Running on single thread with multi-threading G4

Dear Geant4 gurus,

I am using a LCG-centrally-compiled version of G4 on lxplus, which is multi-threading.
I would like to force it to use one single thread, is there a way to do it?


In your main, instantiate G4RunManager instead of G4MTRunManager. Then it runs in sequential mode.

thank you very much!
