Does this code work with other MPI implementations? I'm still trying
to track the problem down, but it looks like an invalid request is
cropping up in a call to MPI_Wait and that is causing the
segmentation fault. There may be another issue, but I need to do a
bit more testing to be sure.

You are right, there is a bug in the code for algo=3 and algo=4.
This bug was harmless with lam/mpi.
Now open/mpi works fine !!!
