RE: [EnergyPlus_Support] Re: How to properly set the random seed for stochastic processes in EMS?





Ah that is difficult to answer definitively, but I would not make that assumption.  EMS is using Fortran intrinsics here and the implementation is actually in the CPU hardware.  So different computer chips will behave differently.  I agree with your reasoning but if you were getting sufficiently random sequences in V7.2, then it may be that integers 1,2,3,… will suffice in V8.0.  

 

If I can ask another question, would I be limiting the random number generator if I just used the integers 1,2,3,...,1000 as seeds? would this lead to somehow similar, or ordered sequences of random numbers? My assumption is yes, which is why i want to use seeds distributed across the entire range of possible integers.

Thanks again,
Ryan
