NAG Library for SMP & Multicore

Description

Unrivalled functionality, increased speed and heightened performance for shared memory parallelism

The NAG Library for SMP & Multicore is the largest commercial numerical algorithm library developed to harness the huge performance gains from the shared memory parallelism of Symmetric Multi-Processors (SMP) and multicore processors.

Many of the algorithms, or routines, in the Library are specifically tuned to run significantly faster on multi-socket and multicore systems.

Why should I use the NAG Library for SMP & Multicore?

The NAG Library for SMP & Multicore has proven scalability, speed and correctness making it easy to exploit the power of SMP and multicore systems without requiring the user to modify their code. It contains all the powerful, robust and flexible algorithms in the NAG Library but is specifically optimized for SMP and multicore systems, so by purchasing the multicore version of the NAG Library you're future proofing your numerical software investment as your hardware grows.

Specialized multicore functionality

  • Dense and Sparse Linear Algebra
  • Fast fourier transforms (FFTs)
  • Random Number Generators
  • Quadrature
  • Partial Differential Equations
  • Interpolation
  • Curve and Surface Fitting
  • Correlation and Regression Analysis
  • Multivariate Methods
  • Time Series Analysis
  • Financial Option Pricing
  • Dense linear algebra (LAPACK)
  • Sparse iterative solvers
  • Sparse direct solvers (based on SuperLU)
  • Sparse iterative eigensolvers (based on ARPACK)

Other areas that benefit from tuned routines

  • Ordinary differential equations (ODEs)
  • Optimization
  • Multivariate statistics
  • Linear algebra

Replacing NAG Fortran Library routines with their multicore equivalents

The NAG Library for SMP & Multicore is based on, and includes, the full functionality of the NAG Fortran Library so the arguments list and routines names are identical. This provides an easy upgrade path because the same code can call a routine that performs the same function, in either the Fortran Library or the NAG Library for SMP & Multicore. The distinction between the two is only made when the final code is linked to a library. Applications that reference a NAG Library routine can therefore take advantage of the performance improvement simply by recompiling and linking your code on a multicore system.

No specialist parallel programming knowledge is required to apply the multicore techniques to your code. The parallelism is carried out automatically and transparently in certain distinct regions within the routines.

Documentation

Supporting Documentation

This release of the NAG Library for SMP & Multicore has identical functionality and subroutine interfaces as the latest release of the NAG Fortran Library. The NAG Library for SMP & Multicore now uses the same documentation and version numbering scheme as the NAG Fortran Library.

The Library is organized into Chapters - each being documented with its own Introduction and Contents list followed by a comprehensive document for each function detailing its purpose, description, list of parameters and possible error exits. Example programs and results are also supplied. All examples are available on-line to facilitate their use as templates for the users' calling programs.

The NAG Library for SMP & Multicore Manual

The complete NAG Library for SMP & Multicore Manual, Mark 24 can be viewed on-line in the following formats:

  • HTML: The full manual available as HTML (using HTML5 features such as MathML and SVG in suitable browsers);
  • PDF: the same manual as above, consisting of many PDF files, may be browsed using PDF bookmarks or via the HTML table of contents pages;
  • Single file PDF: the manual as a single PDF file;
  • ZIP file: The archive as a ZIP file (152 MB);
  • Windows html help: Windows html help version as a single file;
    (Note: due to windows security restrictions the help file may not be read directly from the internet. Save a copy to your local disk, and then read the local copy. Also depending on the Windows version installed you may need to unblock files copied from the internet before they may be used (right click on the help file and select properties then select the "unblock" button).

Advice on viewing and navigating the first three formats can be found in the Online Documentation help document. You are strongly advised to read this document if you wish to try the XHTML+MathML format.

The NAG SMP Library Manual, Mark 23 and prior

Previous releases of the NAG SMP Library Manual are still available: Mark 23 and Mark 22.

Installer's Notes and Users' Notes

Support documentation for the installation and use of each implementation of the NAG Library for SMP & Multicore is available.

Product Availability

The following table provides a simple mechanism by which you can determine the most appropriate NAG Library for SMP and Multicore implementation for your needs. The table is organized by grouping implementations firstly by operating system and secondly by compiler; you simply select the combination appropriate to the system that you use. The most important information that you can derive from this is the NAG product code which is located in the rightmost column of each record and is a 10 character string beginning FS.
