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.
