LHC Computing LHC Data per experiment: • 40 million collisions per second • After filtering, 100 collisions of interest per second • A Megabyte of digitised information for each collision = recording rate of 100 Megabytes/sec • 1 billion collisions recorded = 1 Petabyte/year With four experiments, processed data we will accumulate 15 Peta. Bytes of new data each year = 1% of Korean Group is working on CMS LHCb ATLAS 1 Megabyte (1 MB) A digital photo 1 Gigabyte (1 GB) = 1000 MB A DVD movie 1 Terabyte (1 TB) = 1000 GB World annual book production 1 Petabyte (1 PB) = 1000 TB 10% of the annual production by LHC experiments 1 Exabyte (1 EB) = 1000 PB World annual information production ALICE 3 Ref.
