RDMA

(Remote Direct Memory Access) A communications protocol that provides transmission of data from the memory of one computer to the memory of another without involving the CPU. InfiniBand, Virtual Interface (VI) and RDMA Over IP are all forms of RDMA. Implemented in hardware on the network adapter (NIC), RDMA techniques have been developed to accommodate the ever-increasing network speeds. See DMA, InfiniBand, VI and RDMA Over IP.

"Using hardware compute accelerators such as NVIDIA T4 GPUs and Mellanox's RDMA networking solutions has proven to boost application performance in virtualized deployments."
WDMA, derived from RDMA, places a higher weight on rating disagreement in parse items by squaring the denominator inside the sum, thus reducing the weight associated with the items rated by many users.
The OpenFabrics Alliance (OFA) is a 501(c) (6) non-profit company that develops, tests, licenses and distributes the OpenFabrics Software (OFS) multi-platform, high performance, low-latency and energy-efficient open-source RDMA software.
Jim Pinkerton, a partner architect in Microsoft's File Server Technologies development group, compared the ability to use RDMA over Ethernet or InfiniBand to that of the high-speed storage protocol Fibre Channel, in that a network interface card is used to offload network protocol traffic from a server's CPU.
New adapter cards with both RDMA and ToE hit the market in 2004, with vastly improved latency performance.
There was a "huge emotional gulf" between what he had done and murder, the RDMA asserted.
"Deep neural network-based AI for autonomous vehicles and other machine learning training requires massive amounts of networking bandwidth and RDMA to connect the GPU systems to each other and to storage, which is why NVIDIA DGX AI servers and DRIVE Constellation driving simulation solutions take advantage of Mellanox InfiniBand and Ethernet networking connectivity," said Charlie Boyle, vice president and general manager of DGX systems at NVIDIA.
They provide performance for NVMe over RoCE (RDMA over Converged Ethernet), InfiniBand, and TCP/IP, and include smart offloads for storage including NVMe-oF, erasure coding, and T10-DIF data integrity signatures.
iSER is an industry standard protocol that uses RDMA technology to eliminate the network processing overhead, while preserving full compatibility with the widely used iSCSI protocol.
This paper proposes a new data model, named Key-Value-Links (KVL), to help in-memory store utilizes RDMA efficiently.
