Description
Using the run card from V_plus_Jets/LHC_ZJets with OpenLoops at LOOPGEN already the lowest multi process doesn't converge
Process_Group::CalculateTotalXSec(): Calculate xs for '2_2jjllQCD(BVI)' (Amegic) Starting the calculation at 22:16:46. Lean back and enjoy ... . 1.61551e+06 pb +- ( 1.55753e+06 pb = 96.4112 % ) 5000 ( 7600 -> 65.7 % ) full optimization: ( 3m 40s elapsed / 3h 55m 32s left ) [22:20:27] 1.12843e+06 pb +- ( 939054 pb = 83.218 % ) 10000 ( 12746 -> 97.1 % ) full optimization: ( 7m 22s elapsed / 3h 52m 19s left ) [22:24:09] 2.5422e+06 pb +- ( 1.72993e+06 pb = 68.0484 % ) 15000 ( 17754 -> 99.8 % )
Is this reproducible by anyone else might there be some latest setting/switch missing?
