#
|
|
# This Makefile fragment is meant to be included by packages
|
|
# that use any MPI implementation instead of one particular one.
|
|
# The available MPI implementations are "mpich" and "openmpi",
|
|
# or just whatever you have installed in the system (mpi wrapper
|
|
# compiler names are standardized).
|
|
#
|
|
# You have to decide on one implementation and stick to it. Especially
|
|
# with the native option, installing an MPI implementation from pkgsrc
|
|
# will break things for programs that you built before.
|
|
#
|
|
# User-settable variables:
|
|
#
|
|
# MPI_TYPE
|
|
# This value represents the type of MPI we wish to use on the system.
|
|
# Changing this value is only safe when you ensure that all MPI-using
|
|
# packages are re-built, and if switching to native, the MPI package
|
|
# from pkgsrc needs to be deinstalled first.
|
|
#
|
|
# Possible: mpich, openmpi, native
|
|
# Default: mpich
