

http://www.open-mpi.org/faq/?category=rsh

Let us know if that solves the problem. I'm assuming that you are using an rsh/ssh launcher and not in some other kind of cluster - if that's incorrect, please let us know.

        I did the following run with openmpi1.0.2:
        
        mpirun -np 8 -machinefile ompimachinefile ./hello_world_mpi
        
        and got the following errors
        [stokes:00740] [0,0,0] ORTE_ERROR_LOG: Not implemented in file
        rmgr_urm.c at line 177

        rmgr_urm.c at line 365
        [stokes:00740] mpirun: spawn failed with errno=-7
        
        What should I do to track the error or to get rid of it?
