RANLUX - A FORTRAN IMPLEMENTATION OF THE HIGH-QUALITY PSEUDORANDOM NUMBER GENERATOR OF LUSCHER

Following some remarks on the quality of pseudorandom number generator s commonly used in Monte Carlo calculations in computational physics, we offer a portable Fortran 77 implementation of a high-quality genera tor called RANLUX (for LUXury RANdom numbers), using the algorithm of Martin Luscher described in an accompanying article. The implementatio n allows the user to select different quality or luxury levels, where higher quality requires somewhat longer computing time for the generat ion. There is a convenient way of initialization (appropriate also for massively parallel Monte Carlo computations) as well as two different methods of restarting from a break point.
