*** This mail mainly targeted at Brian and George ***

Debian maintainer Manuel Prinz raised an idea to me this morning:

The Debian community compiles and tests Debian on a huge range of hardware 
platforms.  It's been a long-standing issue that Open MPI doesn't support all 
of them (e.g., MIPS, ARM, ...).  Specifically, we don't have assembly to 
support all of those platforms.

The Debian community asks: if building with a recent GCC on one of these 
platforms where OMPI doesn't have native assembly, can we fall back to the GCC 
intrinsic atomics?

    https://svn.open-mpi.org/trac/ompi/ticket/2495

Additionally, there's then OpenPA project from Argonne that supports a bunch of 
atomics on a bunch of platforms.  George told me at one point that he didn't 
think it was sufficient for Open MPI's needs.  Do we know if that's still true?
