◆ threefry2x64_20_engine()

FQUALIFIERS rocrand_device::threefry2x64_20_engine::threefry2x64_20_engine	(	const unsigned long long	seed = `0`,
		const unsigned long long	subsequence = `0`,
		const unsigned long long	offset = `0`
	)

inline

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

A subsequence consists of 2 ^ 65 random numbers.

FQUALIFIERS void rocrand_device::threefry2x64_20_engine::seed	(	const unsigned long long	seed = `0`,
		const unsigned long long	subsequence = `0`,
		const unsigned long long	offset = `0`
	)

inline

Reinitializes the internal state of the PRNG using new seed value seed_value, skips subsequence subsequences and offset random numbers.

A subsequence consists of 2 ^ 65 random numbers.
