[Help-gsl] How many RNG instances?

[Joe]

Hi Everybody,

I have a simple question. Do I need a seperate random number generator
instance for each distribution I use? E.g, I have two different simulation
parameters, one exponential, the other poisson distributed.

Basically, right now, my RNG is wrapped within a singleton class meaning
that I have only one instance, systemwide. Is this a good approach?

Thanks,
Joe
