The OpenFabrics Alliance (OFA) today announced 224 TOP500* supercomputers are using OpenFabrics Software (OFS) in their high performance computing (HPC) clusters, including two of the top 10. Clusters using OFA’s OFS driver stacks and application libraries achieve the highest performance of all clusters using standard interconnects.

According to the recently published list, OFS is present in the following:

• 224 clusters, 45% of the TOP500 list
• All 10 of the standards-based Petascale systems
• 86% of the accelerator-based systems

“The results from the TOP500 are a clear indication that OFS adoption continues to grow and is the leading open source software stack for running applications over InfiniBand, iWARP and RoCE,” said Jim Ryan, chairman, OFA. “The success of OFS is due to the hard work of OFA members and users whose mission is to identify and implement the highest-performing interconnect in the industry.”

OpenFabrics Software delivers remote DMA (RDMA) data transfer and kernel bypass to improve server efficiency and application performance for high-performance computing and data center environments running InfiniBand, iWARP or RoCE. Better application performance delivers a better return on not just the interconnect investment, but by making servers more efficient, OFS enables a better return on the entire data center investment. Additionally, better server and application performance enables data centers to use fewer servers leading to increased energy efficiency and reduced power consumption.

*The TOP500 list is published twice a year and ranks the most powerful and advanced supercomputer performance and architectures.

About the OpenFabrics Alliance

The OpenFabrics Alliance (OFA) is a 501(c) (6) non-profit company that develops, tests, licenses and distributes the OpenFabrics Software (OFS) – multi-platform, high-performance, low-latency and energy-efficient open-source RDMA software. OpenFabrics Software is used in business, operational, research and scientific infrastructures that require fast fabrics/networks, efficient storage and low-latency computing. OFS is free and is included in major Linux distributions, as well as Microsoft Windows Server 2012. In addition to developing and supporting this RDMA software, the Alliance delivers training, workshops and interoperability testing to ensure all releases meet multivendor enterprise requirements for security, reliability and efficiency.
