Photos of the CERN Computer Centre
Friday, November 14th, 200850,000 processor cores and counting.. about half of these cores will be used to deal with data from the LHC which will generate about 15 petabytes of data by colliding protons with protons. The Computer Centre will provide only about 20 percent of the processing power used to examine the LHC data, with the rest coming from the LHC Computing Grid, a dedicated network of more than 100,000 processors. The grid is linked to the centre through dedicated 10-gigabit-per-second connections. It can handle about 50,000 users at once, sharing out bandwidth and processing power between scientists. To store the huge amount of data the LHC produces, the centre owns 8 petabytes of hard disks and 18 petabytes of magnetic tapes. This will increase to 16 petabytes of hard disks and 30 petabytes of tapes by the end of the year. Check out the photos, enjoy!
