Abstract
Denne artikel beskriver LHC-grid’ets arkitektur med Tier-0, Tier-1 og Tier-2 centre. Datamængder på petabyte-skala og dedikerede 10 Gbit-forbindelser illustrerer infrastrukturen. Reprocessering, simulering og forskeradgang organiseres globalt. Artiklen viser, hvordan distribueret computing er en forudsætning for moderne højenergifysik. For fysikere med interesse i e-science er dette et konkret eksempel på big data før begrebet blev mainstream.
