Using the modules software (modules.sourceforge.net) works pretty
well for managing multiple mpi flavors. You still need to put each
mpi flavor's bin, lib, and include files in uniquely named paths,
then modules lets you put the appropriate mpi flavor in your path for
each application. It t

I am sure. I have separate VMware-instances installed in order to
avoid any interdependencies.
FWIW, you might not want to comment out this line, but rather move up
any OMPI setup to *before* this line (so that it is processed both
during interactive and non-interactive logins).
The check for a non/interactive login may well be there for a reason;
there may well be things past that

I am sure. I have separate VMware-instances installed in order to avoid any

Hi,
Have you checked the .bashrc or /etc/bash.bashrc file on the machine. We
have seen this problem before on both Debian and Ubuntu systems. If you find
the following line:
# If not running interactively, don't do anything
[ -z "$PS1" ] && return
It means that the remainder of the file is not p
Make sure you're using the "right" mpirun. If you have both MPICH and
Open MPI installed, you need to install them into the different
directories.
As for not finding the "orted" on the remote nodes, it simply means
that your PATH / LD_LIBRARY_PATH is not set properly on the remote
nodes.
Hi Jodi,
thanks for the quick answer!

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,

Try to make sure wether your host file has the correct
