Detailed Description

Implements a Mersenne-based RNG for use in the SST core or components.

The Mersenne RNG provides a better "randomness" to the distribution of outputs but is computationally more expensive than the Marsaglia RNG.

Constructor & Destructor Documentation

MersenneRNG::MersenneRNG ( unsigned int seed )

Create a new Mersenne RNG with a specified seed.

Parameters

[in] seed The seed for this RNG

MersenneRNG::MersenneRNG ( )

Creates a new Mersenne using a random seed which is obtained from the system clock.

Note this will give different results on different platforms and between runs.
