boost::random::xoshiro256mm
// In header: <boost/random/xoshiro.hpp> class xoshiro256mm { public: // public member functions result_type next() noexcept; };
This is xoshiro256** 1.0, one of our all-purpose, rock-solid generators. It has excellent (sub-ns) speed, a state (256 bits) that is large enough for any parallel application, and it passes all tests we are aware of.
For generating just floating-point numbers, xoshiro256+ is even faster.
