Detailed Description

1D CUDA kernel grid configuration.

Grid1D simplifies configuration for 1D kernels by automatically calculating the number of blocks needed to cover n elements with the specified block size.

Constructor & Destructor Documentation

Grid1D() [1/2]

culite::Grid1D::Grid1D

(

)

Default constructor.

Creates a Grid1D with default-initialized dimensions.

Grid1D() [2/2]

culite::Grid1D::Grid1D	(	std::size_t	n,
		std::size_t	blockSize = 256 )

Constructs a 1D grid configuration.

Automatically calculates the number of blocks needed to cover n elements with the given block size. Performs overflow and validation checks.

Parameters

n	Total number of elements to process.
blockSize	Number of threads per block (default: 256).

Exceptions

err::CudaException

if blockSize is zero, if arithmetic overflow occurs, or if calculated values exceed unsigned int maximum.
