[Gate-users] Simulation timing out

[Konstantinos P. Chatzipapas, MSc]

Hello Tyrone,
A solution to your problem may probably be to run 10 different simulations of 10^9 and then sum your outcomes (e.g. sum images). Finally, you will have the result of a simulation with 10^10 histories.

Regards,Konstantinos

 Dear Tyrone Te Ruruku,
I have never seen that number before, it may be that you hit the memory limit of your computer and it stops.
On another note, the number 10^10 of primaries you are trying to simulate will not work because of a Geant4/GATE limitation due to the coding of that integer number in signed 32 bits. The maximum number you can set is 2^32/2 = 2147483648 primaries.
Good luck with your simulations,  Maxime Chauvin

Every time I run my mac file the simulation stops before executing all the primaries. I have stated in my mac file to run 10000000000 but it always stops at 1410065408. Does anyone know why this is might be happening?
