InfiniBand Continues Explosive Growth on June 2007 TOP500 List

Number of Supercomputers Using InfiniBand Interconnect Increases 230% in One Year
p align="left">INTERNATIONAL SUPERCOMPUTING CONFERENCE 2007, DRESDEN, GERMANY – JUNE 27, 2007 – Mellanox™ Technologies, Ltd. (NASDAQ: MLNX), a leading supplier of semiconductor-based, server and storage interconnect products, announced today that InfiniBand continues to be the fastest growing cluster interconnect according to the 29th edition of the TOP500 list of the world’s most powerful computers. 132 supercomputers (26% of the list) are connected with InfiniBand, 230% more than the 40 supercomputers on the June 2006 list, and 61% more than the 82 supercomputers reported on the November 2006 list.

InfiniBand-based clusters continue to take share from clusters using Ethernet and proprietary interconnect solutions as industry-standard InfiniBand is proven to deliver higher scalability, efficiency and performance, especially when connecting multi-core computing servers and storage systems. In particular, 20Gb/s InfiniBand usage on the list has increased significantly to 55 clusters from only a single cluster 6 months ago which highlights the fast adoption of 20Gb/s performance.

Published twice a year and publicly available at, the TOP500 list ranks the most powerful computer systems according to the Linpack benchmark rating system and is an industry respected report which indicates usage trends in computing and interconnect solutions. Highlights of InfiniBand usage on the June 2007 TOP500 list include:

  • All InfiniBand-based clusters utilize Mellanox switch silicon and well over 95% integrate adapters products based on Mellanox silicon
  • 8 of the top 20 most prestigious positions use InfiniBand – all based on Mellanox adapter cards and switch silicon
  • InfiniBand is the most used high-speed, low-latency interconnect and has the greatest increase in the rate of usage, used by 26% of the list
  • The average efficiency of all reported InfiniBand-based supercomputers is 71% -- significantly higher than the average efficiency of Gigabit Ethernet connected clusters at 54%
  • Higher performing InfiniBand-based supercomputers are replacing supercomputers using  proprietary interconnect technologies such as Myrinet (47% decline since June 2006) and lower-performing Gigabit Ethernet (19% decline since June 2006)
  • 20Gb/s InfiniBand usage has dramatically increased from zero entries on June 2006, to 55 systems on the current list (42% of the InfiniBand clusters)
  • 20Gb/s InfiniBand is widely used by multi-core systems as they impose high demands on the interconnect, and require a scalable and reliable I/O solution
  • InfiniBand is used by a diverse list of applications, from large-scale high-performance computing (government, universities, research) to commercial technical computing (semiconductor, automotive, mathematical computing, oil and gas, manufacturing, weather, and more) and enterprise data centers (transportation services, IT services, utility computing, food industry, financial services, and more)

“Clustering multi-core servers and storage systems demand an interconnect that provides low-latency, scalability and processor efficiency – all characteristics of InfiniBand making it the natural choice for high-performance computing applications,” said Eyal Waldman, president, chairman and CEO of Mellanox Technologies. “With the strong growth of 20Gb/s InfiniBand deployments, and with the expectation of 40Gb/s InfiniBand in the latter part of 2008, Mellanox-based InfiniBand accelerated systems will continue to deliver the ever-increasing performance needs of world leading research centers, universities and commercial data centers.”

Come Visit Mellanox at The International Supercomputing Conference, Dresden Germany, June 26-29, 2007
Located at booth #D27-30, Mellanox is demonstrating leading InfiniBand interconnect solutions during exhibition hours. Demonstrations include commercial applications that take advantage of InfiniBand interconnect as well as world-class MPI throughput over 20Gb/s InfiniBand adapters and Intel-based PCI Express 2.0 (5GT/s signaling rate) supported servers platforms.
