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.
