SetShape

Function Usage

Sets the shape of a single Matmul computation in the singleM, singleN, and singleK directions. The unit is the number of elements.

Prototype

int32_t SetShape(int32_t singleM, int32_t singleN, int32_t singleK)

Parameters

**Table 1** Parameters
Parameter	Input/Output	Description
singleM	Input	Size of singleM for a single computation. Unit: element.
singleN	Input	Size of singleN for a single computation. Unit: element.
singleK	Input	Size of singleK for a single computation. Unit: element.

Returns

-1: setting failed; 0: setting succeeded.

Precautions

None

Example

auto ascendcPlatform = platform_ascendc::PlatformAscendC(context->GetPlatformInfo());
matmul_tiling::MatmulApiTiling tiling(ascendcPlatform); 
tiling.SetAType(matmul_tiling::TPosition::GM, matmul_tiling::CubeFormat::ND, matmul_tiling::DataType::DT_FLOAT16); 
tiling.SetBType(matmul_tiling::TPosition::GM, matmul_tiling::CubeFormat::ND, matmul_tiling::DataType::DT_FLOAT16);  
tiling.SetCType(matmul_tiling::TPosition::GM, matmul_tiling::CubeFormat::ND, matmul_tiling::DataType::DT_FLOAT);
tiling.SetBiasType(matmul_tiling::TPosition::GM, matmul_tiling::CubeFormat::ND, matmul_tiling::DataType::DT_FLOAT);   
tiling.SetShape(1024, 1024, 1024);  // Set the shape of a single computation.
tiling.SetOrgShape(1024, 1024, 1024);   
tiling.SetBias(true);   
tiling.SetBufferSpace(-1, -1, -1);
