Visual Numerics^® Announces IMSL® Numerical Library Support for HP’s Itanium^® 2-based Family of Products

Users of Linux on Intel^® Itanium 2-based HP systems can conduct high-performance numerical analysis with reliable, time-tested libraries

Phoenix, AZ (Super Computing “SC2003” Conference) – November 17, 2003 – Visual Numerics Inc., a leading provider of numerical analysis and visualization software, announced that the company will port its IMSL Numerical Libraries to HP Integrity^® servers and HP workstations, which use Intel’s flagship 64-bit Itanium 2 chip for the High Performance Computing (HPC) and Linux markets. The IMSL Libraries powered by Itanium 2 on RedHat^® Linux and the Intel C and Fortran compilers will provide HP users with industry-standard mathematics and statistics algorithms on one of the most advanced computing platforms available.

The combination of the industry-standard IMSL Libraries with an Itanium 2-based HP system running on a Linux OS will provide a critical foundation for performing complex computations in the scientific, life sciences, aerospace, investment, finance, government, and engineering markets. Its 64-bit architecture enhances performance by addressing vastly more memory than traditional 32-bit PC architectures and enabling computation of more complex problems. In addition, Linux is a platform well suited for research, modeling, design and visualization technologies.

“We’re committed to offering our customers the highest quality numerical analysis solutions, on the fastest, most widely used, high-performance computing platforms today,” said Phil Fraher, COO of Visual Numerics. “Our IMSL Library ports to HP’s Itanium 2-based systems will provide super computing users, in a range of markets, with the power to confidently perform advanced computational analysis and visualization.“

“Our customers demand reliable solutions that support our Itanium 2-based systems--HP Integrity servers and HP zx workstations,” said Winston Prather, vice president and general manager of the High Performance Technical Computing Division at HP. “Visual Numerics’ IMSL Libraries meet that demand for the application developers of sophisticated computationally intensive applications.”

About the IMSL Numerical Libraries
The IMSL Numerical Libraries are a comprehensive set of mathematical and statistical algorithms that programmers can embed into their C, Java™ and Fortran software applications. IMSL provides the expertise needed to develop and execute robust numerical analysis applications. This application allows engineers, scientists and researchers to manipulate simple to extremely large and complex datasets to detect and display patterns, trends, anomalies and other vital information that would otherwise be overlooked in their data.

Availability
The IMSL C Numerical Library port to Itanium2 will be available in December 2003. In addition, the Fortran version of the IMSL Numerical Library port for Itanium2 will be available in early 2004. For more information, contact Visual Numerics at http://www.vni.com/contact/worldwideoffices.html.
