Random number generator

In 1982, the authors produced a pseudo-random number generator that has been widely used, but now has been shown to be inadequate by today's standards.

In producing a revised generator, extensive use has been made of a test package TestU01 for random number generators. Using this, criteria have been devised for the revised generator - also other high quality generators have been identified.

Facilities have been devised to allow the new generator to be used in a highly parallel environment, which is likely to be a feature of many future applications.
