I don't think I can easily replicate the compile problem.  Could someone (Rich?) please volunteer to accept a patch and attempt to compile it rather than have me spin my wheels trying to install an old version of MPI on something?

I’d just like to say using MPI_IN_PLACE is a great way of saving on memory copies and there is a reason why newer versions of MPI have it; it’s better.

Constantly making compromises to support old versions is (in my opinion) bad practice.
I’d vote (and I know that nobody agrees with me) to not support older MPI versions. Let people upgrade their MPI rather than bloat code by patching for this.

I feel quite strongly about this and will happily contribute a CMake check for MPI_IN_PLACE which will tell the user at cmake time that their MPI is unsupported and they need to upgrade.
