ALISO VIEJO, Calif., July 24, 2007 (PRIME NEWSWIRE) -- QLogic Corp. (Nasdaq:QLGC), a leader in networking for storage and high performance computing, today announced that the widely used message passing interface (MPI) library for InfiniBand known as MVAPICH (pronounced as em-vah-pich) developed by The Ohio State University, is now enhanced to run on QLogic(r) InfiniBand host channel adapters (HCAs). Now HPC sites using this popular software can significantly boost connectivity performance with QLogic InfiniBand HCAs, which deliver the lowest latency and highest message rates in the industry.

"With software innovations like MVAPICH, which optimizes the performance of InfiniBand cluster computing, research labs and commercial companies continue to benefit from the advantages of supercomputing," said Dhabaleswar K. (DK) Panda, professor of computer science and engineering at The Ohio State University and leader of the MVAPICH research team. "The QLogic InfiniBand HyperMessaging Architecture(tm) offers competitive performance with MVAPICH implementations."

The QLogic InfiniBand HyperMessaging Architecture delivers the highest message rate and highest effective bandwidth of any cluster interconnect available. It allows QLogic InfiniBand HCAs to support over 10 million messages per second, or 10X-MR. By achieving 10X-MR, QLogic InfiniBand HCAs delivers over 10 times more messages per second than any other cluster interconnect. Their unprecedented messaging rate also reduces network fabric congestion as the InfiniBand adapter will no longer be the network bottleneck.

"The Ohio State University has advanced supercomputing to new levels of affordable high performance with MVAPICH," said Roger Klein, vice president and general manager, QLogic Host Solutions Group. "Government and business users can now combine this prevalent MPI with the QLogic InfiniBand HyperMessaging Architecture for faster calculations than ever, which translates into faster results, a priceless advantage."

The MVAPICH software is available from and supported by The Ohio State University.
