  The most popular and widely used subtract-with-borrow generator, also known
as RANLUX, is reimplemented as a linear congruential generator using large
integer arithmetic with the modulus size of 576 bits. Modern computers, as well
as the specific structure of the modulus inferred from RANLUX, allow for the
development of a fast modular multiplication -- the core of the procedure. This
was previously believed to be slow and have too high cost in terms of computing
resources. Our tests show a significant gain in generation speed which is
comparable with other fast, high quality random number generators. An
additional feature is the fast skipping of generator states leading to a
seeding scheme which guarantees the uniqueness of random number sequences.
