[Llvm-bgq-discuss] Details behind MPI wrapper for bgclang++

[Jack Poulson]

Hi Hal,

As far as I can tell, there are only two distinct wrappers in the
/home/projects/llvm/mpi/clang/bin folder, mpicc and mpicxx, and all of the
others are simply symlinks to them. Is it possible that I am
misunderstanding?

I am using the mpicxx wrapper.
