Abstract
After a definition of e–science and the Grid, the paper begins with an overview of the technological context of Grid developments. NASA's Information Power Grid is described as an early example of a ‘prototype production Grid’. The discussion of e–science and the Grid is then set in the context of the UK e–Science Programme and is illustrated with reference to some UK e–science projects in science, engineering and medicine. The Open Standards approach to Grid middleware adopted by the community in the Global Grid Forum is described and compared with community–based standardization processes used for the Internet, MPI, Linux and the Web. Some implications of the imminent data deluge that will arise from the new generation of e–science experiments in terms of archiving and curation are then considered. The paper concludes with remarks about social and technological issues posed by Grid–enabled ‘collaboratories’ in both scientific and commercial contexts.
