QLogic Sets Records for Host and Cluster Based Message Rate Performance in HPC Environments

By DE Editors

QLogic Corp. says 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 company says its 7300 Series achieves cluster message rate performance of more than 86 million messages per second. 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, according to the company.

Message rate performance directly relates to the performance of an HPC application and its ability to scale. QLogic says its TrueScale’s message rate means that applications will run faster and clusters will be able to scale more effectively.

“HPC application performance is based in large part on the message rate performance at the host and cluster levels,” says 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 14-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.
