[Gate-users] maximum running time

[Eric Vandervoort]

Hello,
I got around this by just running shorter simulations. My guess is that
the number of decays is defined as data type G4int (defined somewhere in
the geant4 code). Maybe the sizeof(G4int) is independent of the operating
system. Does anyone know this for sure?
Best Regards,
Eric
