Remote Direct Memory Access
May 14, 2024
3 minute read
Remote Direct Memory Access (RDMA) is a computer networking technique that allows a computer's network interface controller (NIC) to access the memory of another computer's NIC directly, without involvement of the operating system or other software running on the computers. RDMA allows for very high-speed data transfer rates, and is often used in high-performance computing (HPC) and other applications where fast data transfer is critical.
What is RDMA?
RDMA is a transport protocol that enables direct access to the memory of a remote computer. This is in contrast to traditional network protocols, which require the data to be copied from the sending computer's memory to the network, and then from the network to the receiving computer's memory. RDMA eliminates this copying process, which can significantly improve performance for applications that need to transfer large amounts of data.
