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
