# sample Makefile for MPI (OpenMPI implementation)
#
# first make sure mpicc references an MPI compiler 
#
# usage examples:
#   "make hello" to compile "hello.c" to "hello" 
#
# note that you must first set up to include MPI in your environment
#   (command "module load openmpi-default" or "openmpi-latest" -- I use
#   the former)
