  Speakers: Efe Yazgan (Chinese Academy of Sciences (CN)), Josh McFayden (CERN), Qiang Li (Peking University (CN))
  
  Official Numbers from CMS Computing:
  
  - Gen+Sim = 50 sec/ev/core
  - Digi:             10 sec/ev/ecore
  - Reco:            25 sec/ev/core
  
  Assume 1 core = 10 HS06, note this introduces a 20% error at least.
  
  Table 1, CMS:
  
  Total Events: 1.41+1.96+0.43+1.94+0.712+0.154+0.876+1.95=9.4B
  
  GEN faction: (1.41*0.05+1.96*0.17+0.43*0.05+1.94*0.04+0.712*0.05+0.154*0.05+0.876*0.05+1.95*0.05)/9.4
  ~7.3%
  
  where 0.05, 0.17 and 0.04 are from numbers achieved from local tests, presented in last meetings:
  
  DY LO MLM 5%
  DY NLO 17%
  TT powheg 4%
  QCD 50to80 Pythia8 <1%
  
  Thus GEN -> 85*7.3%=6.2 sec/ev/core
  
           6.2*9.4B=58.3B
