InfiniBand being utilized by 210 out of 500 of the supercomputers listed at

BEAVERTON, Ore. – June 19, 2012 – The InfiniBand® Trade Association (IBTA), a global organization dedicated to maintaining and furthering the InfiniBand™ specification, today announced that, for the first time, InfiniBand has exceeded all other interconnect technologies on the TOP500 list of the world’s fastest supercomputers. The latest list, available at, was released June 18 and shows that InfiniBand is now being utilized by 210 out of 500 clusters listed.

InfiniBand growth in recent years includes:

  • From June 2008 – June 2012, the total number of InfiniBand-connected systems on the TOP500 list has grown dramatically with an increase of 72 percent from 122 to 210.
  • InfiniBand connects 40 percent of the world’s most powerful Petaflop systems on the list, 8 out of the 20 systems.
  • InfiniBand connects 25 of the 30 most efficient systems, including the top two.
  • 86 percent of the accelerator-based systems are connected with InfiniBand.

This growth highlights how InfiniBand is used to maximize computing and accelerator resources, as well as improves productivity and scalable performance.

FDR InfiniBand™ (Fourteen Data Rate, 14Gb/s data rate per lane) is the fastest growing interconnect technology on the TOP500 with a 10X increase in the number of systems versus six months ago. FDR InfiniBand addresses the market demand for increased performance in high performance computing, enterprise, cloud and Web 2.0 networks and is backward compatible with the previously specified InfiniBand speeds – SDR, DDR and QDR – and, together with PCI Express 3.0, provides a step up for clustering and datacenter interconnect throughput, efficiency, reliability, and scalability.

“InfiniBand has grown at an incredible rate in the past several years, as we continue to see demand for higher efficiency and lower latency across data centers,” said Bill Lee, InfiniBand Trade Association. “InfiniBand’s growth in HPC mirrors the growth we’re seeing for InfiniBand in the enterprise data center – and specifically for cloud and Web 2.0.”

Created in 1999, InfiniBand enables low processing overhead and is ideal to carry multiple traffic types (clustering, communications, storage, management) over a single connection. As a mature and field-proven technology, InfiniBand is used in thousands of data centers, high-performance computing clusters and embedded environments that scale from two nodes up to clusters with thousands of nodes.
Since June 1993, the TOP500 list has ranked the world’s most powerful computer systems according to the Linpack benchmark rating system twice a year. The list is publicly available at
