The original specification for the Message Passing Interface (MPI) included language bindings for C and Fortran 77. C++ programs that used MPI were thus required to use the C bindings. With MPI-2, a C++ interface for all of MPI is specified. In this paper, we describe the design of the C++ interface for MPI and provide some of the history and motivations behind the design decisions.
