Year 2018 Expectations HL-LHC aims HL-LHC may deliver up to 2 . 5 × 10 35 cm − 2 s − 1 up to ∼ 350 pileup events HLT farms need to grow proportionally In terms of current processing power, guestimated farm sizes LHCb ∼ 300 k cores ATLAS ∼ 160 k cores CMS ∼ 64 k cores ALICE ∼ 250 k cores and ∼ 6 . 4 k GPUs Memory requirements will also increase due to larger events! Luminosity leveling might change farm size requirements. Sami Kama (Southern Methodist University) HLT Revolutions: LS2 and Beyond DAQ@LHC WS, March 2013 2 / 20
