This paper describes an implementation of a Linear Congruential Generator (LCG) based on the binary representation of the normal number α 2 , 3 , and of a combined generator based on that LCG. The base LCG with the modulus 3 33 provides a quality sequence with the period ≈3.7⋅10 15 , which passes all but two statistical tests from BigCrush test suite. We improved on the original implementation by adapting Barrett’s modular reduction method, which resulted in four-fold increase in efficiency. The combined generator has the period of ≈10 23 and passes all tests from BigCrush suite.

Nature of problem: This is a fast pseudorandom number generator based on normal numbers, with long period and good statistical properties. It passes all 106 BigCrush statistical tests and is faster than C standard library rand generator. Suitable for parallel execution by multiple threads and/or processes because of skip ahead property. Solution method: Linear Congruential Generators with specially chosen parameters are used. A customized fast modular reduction is employed. Running time: Generation rate is 100–200 million numbers per second.
