This patch series aims to enable Peer-to-Peer (P2P) DMA access in
GPU-centric applications that utilize RDMA and private device pages. This
enhancement is crucial for minimizing data transfer overhead by allowing
the GPU to directly expose device private page data to devices such as
NICs, eliminating the need to traverse system RAM, which is the native
method for exposing device private page data.
Please tone down your marketing language and explain your factual
changes. If you make performance claims back them by numbers.
Got it, thanks! I'll fix that. Regarding performance, we’re achieving
over 10x higher bandwidth and 10x lower latency using perftest-rdma,
especially (with a high rate of GPU memory access).
