Summary on Grant Application Form
Automatic Differentiation (AD) is a set of techniques for transforming scientific modelling and/or simulation codes so as to produce accurate (truncationfree) derivative values at low computational cost, exploiting user knowledge of application structure while avoiding edious and error-prone manual rewriting. This in turn facilitates the extension of scientific and/or engineering codes to incorporate parameter optimization, data assimilation, and multidisciplinary design. As well as being of immediate practical utility, AD also provides a conceptual framework for systematic analysis of themodelling process, facilitating the transfer of such techniques between application domains.This network proposal is based upon extending and enhancing an informal network which already exists, and which is organised from NOC (Hatfield) and RMCS (Shrivenham), the two major centres of activity for Automatic Differentiation (AD) in the UK. The UK already has an internationally leading profile in AD theory, however the leading-edge application to engineering domains of the AD theory developed in the UK has historically occurred mainly in the USA and Japan. This proposal seeks to enhance the existing AD network in a way whichwill increase the level of contact between ADtheory, toolbuilders, and potential application areas, to the point where the UK can act asa focal player in the European arena.
