Hello Jeff,

I finally found the time to test the new release of the intel c++ 9.1
compiler on my system, and unfortunately I have one of those systems
were it still doesn't seem to be working (Ubuntu 5.10, Intel C/C++
9.1.044, OpenMPI 1.1.2) :-(

Anyway I can still use it, by creating a communicator by myself, e.g.:
MPI::Intracomm com(MPI_COMM_WORLD);

Best Regards,
