Performance of UK in the LHCb Service Challenge 3 (ongoing - soon to be finished)
The following paragraph is abstracted from the following webpage at CERN discussing LCG deployment schedule from 2006 to 2008.
Service Challenge 3 operates a reliable base service including most of the Tier-1 centres and some Tier-2s. It has two phases - a setup phase terminating with a throughput test, followed by a three-month period of stable operation during which experiments may carry out tests of their software chains and computing models.
The SC3 is scheduled to end in December 2005. Here, I gather data relating to the performance of UK institutes during this service challenge.
