Welcome to the IFIP Working Group 2.5 on Numerical Software
In 1974 the International Federation for Information Processing (IFIP)
established the Working Group on "Numerical Software"
under the auspices of its
Technical Committee on "Software: Theory and Practice".
The group started with 13 members and has since grown to a
more than 30.
IFIP policy, members do not represent their countries, national
societies, or the like. The present chair is
The aim of Working Group 2.5 is to improve the quality of scientific
computation by promoting the development and availability of sound
Objectives within the scope of the Working Group
- Environment. The definition from a numerical standpoint of a set of hardware and
software features for a computing system.
- Tools. The development and improvement of programming languages
and other tools for numerical computation.
- Algorithms. The establishment of guidelines for
the assessment of numerical algorithms and their implementations.
- Software. The establishment of guidelines for
the preparation, interoperability, verification,
validation, documentation, distribution and maintenance of
- Data. The establishment of guidelines for
the validation, documentation, preservation, and distribution
of numerical data.
- Communication. The exchange of information concerning numerical
software and the determination of the needs of computer users.
The following mode of work has been established within WG 2.5:
- Working group meetings
The group meets roughly once a year
(39 meetings so far). At these meetings, areas of activity and the
proper means of achieving results are defined. Reports on current or
completed activities are given and discussed. The Working Group has met in
The next meeting is scheduled for
Shanghai, China, August 2013.
Most activities take the form of projects. One or
several members of the group assume the responsibility to pursue a
given subject matter in collaboration with other scientists in the
field. Results of projects are either published through standard
channels or, in special cases, may take the form of an IFIP-document.
A web page describing these projects is
- Working Conferences
This is a standard means of IFIP-activity:
50-70 experts meet to discuss and advance a narrow technical subject
area. The proceedings of a
appears as a book from the IFIP publisher.
