Generate a set of random x,y,z numbers, with a minimum difference between them, between defined limits
So I am trying a molecular dynamics simulation, and trying to populate a 3D rectangular volume with random particles which are uniformly distributed throughout the volume. Each molecule has a fixed ...

Parallel Mersenne Twister for Monte Carlo
Recently, I came across a comment claiming that almost all researchers doing Monte Carlo methods are doing it wrong. It went on to elaborate that merely choosing different seeds for different ...

Multiple independent random number streams
Having multiple streams of pseudo-random numbers known to be independent and with a uniform distribution I want to do Monte Carlo simulations in parallel.
In other words, one thread will have a full-...

How can I seed a parallel linear congruential pseudo-random number generator for maximal period?
Normally when I seed a sequential random number generator in C, I use the call
srand(time(NULL))
then use
rand() mod N
...
