Does the Geforce GTX 780 (kepler) gpu support GPUDirect RDMA with a third party device (Mellanox network card)?
I have been looking for information about this but cant find a definitive answer. In some places it says that only Tesla cards support this features and in other places it says “Kepler-class GPU” which I think would include the GTX 780.
I’ve requested such a list from support, but even support wasn’t able to help me. The best I could find is, if it says Tesla (since Kepler?), Yes, if anything else, No. Please correct me if other (cheaper) cards are also supported.
“…applications running on NVIDIA Tesla™ and Quadro™ products”.
“All you need is CUDA Toolkit v4.0 and R270 drivers (or later) and a system with two or more Fermi- or Kepler-architecture GPUs on the same PCIe bus”.
GPUDirect is a range of technologies. RDMA/Async for example is for GPUs on different nodes which has different requirements. It takes quite some digging to find the different nuances and requirements.
