PathScale, developer of innovative software and hardware solutions to accelerate the performance and efficiency of Linux® clusters, and ParTec, developer of Linux Cluster performance management solutions, have announced a technology partnership that will enable HPC users to further enhance the speed and performance of commodity-priced AMD Opteron processor-based Linux clusters. PathScale's new InfiniPath InfiniBand cluster interconnect is being integrated with and optimized for operation with ParTec's ParaStation4, a robust and efficient cluster middleware solution that consists of high-performance communication tools and a sophisticated software management layer.

The seamless interoperability of these two leading technologies will be demonstrated at the International Supercomputer Conference on 22 June through 24 June in Heidelberg, Germany. PathScale is located in Booth B-03. The ParTec Cluster Competence Center is located in Booth I-01.

PathScale's InfiniPath HTX Adapter is the industry's lowest-latency Linux cluster interconnect for message passing (MPI) applications. InfiniPath plugs into standard HyperTransport technology-based HTX slots on AMD Opteron processor-based servers. Optimized for communications-sensitive applications, InfiniPath has posted an all time record-low MPI latency of 1.32 microseconds and a peak unidirectional bandwidth of 952 MB/s, with half of this peak bandwidth achieved at a message size of 385 bytes (streaming). For applications that rely on IP traffic, InfiniPath achieves TCP/IP throughput of 583 MB/s with a one-way latency of only 6.7 microseconds.

"The new PathScale InfiniPath interconnect is setting new standards for high-performance Linux cluster communications," said Hugo R. Falter, COO of ParTec. "Its strength in multi-CPU, multi-core systems means that global organizations searching for faster, more reliable, more cost effective HPC systems will deploy it in large or very large clusters where the capabilities of ParaStation4 will be critical."

ParTec's ParaStation4 is a highly-sophisticated and reliable management and communication middleware solution for high performance Linux clusters. The optimized network communication of ParaStation4 increases the performance of distributed applications, ensures rapid cluster deployment and increases stability throughout the entire lifetime of the cluster.

"The partnership between PathScale and ParTec furthers our mission to make high performance Linux clusters ubiquitous," said Art Goldberg, COO of PathScale. "By tightly coupling the high performance software stack for InfiniPath with ParaStation4, organizations deploying large Linux clusters will get their systems up and running more quickly and will be able to manage them more effectively."
