Sebastian,
If possible, I strongly suggest you look into CUDA 4.1 r2 and using Rolf
vandeVaart's MPI CUDA RDMA 3). Your life will be MUCH easier.
Having used GPUDirect1 in the last half of 2010, I can say it is a pain
for the 9 - 14% gain in efficiency we saw.

To what extent is distributed MPI_Graph (MPI 2.2) supported in OpenMPI
1.5.x?
Version shows it is based on MPI 2.1., but there are other
references ...

How about instead of all the patches (r25758, r25762 and r25763) we just set
both LD_LIBRARY_PATH and DYLD_LIBRARY_PATH everywhere? One will get ignored on
Unix while the other on Darwin?
Another benefit will be to have a significantly cleaner...

We could - but the cmd line is already quite long, and that would make it
worse. Doesn't strike me as all that complicated.
