Hi Jeff,
I would be happy to use OpenMPI. However, I haven't been able to compile
OpenMPI correctly on ARMv7. When I try to compile it, OpenMPI says that it
cannot find the atomic operations for the specific architecture. I know it
is possible to overcome this by implementing the ARMv7 specific parts in the
OpenMPI libraries. The atomic primitives for ARMv7 already exist in Linux so
it should not be too difficult to do. Unfortunately, I currently don't have
this scheduled in.
I will take a look at getting it done may be after a few more months. Let me
know if you have any insight.
However, there have been quite a few implementations of LAM on ARMv7
platforms. Therefore thats an easier route for the time being.
Thanks,
Anirban
