This week Voltaire announced an interesting piece of software to enhance the performance of Open MPI-based applications by as much as 30% according to the company. From the release at HPCwire
Voltaire OMA works transparently over any interconnect technology that works with Open MPI, including InfiniBand and 10 Gigabit Ethernet (10GbE). It improves inter- and intra-node communication by freeing up intra-node resources resulting in faster performance for leading HPC applications. This can translate to greater productivity and time-to-market for companies in industries ranging from manufacturing, oil and gas, research, weather and government that rely on HPC applications to meet their business objectives.
Voltaire has conducted benchmark tests with OMA and several leading commercial HPC applications based on Open MPI. One of these benchmarks revealed that Voltaire OMA improves performance of OpenFOAM tutorial benchmarks by as much as 28 percent. This is in addition to running popular micro-benchmarks such as MPI OSU and IMB (Pallas). Voltaire OMA integrates seamlessly with Open MPI and requires no special tuning to achieve the desired performance improvements.
