Two high-performance Pentium computers, together with associated maintenance, are requested as desktop machines for the RAs. In addition, we request a well-resourced server to use as a Grid service portal. For reasons of security and performance this machine must be divorced from the existing School infrastructure; it is not possible to host this service on our current Web server. Two project laptops will be shared among the project investigators, the RAs and the PhD students. We also request a contribution towards providing a suitable research environment including state-of-the-art networking and Grid computing support. Computing consumables for both the research staff and the investigators' work on the project are also requested. Basic computing equipment to support the investigators themselves is not requested; this is already provided by the School of Informatics.
