Yes, they are supported in the sense that they can work together. However, if you want to have the ability to send/receive GPU buffers directly via MPI calls, then I recommend you get CUDA 4.1 and use the Open MPI trunk.

Hi,

I am using Open MPI 1.4.5 and I have CUDA 3.2 installed.

Anyone knows whether CUDA 3.2 is supported by OpenMPI?

Thanks
