Rdma throughput
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. WebRemote Direct Memory Access (RDMA) capability. RDMA allows for communication between systems but can bypass the overhead associated with the operating system …
