Changing control_slaves to true did not make thing work but it did provide me with a bit more info on this. Enough to figure things out. Now when I run i get a message about "rcmd:socket: Permission denied" : Starting server daemon at host "hpcp7782" Server daemon successfully started with task id "1.hpcp7782" Establishing /hpc/SGE/utilbin/lx24-amd64/rsh session to host hpcp7782 ... rcmd: socket: Permission denied /hpc/SGE/utilbin/lx24-amd64/rsh exited with exit code 1 reading exit code from shepherd ... timeout (60 s) expired while waiting on socket fd 4 error: error reading returncode of remote command -------------------------------------------------------------------------- A daemon (pid 31961) died unexpectedly with status 255 while attempting to launch so we are aborting. There may be more information reported by the environment (see above). This may be because the daemon was unable to find all the needed shared libraries on the remote node. You may set your LD_LIBRARY_PATH to have the location of the shared libraries on the remote nodes and this will automatically be forwarded to the remote nodes. -------------------------------------------------------------------------- -------------------------------------------------------------------------- mpirun noticed that the job aborted, but has no info as to the process that caused that situation. -------------------------------------------------------------------------- mpirun: clean termination accomplished [hpcp7781:31960] mca: base: close: component rsh closed [hpcp7781:31960] mca: base: close: unloading component rsh So it turns out the NFS mount for SGE on the clients had option "nosuid" set which does not allow the qrsh/rsh SGE binaries to run because they are setuid. Got rid of the "nosuid" and now things work just fine. Thank you for the help Rene
