RDMA:s prestandafördelar och begränsningar: kopylös överföring från HPC.

Zero-Copy Network Creation and Resource Efficiency Remote Direct Memory Access (RDMA) enables data transfer from one computer’s memory to another’s memory without affecting either computer’s operating system. This capability enables high-speed, low-latency network creation, which is especially important for large, parallel computer clusters.

InfiniBand and the Future of Uncertainty Although RDMA is superior to many technological alternatives in high-performance computing, its commercial future is uncertain.
