This seems to highlight a possible bug in the MPI implementation. As I
suggested earlier, the credit management of the OpenIB might be unsafe.
To confirm this one last test to run. Let's prevent the OpenIB support from
being used during the run (thus Open MPI will fall back to TCP). I suppose yo
The debug version also hung, roughly the same amount of progress in the
computations (although of course it took much longer to make that progress in
comparison to the optimized version).
On the bright side, the idea of putting an mpi_barrier after the irecvs and
before the isends appears to ha
