PathScale Ships EKOPath™ Compiler Suite 2.0 for AMD® Opteron™ and Intel® Xeon™ EM64T Processor Families

Award-winning compilers for Linux Clusters deliver up to 40 percent faster performance, OpenMP 2.0 support, and a new advanced serial debugger

Sunnyvale, Calif. – January 11, 2005 – PathScale, a developer of software and hardware solutions to accelerate the performance and efficiency of Linux® clusters, is now shipping Version 2.0 of its industry-leading EKOPath compilers for C, C++, and Fortran 77/90/95. The new version is available immediately at no additional cost to all current PathScale subscribers. A 30-day free trial download is available to new customers at

"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."

EKOPath Version 2.0 can produce performance improvements of 20 percent or more for many HPC applications when compared to earlier PathScale compilers, and up to 40 percent faster applications performance over alternative compiler products. More Information is available at

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 ACML 2.5 core math library to ensure the highest possible math function performance from applications running on AMD64 platforms.

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.
