I have millions of photons saved in a text file. In my primary generator action class in GeneratePrimaries I read one photon at a time, and then give position, direction and energy like this and then generate primary vertex:
fParticleGun->SetParticlePosition(position); fParticleGun->SetParticleMomentumDirection(direction); fParticleGun->SetParticleEnergy(en*MeV);
However, when I loop this millions of times, too much memory is used. The line that uses too much memory is "fParticleGun->GeneratePrimaryVertex(anEvent);".
How can I create a different primary vertex for every particle without using so much memory? I would like to shoot particles once in a while to free memory but I don't see how I could do that since BeamOn() is run somewhere else.
