I'm just beginning to learn about random engine and I have two questions. I'm running AnaEx01. I saw the line 67 of AnaEx01.cc:
but i did not see where is it called in other cc files. If I comment out this line the program gives the same result, seems like it runs just fine without it.
My first question is: Is the random engine being called in AnaEx01?
The other place where I notice randomization is used is in GeneratePrimaries() in AnaEx01PrimaryGeneratorAction.cc, I guess maybe random engine is used here. I change rndmFlag("off") to rndmFlag("on"), then recompile everything. The results for mean and rms is different this time, but if I rerun it will give identical results again.
My second question is: If I turn on rndmFlags, Should the program behave like this, where results will be different upon first compilation but identical results after that in every run?
