InfiniBand Momentum on the TOP500 Continues with 37 Percent Annual Growth Driven by Mellanox Performance-Leading Interconnect Solutions

Connecting the Majority of Worldwide PetaScale Systems, Mellanox InfiniBand Delivers Highest Efficiency and Scalability for High-Performance Computing

ISC’10 Hamburg, Germany – June 1, 2010 – Mellanox® Technologies, Ltd. (NASDAQ: MLNX; TASE: MLNX), a leading supplier of end-to-end connectivity solutions for data center servers and storage systems, today announced that its InfiniBand adapters and switch solutions demonstrated the highest growth on the TOP500 in the last two years. As reported in the 35th edition of the TOP500 list, the growth rate of Mellanox InfiniBand-connected systems represents more than 41 percent of the TOP500. Mellanox InfiniBand enables the highest system efficiency and utilization, up to 96 percent, and provides users with the best return on investment for their high-performance computing server and storage infrastructure computing requirements.

Mellanox ConnectX® InfiniBand adapters and switch systems based on its InfiniScale® IV switch silicon provide the scalable, low-latency, and power-efficient interconnect for the world’s fastest supercomputers, representing 50 percent of the Top10, 64 percent of the Top100, and the majority of the Top300 systems. Mellanox end-to-end 40Gb/s InfiniBand solutions deliver the leading performance and utilization for the most power efficient systems on the list.

The total number of InfiniBand-connected CPU cores on the TOP500 list has grown 73 percent, from 1.04 million in June 2009 to 1.8 million in June 2010. This growth highlights the increasing demand for InfiniBand as a way to maximize computing resources, productivity and performance in the world’s fastest computer systems.

“Mellanox’s end-to-end 40Gb/s connectivity provides the most scalable, reliable, and highest performance solution for demanding compute applications around the world delivering not only the highest return on investment, but also the lowest power consumption,” said Eyal Waldman, president, chairman and CEO of Mellanox Technologies. “We are experiencing the growth of InfiniBand in the high-performance computing markets and are now seeing its adoption in additional markets such as financial, database, virtualized data centers, Web 2.0 and Cloud Computing. InfiniBand has passed the early stage of adoption as a server and storage interconnect and is now entering into a growing number of mainstream vertical markets.”

“Advancements in multicore CPU architectures and the rise in GPU computing are placing greater demands on server and storage interconnects for higher bandwidth and lower application latencies,” said Jie Wu, Research Director, Technical Computing at IDC. “The results on the TOP500 list are a clear indication that Mellanox InfiniBand solutions have been gaining traction by many supercomputer buyers. New technology solutions developed by Mellanox, such as application offloads and GPU cluster efficiency enhancements, will continue to address the market demand for higher performance and improved efficiency.”

Published twice a year and publicly available at, the TOP500 list ranks the world’s most powerful computer systems according to the Linpack benchmark rating system. The TOP500 list is a respected industry report that indicates usage trends in computing and interconnect solutions.
