A new class of random number generators required for advanced computer architectures

This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The advent of ever more powerful computers allows one to run Monte Carlo computations of unprecedented length. Currently used random number generators (RNGs) do not have the cycle length necessary for these computations. It is possible to cycle completely through most RNGs used on workstations in a few minutes computations. Even having a long period may not qualify a RNG as suitable. The authors are developing tests that will allow them to develop high quality RNGs for use in long computations
