But following code only specifies Tesla. Is there any reason to specify in the code? List in the code https://github.com/DPDK/dpdk/blob/v22.03/drivers/gpu/cuda/cuda.c#L56-L71 GPUDirect RDMA GPUDirect RDMA is available on both Tesla and Quadro GPUs. https://docs.nvidia.com/cuda/gpudirect-rdma/index.html Thanks Atsushi SAKAI ^ permalink raw reply [flat|nested] 4+ messages in thread
