WebHistory. InfiniBand originated in 1999 from the merger of two competing designs: Future I/O and Next Generation I/O (NGIO). NGIO was led by Intel, with a specification released on 1998, and joined by Sun Microsystems and Dell.Future I/O was backed by Compaq, IBM, and Hewlett-Packard. This led to the formation of the InfiniBand Trade Association … WebGPU Direct RDMA removes the system memory copies, allowing the GPU to send data directly through InfiniBand to a remote system. In practice, this has resulted in up to 67% reductions in latency and 430% increases in bandwidth for small MPI message sizes [ 1 ].
