The Portland Group Adds IMSL Fortran Numerical Library for Windows


Popular Visual Numerics library now available as an option with PGI multi-core optimizing parallel Fortran compilers

Portland, ORE, March 2008 - The Portland Group™, a wholly-owned subsidiary of STMicroelectronics (NYSE: STM) and a leading supplier of compilers and development tools for High-Performance Computing, today announced that the IMSL® Fortran Numerical Library from Visual Numerics®, Inc. is available from The Portland Group for PGI’s line of multi-core optimizing parallel Fortran compilers running under the Microsoft Windows operating systems.

The IMSL Fortran Library is a comprehensive set of popular mathematical and statistical functions. Software developers can use the pre-written functions included within the library as building blocks in their software applications. This library frees programmers from the necessity of developing their own equivalent functions. Both the library and numerical algorithms within it have a reputation for quality and performance across an extensive range of compilers and operating system environments.

“The IMSL Fortran Library is one of the most widely used math libraries for technical computing applications on Windows and is very popular with our Linux customers,” said Douglas Miles, director, The Portland Group. “We’ve been working with Visual Numerics to bring this valuable resource to PGI’s complete line of Windows compilers including support on native Windows, the Windows Subsystem for Unix Applications (SUA), and within applications built using PGI Visual Fortran.”

“We are pleased to be working closely with The Portland Group to bring the IMSL Fortran Library to their latest generation of Windows Fortran compilers,” said Tim Leite, Director of Corporate Development at Visual Numerics. “PGI compilers are popular in technical and high-performance computing, a key target market segment for the IMSL Libraries. With this new product we extend to PGI and HPC developers on Windows the same high standards for quality and reliability that IMSL Libraries are known for worldwide.”

PGI compilers and tools are used predominantly on 64-bit and 32-bit Linux, Mac OS X and Microsoft Windows workstations, servers, and clusters based on microprocessors from AMD and Intel. The Portland Group’s flagship product suite, PGI Workstation, includes compilers and tools for building, debugging and profiling parallel 64-bit and 32-bit Fortran, C and C++ applications within a UNIX- and Linux-compatible development environment. Key compiler features include automatic and user-directed parallelization and optimizations for extracting maximum performance from the new generation of multi-core processors. In addition to extensive UNIX migration features, the PGI Visual Fortran compiler is available fully integrated with Microsoft’s Visual Studio 2005 development environment. The key advantages of PGI compilers and tools can be found on The Portland Group web site at A trial version of PGI compilers is available for download at Registration is required.

The IMSL Numerical Libraries have been the cornerstone of high-performance and deep computing as well as predictive analytics applications in science, technical and business environments for well over three decades. These embeddable mathematical and statistical algorithms, written in C, C#, Java™, and Fortran, are used in a broad range of applications. The IMSL Libraries are regarded as the most sophisticated, flexible, scalable and highly accessible technology available for numerical analysis in the most important mainstream programming environments in use today
