WebOne of the desirable features associated with InfiniBand, another network fabric technology, is its Remote Direct Memory Access (RDMA) capability. RDMA allows for communication between systems but can bypass the overhead associated with the operating system kernel, so applications have reduced latency and much lower CPU utilization. WebThe NFS/RDMA server was first included in the following release, Linux 2.6.25. In our testing, we have obtained excellent performance results (full 10Gbit wire bandwidth at minimal client CPU) under many workloads. The code passes the full Connectathon test suite and operates over both Infiniband and iWARP RDMA adapters. Getting Help¶
WebAlthough InfiniBand Architecture is relatively new in the high performance computing area, it offers many features which help us to improve the performance of communication subsystems.
