OpenMPI/OFED is the first software product layered on OFA’s OpenFabrics Enterprise Distribution (OFED) open software stack. It gives designers of ISR subsystems a choice of including standards-based Open MPI middleware without sacrificing performance. OFED, an open source software distribution containing a standard fabric access API, is widely adopted in the high performance computing (HPC) community. This fabric-independent and optimized implementation includes high bandwidth, low latency data transfer support. It enables OFED-based middleware packages, such as Open MPI, to run on embedded systems without sacrificing performance. This expands the impact and reach of OFED and its software ecosystem from HPC/server market segments to include the real-time, high performance embedded computer market. Open MPI/OFED middleware provides an abstraction layer between the hardware and the customer application. This not only enables user software to be leveraged from platform generation to platform generation, but also allows rapid code migration from HPC-based systems, such as high-end workstations and blade servers, to traditional embedded computer systems.
