Artur,
Thanks - that worked. However, I need to run across several nodes (each
node with 100 processes). Any thoughts? Is this a OS issue - I am running
Fedora Core 5 64-bit.

Hi Ben,
I had similar problem on Suse 10.1 and Fedora 4. On suse 10.2 the
problem disappear.
But you can overcome this.
1) boot you lam with "lamboot -v lamhost" where in the lamhost you have
all nodes required
for example: if you need to simulate 100 nodes on one physical cpu then
in lamhost you would have: localhost cpu=100
2) run your code with comand:
mpirun -ssi rpi crtcp C ./executabe
In may case with Lam MPI 7.1.2 it was OK. Let me know if it works also
in your case.
