- Newest Version of Award-Winning PathScale EKOPath Compiler Suite Delivers Higher Performance, OpenMP 2.0, a New Advanced Serial Debugger and Complete Support for AMD(R) Opteron(TM) and Intel(R) Xeon(TM) EM64T Applications -

SUNNYVALE, Calif., Jan. 11 -- PathScale, developer of innovative software and hardware solutions to accelerate the performance and efficiency of Linux(R) clusters, is now shipping Version 2.0 of its industry-leading EKOPath compilers for C, C++, and Fortran 77/90/95. This new version is available immediately at no additional cost to all current PathScale subscribers. A 30-day free trial version is available to new customers by visiting

"The PathScale EKOPath Compiler Suite offers the world's fastest applications performance for 64-bit Linux clusters," explained Scott Metcalf, CEO of PathScale. "Developers targeting 64-bit Linux servers will realize immediate performance benefits by switching over to EKOPath 2.0. This new release can produce further performance improvements of 20 percent or more for many HPC applications when compared to earlier PathScale compilers."

The new version of the EKOPath Compiler Suite introduces several key functional enhancements including support for OpenMP 2.0 for Fortran, the industry-standard Application Program Interface (API) that allows programmers to parallelize applications on a multi-processor node. It also supports a PathScale-optimized AMD Core Math Library, ACML 2.5, to ensure the highest possible math function performance from applications running on AMD64 platforms.

In addition, PathScale EKOPath compilers now support the Intel Xeon EM64T 64-bit X86 architecture. This enables programmers to standardize on a single compiler suite for all 32- and 64-bit x86 computing applications. All PathScale compilers now include an advanced serial debugger known as Pathdb, the industry's only "backwards stepping" debugger.

In real-world application benchmark testing performed by beta users, Version 2.0 of the EKOPath Compiler Suite continues to extend its performance lead over alternative compiler products. This makes PathScale the clear choice for compiling 64-bit Linux applications and delivering maximum performance.
