WebIn computing, remote direct memory access ( RDMA) is a direct memory access from the memory of one computer into that of another without involving either one's operating system. This permits high-throughput, low- latency networking, which is especially useful in massively parallel computer clusters . Overview [ edit] WebRDMA is a feature that enables network adapters to transfer data directly between each other without requiring the main processor of the system to be part of that transfer. This results in lower latency and lower processor utilization.
