WebJun 18, 2024 · Remote direct memory access (RDMA) is a solution that bypasses some of the major hardware and software bottlenecks in high-performance computing (HPC) systems. It offloads data movement from the central processing unit (CPU) and ensures direct placing of data to their final destinations, without extra copies. WebThe RDMA Resource Center contains briefs, videos, and more on the technology to improve network performance and support both RDMA iWARP and RDMA. 跳转至主要内容 切换导航
WebRDMA transmission works in NICs with three queues: Send Queue (SQ), Receive Queue (RQ), and Completion Queue (CQ). When an RDMA application starts to work, it must create its SQ, RQ, and CQ in the RDMA NIC, and registers regions in memory for its processing. The work scheduling unit of RDMA is a Queue Pair (QP), which consists of one SQ and one RQ. Webcess (RDMA) implements the entire transport logic in hardware network interface card (NIC) and allows di-rect access to remote memory, mostly bypassing CPU. Therefore, RDMA …
