The following options can be use with the --enable-comms= option to target different communication interfaces:

<comm>	Description
none	no communications
mpi]	MPI communications using MPI-3 shared memory
mpi-auto	MPI communications with compiler CXX but clone flags from MPICXX

For the MPI interfaces the optional -auto suffix instructs the configure scripts to determine all the necessary compilation and linking flags. This is done by extracting the informations from the MPI wrapper specified in the environment variable MPICXX (if not specified configure will scan though a list of default names). The -auto suffix is not supported by the Cray environment wrapper scripts. Use the standard wrappers ( CXX=CC ) set up by Cray PrgEnv modules instead.
