typedef G4RunManager RunManager

ts_scorers example shows how to use global scorers. The benefit of using global scorers in memory-savings for problems with very large amounts of scoring volumes. Additionally, the global scorers are more precise w.r.t. the serial solution because of the lack of compounding round-off error from multiple threads

In this example, the global scorers are implemented as static member variables in TSRun because TSRun is thread-local. The G4atomic class is the core of the thread-safe scorers and can be uses
