NEW ORLEANS, Nov. 15, 2010 (GLOBE NEWSWIRE) -- QLogic Corp. (Nasdaq:QLGC) today announced that its Quad Data Rate (QDR) InfiniBand® switches and adapters have proven to be a key force in providing unprecedented levels of high performance computing (HPC) for unclassified research. Specifically, QLogic 12000 Series switches and 7300 Series adapters are now providing the QDR InfiniBand infrastructure for four high performance computing (HPC) clusters, code named Sierra, Muir, Ansel and Titan, totaling more than 4,000 nodes and associated switch ports, at the Lawrence Livermore National Laboratory (LLNL). The mission of LLNL not only involves national security, but also the application of advanced science and technology to the important issues of today. Sierra is part of LLNL's Multi-programmatic and Institutional Computing (M&IC) program and supports "Grand Challenge" and other unclassified research efforts at LLNL. Grand Challenge projects are collaborative research efforts with academic institutions and other labs that push the envelope of "capability" computing, which dedicates powerful HPC systems to taking on the most difficult and complex problems. "Our performance requirements escalate faster than we can address them year after year," said Brian Carnes, program director for M&IC at LLNL. "With these latest results, Sierra would rank just inside the top 25 of the world's most powerful supercomputers on the current TOP500 list. Sierra boosts Livermore Computing's total unclassified computing resources to more than 870 teraflops. Combined with some of the world's most talented simulation scientists, Sierra will enable Livermore Computing to further advance our leadership in science and technology." "Sierra's performance and scalability outperform all other platforms for several of our critical simulation codes," said Matt Leininger, deputy for advanced technology projects at LLNL. "This translates into higher productivity, more cost-effective computing, and accelerated scientific discovery." "Livermore Computing was able to double its HPC resources with an affordable, standards-based solution from QLogic and Dell," said Jesse Parker, vice president and general manager, Network Solutions Group, QLogic. "This is primarily due to the fact that unlike competitive offerings, QLogic QDR InfiniBand solutions are designed to deliver superior message rates and protect cluster investments by delivering increased application performance as computing resources are scaled across multiple dimensions."
