[Gate-users] Number of primaries issue

[Eslam Taha]

Dear Gate users

I am facing an issue whenever I try to simulate more than 2E9 particles.
When I use 2E9 the simulation runs smoothly, but increasing the number of
primaries to 2.1E9 the simulation starts and then ends instantaneously. Any
idea what is causing this problem?
