Function Documentation

◆ hipsparseLtMatmulAlgGetAttribute()

hipsparseStatus_t hipsparseLtMatmulAlgGetAttribute	(	const hipsparseLtHandle_t *	handle,
		const hipsparseLtMatmulAlgSelection_t *	algSelection,
		hipsparseLtMatmulAlgAttribute_t	attribute,
		void *	data,
		size_t	dataSize )

Get the specific algorithm attribute from the algorithm selection descriptor.

hipsparseLtMatmulAlgGetAttribute returns the value of the queried attribute belonging to the algorithm selection descriptor.

Parameters

[in]	handle	the hipsparselt handle.
[in]	algSelection	the algorithm selection descriptor.
[in]	attribute	attributes are specified in hipsparseLtMatmulAlgAttribute_t.
[in,out]	data	the memory address containing the attribute value retrieved by this function.
[in]	dataSize	size in bytes of the attribute value used for verification.

Return values

HIPSPARSE_STATUS_SUCCESS	the operation completed successfully.
HIPSPARSE_STATUS_INVALID_VALUE	handle, algSelection, attribute, data, or dataSize is invalid.
HIPSPARSE_STATUS_NOT_SUPPORTED	attribute is not supported.

◆ hipsparseLtMatmulAlgSelectionDestroy()

hipsparseStatus_t hipsparseLtMatmulAlgSelectionDestroy

(

const hipsparseLtMatmulAlgSelection_t *

algSelection

)

Destroy the algorithm selection descriptor.

hipsparseLtMatmulAlgSelectionDestroy releases the resources used by an instance of the algorithm selection. This function is the last call with a specific algorithm selection instance.

Parameters

[in]

algSelection

the algorithm selection descriptor

Return values

HIPSPARSE_STATUS_SUCCESS	the operation completed successfully.
HIPSPARSE_STATUS_INVALID_VALUE	algSelection is invalid.

◆ hipsparseLtMatmulAlgSelectionInit()

hipsparseStatus_t hipsparseLtMatmulAlgSelectionInit	(	const hipsparseLtHandle_t *	handle,
		hipsparseLtMatmulAlgSelection_t *	algSelection,
		const hipsparseLtMatmulDescriptor_t *	matmulDescr,
		hipsparseLtMatmulAlg_t	alg )

Initializes the algorithm selection descriptor.

hipsparseLtMatmulAlgSelectionInit creates a algorithm selection descriptor.

Parameters

[in]	handle	the hipsparselt handle.
[out]	algSelection	the pointer to the algorithm selection descriptor.
[in]	matmulDescr	the matrix multiplication descriptor.
[in]	alg	the algorithm used to perform the matrix multiplication.

Return values

HIPSPARSE_STATUS_SUCCESS	the operation completed successfully.
HIPSPARSE_STATUS_INVALID_VALUE	handle, matmulDescr, or algSelection is invalid.

◆ hipsparseLtMatmulAlgSetAttribute()

hipsparseStatus_t hipsparseLtMatmulAlgSetAttribute	(	const hipsparseLtHandle_t *	handle,
		hipsparseLtMatmulAlgSelection_t *	algSelection,
		hipsparseLtMatmulAlgAttribute_t	attribute,
		const void *	data,
		size_t	dataSize )

Specify the algorithm attribute of a algorithm selection descriptor.

hipsparseLtMatmulAlgSetAttribute sets the value of the specified attribute belonging to a algorithm selection descriptor.

Parameters

[in]	handle	the hipsparselt handle.
[in,out]	algSelection	the algorithm selection descriptor.
[in]	attribute	attributes are specified in hipsparseLtMatmulAlgAttribute_t.
[in]	data	pointer to the value to which the specified attribute will be set.
[in]	dataSize	size in bytes of the attribute value used for verification.

Return values
