Abstract

The paper describes the current version of mpi++, a C++ language binding for MPI, that includes all of the collective services, and services for contexts, groups and communicators as described in Chapter 4 and 5 of the MPI standard. The code for mpi++ has been tested on a Sun Sparc workstation and an Intel Paragon. Segments of a mpi++ program implementing a parallel algorithm is introduced to illustrate the Collective class hierarchy. The paper also shows how mpi++ deals with other collective operations (e.g., reduction), attribute caching, groups,and communicators. The class hierarchy of mpi++ is presented and briefly explained.
