PoissonDistribution(Double)

Creates a new poisson distribution.

Construct histogram array for poisson distribution.

Construct histogram array for poisson distribution with lambda lambda. For lambda greater than 2000 optimization with normal distribution is used.

Generate(CudaRandDevice, CudaDeviceVariable<UInt32>)

Generate Poisson-distributed unsigned ints.

Use generator to generate num unsigned int results into the device memory at outputPtr. The device memory must have been previously allocated and be large enough to hold all the results. Launches are done with the stream set using curandSetStream(), or the null stream if no stream has been set. Results are 32-bit unsigned int point values with poisson distribution based on an associated poisson distribution with lambda lambda.

Declaration
public void Generate(CudaRandDevice generator, CudaDeviceVariable<uint> output)
Parameters
Type Name Description
CudaRandDevice generator

Generator to use
CudaDeviceVariable<System.UInt32> output

Pointer to device memory to store CUDA-generated results

Generate(CudaRandHost, UInt32[])

Generate Poisson-distributed unsigned ints.

Use generator to generate num unsigned int results into the device memory at outputPtr. The device memory must have been previously allocated and be large enough to hold all the results. Launches are done with the stream set using curandSetStream(), or the null stream if no stream has been set. Results are 32-bit unsigned int point values with poisson distribution based on an associated poisson distribution with lambda lambda.

Declaration
public void Generate(CudaRandHost generator, uint[] output)
Parameters
Type Name Description
CudaRandHost generator

Generator to use
System.UInt32[] output

Pointer to host memory to store CPU-generated results
