QLogic TrueScale InfiniBand Integrates With NVIDIA Tesla GPUs to Drive New Levels of Power Efficiency in High Performance Computing
QLogic and NVIDIA Team With NCSA to Achieve Number Three Ranking on Green500 HPC Computing List

ALISO VIEJO, Calif., Mar 10, 2011 (GlobeNewswire via COMTEX) -- QLogic Corp. (Nasdaq:QLGC) today announced that a cluster using NVIDIA Tesla graphics processing units (GPUs), QLogic(R) InfiniBand(R) switches and adapters and operated by the National Center for Supercomputing Applications (NCSA) achieved a number three ranking for MFlops/watt on the Green500 list of the world's top supercomputers.

Launched in 2006, the Green500 ranks the most energy-efficient supercomputers in the world using performance-per-watt to encourage HPC vendors and users to deploy more cost-effective computing systems. The NCSA's hybrid cluster incorporated Intel Core i3 2.93Ghz dual core processors with NVIDIA Tesla C2050 GPUs and QLogic TrueScale InfiniBand solutions, producing a score of 933.06 MFlops/watt -- nearly four times more efficient than average supercomputers.

"We wanted to expand the frontiers of computational science, and the combination of NVIDIA Tesla GPUs with QLogic TrueScale InfiniBand fabrics is enabling this exploration," said Professor Wen-mei Hwu of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign. "In collaboration with NCSA's Innovative Systems Laboratory, the scaling and power efficiency from this combination of technologies has helped to place us near the top of the Green500 list."

"The high performance per watt of Tesla GPUs has made them the architecture of choice for modern supercomputing, as evidenced by the presence of several GPU supercomputers in the Top 10 of the Green500," said Sumit Gupta, product line manager, Tesla business at NVIDIA. "QLogic's TrueScale InfiniBand architecture, coupled with Tesla GPUs, is key to helping increase overall system performance and efficiency of the NCSA cluster."

QLogic's newest TrueScale InfiniBand software release does not require Linux kernel patches or special InfiniBand drivers to integrate with NVIDIA Tesla GPUs, making it very easy to install and maintain GPUs for HPC applications.

"Our interoperability with NVIDIA Tesla GPUs is another demonstration of how easily QLogic TrueScale InfiniBand fabrics support the most advanced cluster performance technologies," said Joe Yaworski, director of global alliances and solution marketing for QLogic. "These results show how our development teams are continually pushing the envelope to create the easiest, most efficient, and most scalable integration of technologies to make real-world differences in cluster scaling and efficiency."
