MOUNTAIN VIEW, CA – PathScale has optimized its EKOPath™ Compiler Suite and InfiniPath™ low-latency interconnect to provide enhanced support for the new Dual-Core AMD Opteron™ processors.

A free trial download of the compiler is available at

AMD's (NYSE:AMD) revolutionary Direct Connect Architecture with two cores on the same die along with memory and HyperTransport™ technology I/O, enables superior performance per dollar and performance per watt for 32- and 64-bit x86 applications. In close collaboration with AMD's engineers, PathScale has optimized version 2.1 of the EKOPath Compiler Suite specifically for Dual-Core AMD Opteron processors. These improvements include code generator performance tuning for OpenMP applications and significantly improved compilation times.

PathScale 2.x compilers enable AMD and its system partners to produce unprecedented performance benchmark results on dual-core x86 systems, such as the recent SPEC® CPU2000 benchmarks submitted by HP and AMD which use PathScale compilers exclusively to optimize their Linux results.

"Working closely with PathScale and other technology partners, AMD has set new performance standards for x86-based 64-bit computing," said Pat Patla, director, server/workstation marketing, Microprocessor Business Unit, Computation Products Group, AMD. "AMD dual-core technology is a natural extension of AMD64's innovative Direct Connect Architecture. PathScale's EKOPath compilers and InfiniPath interconnect products allow users to deploy Dual-Core AMD Opteron™ processor-based systems for maximum application performance and greater user productivity."

A 30-day free trial of the PathScale EKOPath Compiler Suite is available at

PathScale's innovative InfiniPath HTX Adapter for Infiniband™ was designed specifically with Dual-Core AMD Opteron processors in mind. InfiniPath is the industry's lowest latency Linux cluster interconnect, delivering SMP-class performance to commodity-priced Linux clusters while leveraging important standards such as HyperTransport technology, InfiniBand, MPICH and AMD64 Direct Connect Architecture.

InfiniPath is the only cluster interconnect that implements a HyperTransport™ technology-based tunnel architecture to better accommodate two and four socket servers. This is essential for servers designed with multiple dual-core processors, since the number of available HyperTransport technology interfaces in these systems may be limited. InfiniPath is also unique with nine virtual ports per chip for user applications implemented directly in hardware, meaning that each InfiniPath adapter efficiently supports up to eight CPUs with one additional port for the Linux operating system. Other interconnects do not implement this capability in hardware which can lead to performance scalability issues.

The InfiniPath HTX Adapter is planned for availability later this spring. For details, visit
