Product Description

The IMSL Fortran Numerical Library version 5.0 integrates the world-renowned IMSL F90 Library with the IMSL Fortran 77 Library into a single, cohesive package.

The IMSL Fortran Library includes new powerful and flexible interface modules that allow for the use of advanced Fortran syntax and optional arguments throughout, while still providing full backward compatibility. These interface modules simplify and speed coding while improving quality by reducing the likelihood of mistakes. They also facilitate development of simpler Fortran applications while providing full depth and control for experienced programmers. Also included are a collection of new numerical algorithms and expanded support for SMP parallel processing.

The strength and precision of the IMSL Numerical Libraries have been evolving steadily for over three decades. Each subroutine and algorithm has undergone rigorous testing and quality assurance, providing users with more time to focus on their application.

The IMSL Fortran Library bundled with Absoft compilers for Windows and Macintosh OS X is directly available from Absoft. For Windows, the Absoft Pro Fortran Compiler Suite with IMSL is only available for single users on single systems up to 4 CPUs. For MacIntosh OS X, the Absoft Pro Fortran Compiler Suite with IMSL is available for single users on single systems and will soon be available for floating users, systems greater than 4 CPUs, and Clusters.

NOTE: IMSL Fortran Licenses for Absoft compilers for floating users on Windows, or for use on Windows systems greater than 4CPUs, or for Windows Clusters are not available at this time.

What's New

IMSL Fortran Library version 5.0 includes many new features:

New Faure Sequence Routine

• Computes a low-discrepancy sequence, which is used in Quasi Monte-Carlo analysis

New GARCH Routine

• Used to model time series data, such as the price of oil or interest rates

SMP/OpenMP Support

The IMSL Fortran Numerical Library offers expanded SMP support for a number of parallel processing environments. Computationally intensive algorithms in the areas of linear systems and matrix manipulation, eigensystem analysis, and fast Fourier transforms (FFTs) leverage SMP capabilities on a variety of systems.

MPI Enabled

IMSL Fortran Numerical Library provides a dynamic interface for computing mathematical solutions over a distributed system via Message Passing Interface (MPI). MPI enabled routines offer a simple, reliable user interface.
