No messages on the command prompt. When I executed mpirun to launch notepad on the remote machine, It crashes again.
No information is ever printed to the command line unless I enter a bad password. The very first time I attempt to use mpirun to launch a process on the remote machine, I get an indefinite hang (I let it run for several hours yesterday). Subsequently I get an abend dialog in about 3 seconds. My MPI application (Which just calls init and finalize) is at C:\bin which is in the system path on both machines, this is also the bin directory for the openmpi package. Is there anyway I can turn on logging, or do I need to go through and insert debug statements myself and recompile? Thanks!
