I have some additional questions on the same subject.
According to the novice example N03, if I enable saving the random number by calling
inside BeginOfRunAction, the random generator status is saved at the beginning of each run to currentRun.rndm and of each event to currentEvent.rndm.
If I then use the final version of the currentEvent.rndm coming from an old run to initialize the seed of a new run using the
command, the first event of the new run will be identical to the last event of the old run. Is this correct? Is there any way to save to final state of the random engine just before the program exits, so that the new run will be the natural continuation of the old one?
Another question: I would like to run several copies of the same program in parallel. In order to have independent results, I want to initialize the random engine of each copy with a different (independent) seed. I gave a look into a currentEvent.rndm file and it has a format like
Uvec 1878463799 0 1487912126 868880632
What is the meaning of the four numbers and how should I generate them in order to obtain independent seeds?
