Hello Emanual,
can you actually log in using rsh without submitting a password?
I would rather use the ssh-based login using public-keys to login. This is
definitely more secure but in Your first mail, You said, ssh wouldn't work
either?

So, the question from the mpirun_debug.out-file is, what IP-addresses do
node01 and node02 have, is the local 10.0.0.1 node01, while 10.1.0.1 is
node02?
Maybe the route on node01 is not correct to node02?

Hope, this helps.

Thanks,
Rainer
