Hi Christian
Somehow your program was not attached to the message.
In any case, you didn't say anything about your "machinefile" contents.
You need to list the nodes you want to use there.
The command line will be something like this:
mpirun -np 4 -machinefile my_machinefile canon
"man mpirun" may help you with the details.
(I assume you are using the mpirun that comes with mpich1.)
Having said that, I suggest that you move from MPICH-1 to
OpenMPI or to MPICH2.
MPICH-1 (mpich-1.2.7p1) is old, not maintained or supported anymore,
and often times breaks in current Linux kernels.
The MPICH developers also recommend upgrading to MPICH2.
OpenMPI and MPICH2 are free, easy to install, stable, up to date,
and more efficient than MPICH1.
Upgrading to one of them is likely to avoid more trouble later,
specially with your tight deadline.
See:

I hope this helps,
