SimpleRandom

object SimpleRandom extends AnyRef

A random number generator that focuses on speed and lack of inter-thread interference, rather than on the quality of the numbers returned. The object SimpleRandom is striped internally to reduce contention when accessed from multiple threads. The class SimpleRandom should only be used by a single thread.

The constants in this 64-bit linear congruential random number generator are from http://nuclear.llnl.gov/CNP/rng/rngman/node4.html.
