Following on the recent CRAN release ofrTRNG, it’stime to show its features and usage more in detail. rTRNG isa new package for advanced parallel Random Number Generation in R. It relieson TRNG (Tina’s Random NumberGenerator), a state-of-the-art C++ pseudo-random number generator library forsequential and parallel Monte Carlo simulations. In particular, parallelrandom number generators provided by TRNG can be manipulated by jump andsplit operations. These allow to jump ahead by an arbitrary number of stepsand to split a sequence into any desired sub-sequence(s), thus enablingtechniques such as block-splitting and leapfrogging suitable to parallelalgorithms. Background and Motivation ... Read More
