virtual | ~Random () |
Destroys the random number generator. | |
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.
MersenneRNG::MersenneRNG | ( | unsigned int | seed | ) |
Create a new Mersenne RNG with a specified seed.
[in] | seed | The seed for this RNG |
References seed().
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.
