New Numerical Algorithms for Chemical Researchers - Release of the NAG Library for SMP and Multicore

Chemical researchers seeking better use of the processing power of multicore computer systems in addition to an easy way to migrate existing applications to multi-processor architectures can now download the new NAG Library for SMP and Multicore ( from Numerical Algorithms Group (NAG).

Mathematical and statistical algorithms optimized for performance on multicore architectures have become key to progress in various aspects of chemometrics, modeling, and other chemical engineering research, especially at the nano-scale.

The NAG Library for SMP and Multicore contains over 1600 routines, including more than 100 new ones for this release. A complete listing of these routines can be found at

As Dr. Hartmut Schmider of the computational support team of the High Performance Computing Virtual Laboratory at Queen's University, Kingston, Ontario says, “The NAG Library is very good for work on multiple cores because of the reliable parallel design of the algorithms. But it is also because of the common interface for both serial and multicore libraries. This enables users to speed up their code on many multiple core architectures with greatly reduced effort.”

David Cassell, NAG product marketing manager, reports, “Most current processors are multicore, and can provide benefits when programmed with parallel techniques. In fact, if you do not use routines tuned for multicore architectures applications are now likely to execute more slowly. The NAG library for SMP and Multicore also has been designed to make it easy to move those applications that currently call serial routines into the parallel world, by the use of common calls and common documentation. This means users can quickly gain the benefits of parallel performance.

“A wide array of users worldwide converting their applications to multicore environments continue to look to NAG’s technical experts for algorithms for multicore application development, because NAG algorithms have the reputation for being robust and reliable. The program speed-up that parallel computing promises is not without special challenges -- for debugging, managing race conditions, synchronization, etc. NAG’s computational expertise has long been relied on by supercomputing sites worldwide to find solutions to these challenges. Many of the routines in the NAG Library for SMP and Multicore have foundations in this work.”
