This paper previews the imminent flood of scientific data expected from the next generation of experiments, simulations, sensors and satellites. In order to be exploited by search engines and data mining software tools, such experimental data needs to be annotated with relevant metadata giving information as to provenance, content, conditions and so on. The(More)
After some remarks on the fundamental physical nature of information, Bennett and Fredkin's ideas of reversible computation are introduced. This leads on to the suggestions of Benioff and Feynman as to the possibility of a new type of essentially 'quantum computers'. If we can build such devices, Deutsch showed that 'quantum parallelism' leads to new(More)
1.1 THE GRID The Grid is the computing and data management infrastructure that will provide the electronic underpinning for a global society in business, government, research, science and entertainment [1–5]. Grids, illustrated in Figure 1.1, integrate networking, communication , computation and information to provide a virtual platform for computation and(More)
Here we describe the requirements of an e-Infrastructure to enable faster, better, and different scientific research capabilities. We use two application exemplars taken from the United Kingdom's e-Science Programme to illustrate these requirements and make the case for a service-oriented infrastructure. We provide a brief overview of the UK "plug-and-play(More)
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(More)
This presentation will set out the eScience agenda by explaining the current scientific data deluge and the case for a " Fourth Paradigm " for scientific exploration. Examples of data intensive science will be used to illustrate the explosion of data and the associated new challenges for data capture, curation, analysis, and sharing. The role of cloud(More)
Recent Grid projects, such as the Globus Project, provide a set of useful services such as authentication and remote access to resources, and information services to discover and query such remote resources. Unfortunately, these services may not be compatible with the commodity technologies used for application development by the software engineers and(More)
The UK e-Science Programme is a £250M, 5 year initiative which has funded over 100 projects. These application-led projects are underpinned by an emerging set of core middleware services that allow the coordinated, collaborative use of distributed resources. This set of middleware services runs on top of the research network and beneath the applications we(More)
This paper describes our experience with some of the prototype HPF parallelisation tools, namely Adaptor, Fortran 90D and xHPF90, as they were available to us at the end of 1993. The comparison and evaluation of these early HPF compilers was equally difficult and important in order to gain some feedback to the compiler designers but also to accumulate some(More)
