Visual Numerics® Releases Version 7.0 of the IMSL® C Library With Unprecedented Performance and Depth of Algorithms

Extensive Parallelization of Algorithms Ensure Strong Numerical Application Performance in Multi-Core Environments

HOUSTON, TX--(Marketwire - November 13, 2008) - Today, Visual Numerics, Inc., a 38-year producer of advanced numerical analysis and visualization software, announced the immediate availability of version 7.0 of the IMSL C Numerical Library. This release provides improved performance in multi-core and many-core environments through the parallelization of numerous algorithms using OpenMP and greater depth of functionality via new and updated algorithms.

"This version 7.0 release of the IMSL C Library is one of our most ambitious product updates in recent years," said Dr. Ed Stewart, IMSL Product Manager, Visual Numerics. "The performance improvements and new analytic capabilities should benefit both our extensive user community and developers looking for new analytic solutions."

Recent articles and analyst reports document the strong revenue and unit sales growth for multi- and many-core systems. In September, the research firm IDC reported 10% growth for high-performance multi-core systems for the second quarter of 2008 alone. These high-performance systems though pose a challenge for software developers who need to transition from programming for single-core processors to multiple cores. To help alleviate this challenge, Visual Numerics has parallelized numerous algorithms in the IMSL C Library version 7.0 release using OpenMP technology. By using these parallelized algorithms, developers can write applications that take best advantage of the performance capabilities of multi-core systems.

"Developers can increase business productivity and keep costs down by taking advantage of the full performance of multi-core technology in high-performance computing applications," said Ed Turkel, manager, product marketing, Scalable Computing and Infrastructure organization, HP. "The combination of HP BladeSystem c-Class blade servers and HP ProLiant rack-based servers with the algorithms provided by Visual Numerics allows customers to run their applications with increased performance, while lowering costs and conserving power."

"We are pleased to see IMSL C Library multi-core enablement for Windows HPC Server 2008," said Vince Mendillo, director of HPC marketing at Microsoft. "This offering extends Microsoft's developer ecosystem to leverage the latest high performance computing technology for concurrent computing, while taking advantage of Visual Numerics algorithmic technology."

The many new and updated algorithms in the IMSL C Library version 7.0 provide unique numerical analysis techniques to customers solving analytic problems in finance, business intelligence, data mining and other areas. For example:

--  Finance customers will benefit from a new Feynman-Kac algorithm that
    solves Black-Scholes problems; a powerful Genetic Algorithm solver to solve
    problems such as identifying the best technical indicator from hundreds or
    thousands of indicators that will best predict future stock behavior; and
    Naïve Bayes classification techniques to, for example, classify financial
    news feeds to text mine for information.
--  Business intelligence and data mining software developers can also
    leverage Genetic Algorithms for optimization and Naïve Bayes for
    classification and text mining problems. In addition, new classification
    capabilities in the Neural Network algorithm and new ways to select
    Auto_ARIMA models offer additional classification and forecasting
--  Other new and updated functions, such as faster normal random number
    generation and new Kochanek-Bartels Cubic Splines, Non-central chi-square,
    and Non-central students' T PDFs will benefit customers in finance, BI and
    many other industries.
