[Gate-users] Help : NumberOfPrimaries

[Gunjan Kayal]

Hi Ibrahim

The maximum number of primaries you can have is 2^(32-1) because Gate deals with 32-bit variable range (~2.1 billion).
In case you want to run higher number of primaries, you can split your simulations and then merge them later on.
I guess there are some available tools (in GateContrib/GateTools) to do the splitting and merging.

Hope this helps.

Regards.
Gunjan
