Constructor & Destructor Documentation

xorwow_engine()

FQUALIFIERS rocrand_device::xorwow_engine::xorwow_engine ( const unsigned long long  seed, const unsigned long long  subsequence, const unsigned long long  offset  )

inline

Initializes the internal state of the PRNG using seed value seed, goes to subsequence -th subsequence, and skips offset random numbers.

A subsequence is 2^67 numbers long.

Member Function Documentation

discard_subsequence()

FQUALIFIERS void rocrand_device::xorwow_engine::discard_subsequence ( unsigned long long  subsequence )

inline

Advances the internal state to skip subsequence subsequences.

A subsequence is 2^67 numbers long.
