ALISO VIEJO, Calif., Nov. 9, 2010 (GLOBE NEWSWIRE) -- QLogic Corp. (Nasdaq:QLGC) today announced that its 7300 Series QDR InfiniBand® host channel adapters (HCAs) have established new world records for non-coalesced message rate performance at both host and cluster levels. Based on the QLogic® TrueScale architecture, the 7300 Series achieves cluster message rate performance of over 86 million messages per second, which is more than 2.3 times higher than comparable InfiniBand adapters. In addition, a QLogic 7300 Series QDR host channel adapter with servers based on Intel's Xeon 5600 processor achieved a world record, non-coalesced message rate performance of 23.7 million messages per second, 7.8 times higher than comparable InfiniBand offerings.
Message rate performance directly relates to the performance of an HPC application and its ability to scale. QLogic TrueScale's message rate means that applications will run faster and clusters will be able to scale more effectively. Using an end-to-end solution based on QLogic InfiniBand products, customers will be able to run their applications faster as well as receive better price-per-performance results.
"HPC application performance is based in large part on the message rate performance at the host and cluster levels," said Joseph Yaworski, director of global alliances and solution marketing, QLogic. "These world record rate performance numbers show that QLogic TrueScale InfiniBand is the best architecture for running a wide range of customer and ISV-developed applications at optimal performance."
Tests were run using The Ohio State University message bandwidth benchmark. The system configuration was a fourteen node cluster with two switches which were linked to each other. Each switch was connected to seven nodes. A single, inter-switch link was used to measure the maximum cluster level message bandwidth for the various InfiniBand solutions.
