Concurrency and Computation: Practice and Experience CCLRC Portal Infrastructure to support Research Facilities

The CCLRC e-Science Centre is working on a number of UK e-Research projects supporting access to large research facilities such as the neutron spallation source ISIS, the Synchrotron Radiation Source (SRS) and the Central Laser Facility (CLF) and the new synchroton light source, Diamond, in addition to the National Grid Service and the HPCx supercomputing facility. The aim of this work is to create a

Building the e-science grid in the UK: middleware, applications and tools deployed at level 2

Over the period September 2002-April 2003 the UK Grid Engineering Task Force and staff at Regional e-Science Centres and CCLRC deployed the Globus Toolkit GT2 at 14 sites and on approximately 80 compute resources to set up the first production-quality e-Science Grid for the UK. This work is proving to be exemplary of what can be achieved using heterogeneous resources on a national scale and is feeding discussions on how to link Grids with multiple virtual organisations across Europe. This paper therefore reports on experiences of this deployment exercise, compares with other efforts worldwide and suggests further work to be done
