Subject: [OMPI users] Support for CUDA and GPU-direct with OpenMPI 1.6.5 an 1.7.2
From: Michael Thomadakis (drmichaelt7777_at_[hidden])

Hello OpenMPI,

I am wondering what level of support is there for CUDA and GPUdirect on
OpenMPI 1.6.5 and 1.7.2.

I saw the ./configure --with-cuda=CUDA_DIR option in the FAQ. However, it
seems that with configure v1.6.5 it was ignored.

Can you identify GPU memory and send messages from it directly without
copying to host memory first?

Or in general, what level of CUDA support is there on 1.6.5 and 1.7.2 ? Do
you support SDK 5.0 and above?

Cheers ...
