Resources

Resources

  • Lidia estimated:

  • - pp 500 GeV, pythia with year 2009 geometry - 2.3M events;   we don't have any example for pp 500GeV but we can suppose   that resources will be doubled, in this case it requires:

  • fzd = 600GB;

  • reco = 1.2TB;

  • CPU ~ 18000 hours for reco + ~50% for simu;

  • total CPU ~ 27000 hours(3.2 years);

  • total size ~ 1.8TB;
