One Cohesive
Package of Advanced Numerical Algorithms
Lying at the heart of the IMSL Numerical Libraries are the comprehensive
and trusted IMSL mathematical and statistical numerical algorithms.
The IMSL Libraries are the gold standard for comprehensive libraries
of numerical computing algorithms that software developers can embed
into their applications. The latest version of the IMSL Fortran
Numerical Library is comprised of all of the trusted algorithms
from past versions of the IMSL family of Fortran libraries, including
the IMSL F90 Library, the IMSL FORTRAN 77 Library, and the IMSL
parallel processing features. In addition, utilities are included
to simplify large-scale computing with the ScaLAPACK library. For
a complete list of the algorithms included in the IMSL Fortran Numerical
Library, please see the Function Catalog.
Powerful
Interface Modules
The IMSL Fortran Numerical Library includes new powerful and flexible
interface modules for all applicable routines, which accomplish
the following:
- Allows users to utilize the fast, convenient optional arguments
of the modern Fortran syntax for 100% of the relevant algorithms
in the library, allowing for greater control and faster, simpler
code development
- Only require a short list of required arguments for each
algorithm to facilitate development of simpler Fortran applications
- Provide full depth and control via optional arguments for
experienced programmers
- Reduce development effort by checking data-type matches
and array sizing at compile time
- With operators and function modules, provide faster and
more natural programming through an object-oriented approach
- A simple and flexible interface to the library routines
speeds programming and simplifies documentation
Complete
Backward Compatibility
For over two decades, the IMSL Fortran Numerical Library has maintained
full backward compatibility with all previous versions of the Library.
No code modifications are required for existing applications that
rely on previous versions of the IMSL Fortran Numerical Library.
Calls to routines from the IMSL FORTRAN 77 Library with the F77
syntax continue to function.
Fully Tested
Visual Numerics has developed over three decades of experience in
testing IMSL numerical algorithms for quality and performance across
an extensive range of the latest compilers and environments. Visual
Numerics works with compiler partners and hardware partners to ensure
a high degree of reliability and performance optimization. This
experience has allowed Visual Numerics to refine its test methods
with painstaking detail. The result of this effort is a robust,
sophisticated suite of test methods that allow the IMSL user to
rely on the numerical analysis functionality and focus their bandwidth
on their application development and testing.
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.
The IMSL Fortran library provides a number of
MPI-enabled routines with an MPI-enhanced interface that provides:
- Computational control of the server node
- Scalability of computational resources
- Automatic processor prioritization
- Self-scheduling algorithm to keep processors continuously
active
- Box data type application
- Computational integrity
- Dynamic error processing
- Homogeneous and heterogeneous network functionality
- Use of descriptive names and generic interfaces
- A suite of testing and benchmark software
