Message-ID: <lfqg56$v7b$1@speranza.aioe.org> (raw)
Seen on a recent FAQ:
>Q: Why do all workers in my distributed MATLAB jobs (e.g. Monte Carlo
>simulations) use the same sequence of random numbers?
>
>A: By default MATLAB initializes its random number generator at startup
>based on the system time. Since all nodes in the cluster have
>synchronized clocks, if your job starts up simultaneously on multiple
>nodes those jobs will proceed through the same sequence of random numbers.
