*** 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?
