This function is deprecated. It has been replaced with an MPI-2 attribute on MPI_COMM_WORLD - MPI_UNIVERSE_SIZE , which provides the same functionality. This function is (or effectively is) a wrapper to the replacement attribute, anyway. User programs should use the MPI-2 replacement attribute instead of this function.
Some functions are deprecated because their names did not conform to the stricter naming conventions of MPI-2; others are deprecated because they have been replaced with more flexible functionality.
