Summary
Pseudorandom number generation algorithms are key components in many of modern scientific computing applications and the quality of the obtained research results may depend on their characteristics. The random number generating algorithms should be of sufficient quality, so as to allow research to be focused on the scientific problem itself, and not to require detailed study of the behaviour of the generator. SPRNG (Scalable Parallel Random Number Generators) is one of the best libraries for generating pseudorandom numbers for parallel applications. It provides user-friendly interfaces for parallel C/C++ and Fortran applications, which enable the user to easily obtain multiple and sufficiently uncorrelated pseudorandom number streams on different processors, with no inter-process communication. The algorithms implemented in SPRNG are: Combined Multiple Recursive Generator, the 48 bit Linear Congruential Generator, the 64 bit Linear Congruential Generator, the modified Lagged Fibonacci Generator, the multiplicative Lagged Fibbonacci Generator, and the Prime Modulus Linear Congruential Generator.
