Good question.
Rolf -- do you plan to bring cuda stuff to v1.7.x?

Yes, there currently is support in Open MPI 1.7 for CUDA. What is missing is
some improvements for internode transfers over IB which I still plan to check
into the trunk and then move over to 1.7.
Hopefully within the next month or so.
Ok , thank you Rolf ,
... so for me, for a 'relatively stable' version, I thank it's I will better
try to use the 1.7.X series no ?
REM : This CUDA on IB part will come, I suppose, with the next CUDA5.0 driver ,
not yet released ...
A+
