Nature of problem:
Any calculation requiring uniform pseudorandom number generator, in particular, Monte Carlo calculations. Any calculation or simulation requiring uncorrelated parallel streams of uniform pseudorandom numbers.
The library contains realization of a number of modern and reliable generators: MT19937, MRG32K3A and LFSR113. Also new realizations of the method based on parallel evolution of an ensemble of transformations of two-dimensional torus are included in the library: GM19, GM29, GM31, GM61, GM55, GQ58.1, GQ58.3 and GQ58.4. The library contains: single-threaded and multi-threaded realizations for GPU, single-threaded realizations for CPU, realizations for CPU based on SSE command set. Also, the library contains the abilities to jump ahead inside RNG sequence and to initialize independent random number streams with block splitting method for each of the RNGs.
Nvidia Cuda Tooklit version 5.0 or later should be installed. To use GPU realizations, Nvidia GPU supporting CUDA and the corresponding Nvidia driver should be installed. For SSE realizations of the generators, Intel or AMD CPU supporting SSE2 command set is required. In order to use the SSE realization of LFSR113, CPU must support SSE4 command set.
A "serial" version of this program is held in the Library as Catalogue Id., AEIT_v2_0 (RNGSSELIB). It does not require a GPU device or CUDA compiler.
The tests and the examples included in the package take less or about one minute to run. Running time is analysed in detail in Sec. 8 of the paper.
