Question /random/setSeeds question 

Forum: Run Management
Date: 11 Jul, 2014
From: Stefan E. Mueller <Stefan E. Mueller>


maybe I misinterpreted the answers to a previous post of mine. I am trying to initialize the random number generator in Geant4 such that I can launch several jobs (or several runs) without simply reproducing the results.

I therefore submitted a job with a .mac-file with the line

/random/setSeeds 575841909 838392975

and another one with the line

/random/setSeeds 770353837 70597151

Contrary to what I expected, the output of the two runs is identical.

Apparently there is something I missed. However, in I see that the seeds array is passed on to


So why are my two runs identical?
