[Gate-users] Problem with 10^10 primaries send

[Sarah Blind]

Dear Dimitris Thanasas, 

I come back to you about launching GATE with more than 10^9 primaries. 
I have tried to set an activity to my source and to run the simulation for a certain time as you suggested. 
It allowed me to launch my simulation with 10^10 photons, but not more. 

Now I want to split my simulation, but I don't now how exactly and I can't find any information about it, would you give me some advices ? 

Thank you very much for your help, 
Regards, 
Sarah Blind
