  7. http://ppewww.ph.gla.ac.uk/ScotGRID/ • SHEFC -JREI funded project Glasgow Physics, Glasgow Computing Science, Edinburgh Physics, Edinburgh Parallel Computing Centre and IBM • ScotGRID is a £800k prototype two-site Tier 2 centre in Scotland for the analysis of data from the Large Hadron Collider and elsewhere. The centre consists of a 128CPU Monte Carlo production facility run by the Glasgow PPE group and a 5TB datastore and associate high-performance server run by Edinburgh Parallel Computing Centre.
