Detailed Description

This is the set of MPI functions that are currently implemented in BDMPI.

For each of these functions, BDMPI provides a variant that starts with the MPI_ prefix and a variant that starts with the BDMPI_ prefix. The calling sequence of the first variant is identical to the MPI specification whereas the calling sequence of the second variant has been modified to make it 64-bit compliant (e.g., replaced most of the sizes that MPI assumed that were int to either size_t or ssize_t).
