type Generator 

type Generator struct {
	// contains filtered or unexported fields
}

Generator is a random number generator for the device.

func CreateGenerator 

func CreateGenerator(gentype RngType) *Generator

CreateGenerator creates a Generator

func CreateGeneratorEx 

func CreateGeneratorEx(w *gocu.Worker, gentype RngType) *Generator

CreateGeneratorEx creates a generater where the operations will flow through a worker

func (*Generator) Destroy 

func (c *Generator) Destroy() error

Destroy destroys the random generator. This doesn't do anything right now

func (*Generator) NormalFloat32 

func (c *Generator) NormalFloat32(mem cutil.Mem, sizeinbytes uint, mean, std float32) error

NormalFloat32 -generates a Normal distribution in float32

from cuRAND documentation: The curandGenerateNormal() function is used to generate normally distributed floating point values with the given mean and standard deviation.

func (*Generator) SetPsuedoSeed 

func (c *Generator) SetPsuedoSeed(seed uint64) error

SetPsuedoSeed sets the seed for the curand generator

func (*Generator) SetStream 

func (c *Generator) SetStream(stream gocu.Streamer) error

SetStream sets the a cuda stream for the curand generator

func (*Generator) Uint 

func (c *Generator) Uint(mem cutil.Mem, sizeinbytes uint) error

Uint fills mem with random numbers

From cuRAND documentation: The curandGenerate() function is used to generate pseudo- or quasirandom bits of output for XORWOW, MRG32k3a, MTGP32, MT19937, Philox_4x32_10 and SOBOL32 generators. Each output element is a 32-bit unsigned int where all bits are random. For SOBOL64 generators, each output element is a 64-bit unsigned long long where all bits are random. curandGenerate() returns an error for SOBOL64 generators. Use curandGenerateLongLong() to generate 64 bit integers with the SOBOL64 generators. //values need to be stored as an uint32

func (*Generator) Uint64 

func (c *Generator) Uint64(mem cutil.Mem, sizeinbytes uint) error

Uint64 fills mem with unsigned long long random numbers

From cuRAND documentation: The curandGenerate() function is used to generate pseudo- or quasirandom bits of output for XORWOW, MRG32k3a, MTGP32, MT19937, Philox_4x32_10 and SOBOL32 generators. Each output element is a 32-bit unsigned int where all bits are random. For SOBOL64 generators, each output element is a 64-bit unsigned long long where all bits are random. curandGenerate() returns an error for SOBOL64 generators. Use curandGenerateLongLong() to generate 64 bit integers with the SOBOL64 generators. //values need to be stored as an uint32

func (*Generator) UniformFloat32 

func (c *Generator) UniformFloat32(mem cutil.Mem, sizeinbytes uint) error

UniformFloat32 - generates uniform distributions in float32

from cuRAND documentation: The curandGenerateUniform() function is used to generate uniformly distributed floating point values between 0.0 and 1.0, where 0.0 is excluded and 1.0 is included.
