Abstract: A parallel computer system adds entropy to improve the quality of random number generation by using parity errors as a source of entropy because parity errors are influenced by external forces such as cosmic ray bombardment, alpha particle emission, and other random or near-random events. By using parity errors and associated information to generate entropy, the quality of random number generation in a parallel computer system is increased.
