NVIDIA GPUs want to GPUDirect RDMA feature. Must it use hardware RDMA NIC by Mellanox like ConnectX-5 NIC, or I can use other RDMA by other companies and adapt it to support GPUDirect feature. If so, what do I need to install?
Now, I make some RDMA NIC by myself and want to support GPUDirect RDMA feature with NVIDIA GPU. What should I do?
