Are you still supporting ch3:sock?

We are, although we have chosen not to support a small subset of the MPI-3 functionality in ch3:sock, such as shared memory windows.

It's a pedantic detail, but MPI-3 says that shared memory is supported on a communicator returned by Comm_split_type. For ch3:sock, we return MPI_COMM_SELF, so technically we do support shared memory windows, but only on that process :-D. -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji
