Hi Riccardo,
I have done this with helloworld.m, and info is always 0, which means no MPI
error. helloworld.m and mc_example2.m both work fine using the MPI_*
functions that don't use octave_comm.h, so I guess that the problem is
there. I would be happy to run any test code that could help to clear it up.
Cheers, Michael
