Introduction to HSL| HSL Archive |
The HSL Archive HSL (formerly the Harwell Subroutine Library) is a collection of ISO Fortran codes for large scale scientific computation written by members of the Numerical Analysis Group and other experts. As the library has evolved, many of the older packages have been superseded by newer versions, with increases in functionality or speed of execution.
Since October 2000, HSL has been divided into two parts, the main library, and an archive. The HSL Archive comprises packages that have either been superseded by more modern codes, or that we no longer felt able to support. While the main library continues to be a commercial product (although available without charge, for academic purposes, by UK academics), HSL Archive codes are now available without charge to anyone, so long as they are not then incorporated into a commercial product; the latter is, of course, still permitted subject to a commercial licence. No support will be available for the Archive, nor will any responsibility be taken for results derived from Archive packages.
Access to the Archive is by means of a short-lived individual password-controlled account. Potential users are asked for brief details of the use they intend to make of the package(s) they aim to download. Users are also asked to accept a conditions-of-use form, and are not permitted to divulge their userid and password to anyone else, nor to distribute any codes they obtain to a third party.
