As Rusty mentions, this should work for mpd.  The gforker version of 
mpiexec has a bug in the current release that sends both stdout and stderr 
to stdout, but you should be able to redirect stdout to a file or to 
/dev/null .  For our nightly tests, we redirect stdout and stderr to a 
file.  Is there a particular problem that you are having?  We'd like this 
to work just like it was any other Unix command.
