[Gate-users] Can't run with 100 million particles

Dear Loïc,
I've tried to run my main macro file through the following command: "/control/loop myMain.mac mycounter 1 10 10"which is supposed to run 10 simulations with 10 million particles with different seeds (by /gate/random/setEngineSeed auto). But It runs only the first 10 million particles and doesn't keep run the remains.Do you have any idea what's wrong with this command? I guess it's the only way I can proceed with 100 million primaries without getting error.
Best regardsSoman

My suggestion is therefore to run 10 simulations of 10 million particles (fully equivalent to a single simu of 100 million). You just have to make sure the seeds are different for every simulation, which can be easily achieved using the following command: /gate/random/setEngineSeed auto    Best, Loïc    From: S.

Subject: Re: [Gate-users] Can't run with 100 million particles    Hi,    Thanks a lot for your note. I use of splitting 1000 for my emitted photons but I still have unacceptable uncertainties, so I have to run with 100 million particles. Do you tell me if I run 10 simulations with 10 million particles, it would lessen the uncertainty? I guess it wouldn't, because I have uncertain results with a single simulation of 10 million particles.    Thanks in advance for your help - Soman       On Wednesday, October 1, 2014 3:41 PM, Grevillot Loic <loic.grevillot at medaustron.at> wrote:    Dear Soman,   We noticed a similar simulation “artifact” when a too high number of particles was used. We also noticed that the effect is dependent on the particle type and simulation parameters (cut, step size). We will try correcting the bug for the next release. In the meantime I advise you to run 10 simulations of 10 million particles.   Sincerely,   Loïc       From:gate-users-bounces at lists.opengatecollaboration.org [mailto:gate-users-bounces at lists.opengatecollaboration.org]On Behalf Of S.

Subject: [Gate-users] Can't run with 100 million particles   Hi,   Is there any limitation on the number of primary particles generated in Gate7.0 ? It seems running code with more than 10 million particles leads to false results. I need to run my code with 100 millions particles, but after checking (with a very simple example), I noticed that no more than 20 million particles would be generated.   Thanks for your comments. - Soman Disclaimer:
