• 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.
