[Gretl-users] Re: random numbers in MPI

Hi, here's a question about some details of random number generation in MPI-parallelized scripts. I have read the relevant section 7 of the gretl + MPI guide, but one thing still isn't clear to me: How to imitate the effect of what "set seed" would do in the standard single-thread setting? As far as I understand, the default setting in gretl's MPI world is to have separate RNGs, to preserve independence of the pseudo-random numbers. OK. The alternative that is described in the guide is to enforce identical RNG sequences in all parallel threads. What about the case where you want to have independent RNG sequences across processes, but you want to be able to control them for replication purposes, from one run to the next? How to achieve that effect in gretl's MPI implementation?
