@ Michael I did the following with openmpi 1.1 and 1.2 alphas now I get the following error. mpirun --mca pls_rsh_agent ssh -np 2 -machinefile ompimachinefile ./hello_world_mpi -------------------------------------------------------------------------- No available launching agents were found. This is an unusual error; it means that Open RTE was unable to find any mechanism to launch proceses, and therefore is unable start the process(es) in your application. -------------------------------------------------------------------------- [stokes:11293] [0,0,0] ORTE_ERROR_LOG: Not found in file rmgr_urm_component.c at line 190 Jens
