#
# Makefile to build MPI examples in fortran, C and C++ for Blue Gene/L
#
# For Fortran, the MPI include file is mpif.h
# For C, the MPI include file is mpi.h
# For C++, also needs mpi.h header file (place before stdio.h, iostream.h -- if used):
#   #include mpi.h
#   #include stdio.h
#   #iostream.h
#
# In addition, a -DHAVE_MPI_CXX flag must be included in the compile process
# to turn on the C++ portion in the mpi.h header file.
