Stephan,
A couple things to try
Put -np 2 after -hostfile /home/stephan/mpd.hosts
put the command you want to run after -np 2
Good luck,
Doug Reeder

Dear all,
I wanted to compare MPICH and OpenMPI. MPICH works fine. So I
installed OpenMPI the same way (configure, make, make install). The
commands are found in the OpenMPI installation directory.
When I tried to run programs I was a little bit confused, that
there seems not to be a default hosts-file like in MPICH. I
included it in the command with "--hostfile".
When I now want to run my first test with
mpirun -np 2 --hostfile /home/stephan/mpd.hosts
I get the error-message:
orted: command not found
The "orted"-executable resides as well as the "mpirun"- and
"mpiexec"-executables in the directory /home/stephan/openmpi-
install. "orted" is also found by "which orted".
What might be the problem? How does "orted" work? I'm not conscious
about anything equivalent in MPICH...
Thanks in advance for your help!
Kind Regards
Stephan
