The C++ support in mpich has been provided by Indiana University (formerly the University of Notre Dame), and uses its own configure process (it also supports other MPI implementations). This version supports only the MPI-1 functions, and does not include support for the MPI-2 functions such as I/O or the functions for manipulating MPI_Info. Questions, comments, suggestions, and requests for additional information should be sent to [email protected]. Bug reports should also be sent to [email protected]. More information is available at the web site http://www.osl.iu.edu/research/mpi2c++/.
