Next events in a run with the same seed offset

Asked by Zachary Marshall

Hi there,

I want to generate consecutive sets of events with the same random number seed. That is, I want to generate N events, and then come along at a later time and generate another N events starting from the same random state that I finished the first generation with. Is that possible with MG5?

Thanks,
Zach

Thanks Olivier. Any chance to make it possible?

In case not, what is the limit for the random number seed?

Thanks,
Zach

Not really,.

I do not know the exact number but this is for sure bigger than 30,000**2=900,000,000

Cheers,
