Automatic deployment of interoperable legacy code services

The Grid Execution Management for Legacy Code Architecture (GEMLCA) enables exposing legacy applications as Grid services without re-engineering the code, or even requiring access to the source files. The integration of current GT3 and GT4 based GEMLCA implementations with the P-GRADE Grid portal allows the creation, execution and visualisation of complex Grid workflows composed of legacy and nonlegacy components. However, the deployment of legacy codes and mapping their execution to Grid resources is currently done manually. This paper outlines how GEMLCA can be extended with automatic service deployment, brokering, and information system support. A conceptual architecture for an Automatic Deployment Service (ADS) and for an x-Service Interoperability Layer (XSILA) are introduced explaining how these mechanisms support desired features in future releases of GEMLCA.

Symposium: Editing Political Diaries

The witness seminar was held in December 1991 at the Institute of Historical Research in London. It examined some of the key issues surrounding the editing of political diaries, including what to edit, the motivation of the diarist and the value of diaries to historians. Peter Catterall of the ICBH was in the chair. The three principal speakers were Ruth Winstone, editor of Tony Benn's diaries, David Brooks, editor of the diary of Sir Edward Hamilton, and John Barnes, co‐editor with David Nicholson, of the diary of Leo Amery. Other contributors included Jad Adams (biographer of Tony Benn), Kathleen Burk (co‐author of a study of the 1976 IMF crisis), Philip Williamson (editor of the diary of William Bridgeman), M.R.D. Foot (an editor of the Gladstone diaries), and Stuart Ball (editor of the diary of Sir Cuthbert Headlam).
