BeoMPI doesn't work with more than 3 nodes

[Carlos J. García Orellana]

Hello,

I want to work with BeoMPI in our cluster, so I have started with examples.
First, it doesn't work because I was using a wrong 'mpirun' script, after
that,
the 'cpi' example works fine with 1, 2 or 3 processors.

However, when I try to use more nodes, it doesn´t work, why?

Please, which is the right setup to work with BeoMPI?.

Thanks.

Carlos.

PD: Output of executing 'cpi' with 3 and 4 nodes (p4dbg=10)
