Visual Numerics' IMSL® Fortran Numerical Library 5.0 Now Available for Intel^® Visual Fortran Compiler, Professional Edition, for Windows

Optimized High-Performance Numerical Analysis for Fortran Developers

San Ramon, CA - April 2, 2004 - Visual Numerics, Inc., a leading provider of numerical analysis and visualization software, today announced that the Visual Numerics IMSL® Fortran Numerical Library 5.0 is now available for the Intel^® Visual Fortran Compiler, Professional Edition, for Windows, announced by Intel Corporation earlier today. The capabilities of Visual Numerics' IMSL Fortran Numerical Library with the newest edition of the Intel Visual Fortran Compiler allows Fortran application developers to take advantage of robust mathematical and statistical algorithms optimized for Intel's compiler technology. Fortran developers can now build high-performance data analysis applications on Microsoft Windows-based systems using Intel^® Pentium^®, Intel^® Xeon™ and Intel^® Itanium^® 2 processors.

"Visual Numerics is committed to providing high-performance analytics to the Fortran community," said Phil Fraher, COO of Visual Numerics. "By working with industry leaders like Intel, we can continue to innovate our Fortran-based mathematical and statistical libraries, ensuring that the Visual Numerics IMSL Fortran Numerical Library continues to be the solution of choice within the high-performance computing community."

"The availability of our newest Intel Visual Fortran Compiler, Professional Edition, for Windows is exciting news for the Fortran community," said Jon Khazam, general manager of Intel's Software Products Division. "Intel's compiler technology and Visual Numerics' advanced mathematical and statistical algorithms offer an outstanding combination of development capabilities for Fortran programmers in industry, academia and research."

With the growing importance of business analytics and the need to develop more robust numerical analysis applications, availability of Visual Numerics' IMSL Fortran Numerical Libraries for the Intel Visual Fortran Compiler, Professional Edition, for Windows is a significant development for Fortran programmers. This shows Intel's and Visual Numerics' commitment to offer a comprehensive development environment available for high-performance analytics on Intel Architecture-based systems. Developers can take advantage of this solution to deliver powerful computing applications for a range of numerical analysis-intense industries including finance, life sciences, research, aerospace, manufacturing, and education, as well as high-performance computing audiences.

IMSL Fortran Numerical Library 5.0 For decades, Visual Numerics' IMSL Fortran Numerical Libraries have provided industry-leading analysis routines to Fortran developers in high-performance computing through partnerships with top compiler vendors such as Microsoft, Digital Equipment Corporation, Compaq, Hewlett-Packard, Absoft and Lahey. Unlike other libraries, the IMSL Fortran Numerical Library 5.0 is the only comprehensive library of mathematical and statistical algorithms for Fortran developers available in one cohesive package with complete backwards compatibility. The solution combines the powerful and flexible interface features of the Fortran language with the performance benefits of both distributed memory and shared memory multiprocessing architectures.

In addition to IMSL's popular and easy-to-use naming conventions, the IMSL Fortran Numerical Library version 5.0 uses the latest Fortran protocol throughout to include applicable optional arguments, which saves time and reduces complexity in programming. Visual Numerics has also added new optimization functionality and statistical time-series algorithm codes, making it the most comprehensive set of Fortran libraries available and supported in a single package.
