OFED

"The OpenFabrics Enterprise Distribution (OFED)/OpenFabrics Software is open-source software for RDMA and kernel bypass applications. OFS is used in business, research and scientific environments that require highly efficient networks, storage connectivity and parallel computing. The software provides high performance computing sites and enterprise data centers with flexibility and investment protection as computing evolves towards applications that require extreme speeds, massive scalability and utility-class reliability.

OFS includes kernel-level drivers, channel-oriented RDMA and send/receive operations, kernel bypasses of the operating system, both kernel and user-level application programming interface (API) and services for parallel message passing (MPI), sockets data exchange (e.g., RDS, SDP), NAS and SAN storage (e.g. iSER, NFS-RDMA, SRP) and file system/database systems.

The network and fabric technologies that provide RDMA performance with OFS include: legacy 10 Gigabit Ethernet, iWARP for Ethernet, RDMA over Converged Ethernet (RoCE), and 10/20/40 Gigabit InfiniBand.

The OFED stack includes software drivers, core kernel-code, middleware, and user-level interfaces. It offers a range of standard protocols, including IPoIB (IP over InfiniBand), SDP, SRP, iSER, RDS and DAPL (the Direct Access Programming Library). It also supports many other protocols, including various MPI implementations, and it supports many file systems, including Lustre and NFS over RDMA."
