Slidecast: HPC Networking with OpenFabrics and InfiniBand – An Update from SC12

In this video, Bill Lee from IBTA and Rupert Dance from the Open Fabrics Alliance discuss the latest developments in high performance networking at the SC12 conference in Salt Lake City.

This week the OpenFabrics Alliance (OFA) 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 system

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.”
