Is is not impossible, but normally the standard redirection ">" works with  
(open)mpi out-of-the-box. If you cannot find the output file it may  
indicate that the working directory used by mpirun is not the directory in  
which you are looking for the output file; see the "Current Working  
Directory" section of mpirun manual for details. You can set the working  
directory explicitly using the option -wd "/path/to/directory" to settle  
this issue.

Another issue I've had sometime, that could cause problems similar to the  
one you've had, is related to two conflicting version of mpi. The mpirun  
instance on the master node tries to start the wrong mpirun on the other  
nodes. Use the --prefix option to be sure this is not your case (syntax  
example: "mpirun --prefix /opt/openmpi-1.3.1" without "/bin/")

Best regards.
