RngStreams is an object-oriented random-number package with many long streams and substreams, based on the MRG32k3a RNG from reference [1] below and proposed in [2]. It has implementations in C, C++, Java, R, OpenCL, and some other languages. The main description and documentation is in the c++ directory, in the paper streams.pdf. Directories c and java gives a short description of the interfaces in C and Java, respectively. The package is copyrighted by Pierre L'Ecuyer and the University of Montreal. It can be used freely for any purpose. e-mail: lecuyer@iro.umontreal.ca http://www.iro.umontreal.ca/~lecuyer/ If you use it for your research, please cite the following relevant publications in which MRG32k3a and the package with multiple streams were proposed: [1] P.
