International Supercomputing Conference 2004: PathScale's New AMD-64 Compiler Suite Certified as Interoperable With Streamline Computing's Distributed Debugging Tool for Linux Clusters

- Collaborative Engineering Effort Between PathScale and Streamline Results in More Comprehensive Development Environment -

SUNNYVALE, Calif. and HEIDELBERG, Germany, June 23 -- PathScale, Inc., developer of innovative software and hardware solutions to accelerate the performance and efficiency of Linux clusters, and Streamline Computing Ltd., a Warwick, UK-based developer of customized clustering solutions, have announced the mutual certification of their respective Linux compilers and debugger. Specifically, version 1.2 of the PathScale EKO Compiler Suite and version 1.7 of Streamline's Distributed Debugging Tool (DDT) have been updated, cross-tested and certified to be fully interoperable with each other.

PathScale and Streamline Computing are participating in the International Supercomputer Conference (ISC2004) in Heidelberg, Germany from June 23 to June 25. PathScale is exhibiting in the Advanced Micro Devices (AMD) booth.

“When AMD64 application developers combine the superior performance of the PathScale EKO Compilers with the industry’s easiest-to-use parallel debugging tool, they will find that creating parallel applications for Linux clusters is immediately faster and easier, resulting in more efficient and more scalable applications,” said Dr. Michael Rudgyard, president and CEO for Streamline.

The PathScale EKO Compiler Suite for Fortran 77/90/95 and C/C++ is the world’s highest-performance 64-bit compiler for Linux systems powered by AMD Opteron™ and Athlon64™ processors. Streamline’s Distributed Debugging Tool (DDT) is a comprehensive graphical debugger designed for the complex tasks associated with debugging scalar, parallel and multi-threaded code.

Both PathScale and Streamline are committed to accelerating the adoption of clustered computing for all types of high-performance applications,” said Scott Metcalf, president and CEO of PathScale. “Together, our two companies are providing AMD64 developers with best-of-breed integrated tools that dramatically speed time to deployment for parallel applications running on Linux clusters.”

Version 1.2 of the PathScale EKO Compiler Suite may be purchased from Streamline Computing or PathScale, or from PathScale FastPath Resellers worldwide starting on June 30, 2004. This new PathScale release will also provide support for SuSE 9.1 and Fedora Core 2, and significant performance improvements for both 64-bit and 32-bit applications.
