# The OMPI_CC environment variable must be defined, otherwise mpicc will
# fail with a complaint about being unable to locate gcc.
#
# Be sure to `export OMPI_CC=/usr/bin/clang`
#
# Dependencies:
# 	OpenMPI must be installed
# 	pthreads must be available
#
# Make variables:
# 	MT: Specify the number of workers to use. Defaults to 1 if unspecified
# 	FAST: If defined, use optimization and vector unrolling optimizations
# 	      If not defined, disable optimizations and include debugging symbols
#
# Examples:
# 	`make MT=4 FAST=1`
