| Abstract: | Quantum Chromodynamics (QCD) is an application area that requires access to large supercomputing resources and generates large amounts of raw data. The UK's national lattice QCD collaboration UKQCD currently stores and requires access to around five Tbytes of data, a figure that is growing dramatically as the collaboration's purpose built supercomputing system, QCDOC P.A.

This data is stored on QCDgrid, a data Grid currently composed of seven storage elements at five separate UK sites. |
