r123::Threefry2x64_R Class Reference

#include <Random123/threefry.h>

Detailed Description

exports the member functions, typedefs and operator overloads required by a CBRNG class.

The template argument, ROUNDS, is the number of times the Threefry round function will be applied.

In November 2011, the authors discovered that 13 rounds of Threefry2x64 sequenced by strided, interleaved key and counter increments failed a very long (longer than the default BigCrush length) WeightDistrub test. At the same time, it was confirmed that 14 rounds passes much longer tests (up to 5x10^12 samples) of a similar nature. The authors know of no statistical flaws with ROUNDS=14 or more for Threefry2x64.

The documentation for this class was generated from the following file:
