Constructor & Destructor Documentation

◆ RNG() [1/2]

quda::RNG::RNG	(	const LatticeField &	meta,
		unsigned long long	seedin
	)

allocate curand rng states array in device memory

Constructor that takes its metadata from a field

Parameters

[in]	meta	The field whose data we use
[in]	seed	Seed to initialize the RNG

◆ RNG() [2/2]

quda::RNG::RNG	(	const LatticeFieldParam &	param,
		unsigned long long	seedin
	)

Constructor that takes its metadata from a param.

Parameters

[in]	param	The param whose data we use
[in]	seed	Seed to initialize the RNG
