GetSingleShape

Function

Obtains the computed singleCoreM, singleCoreN, and singleCoreK.

Prototype

int32_t GetSingleShape(int32_t &shapeM, int32_t &shapeN, int32_t &shapeK)

Parameters

**Table 1** Parameters
Parameter	Input/Output	Description
shapeM	Output	Obtains the singleCoreM value generated by multi-core tiling computation.
shapeN	Output	Obtains the singleCoreN value generated by multi-core tiling computation.
shapeK	Output	Obtains the singleCoreK value generated by multi-core tiling computation.

Returns

-1: setting failed; 0: setting succeeded.

Restrictions

This API needs to be called using the created tiling object after the tiling computation (GetTiling) is complete.

Example

auto ascendcPlatform = platform_ascendc::PlatformAscendC(context->GetPlatformInfo());
matmul_tiling::MultiCoreMatmulTiling tiling(ascendcPlatform); 
tiling.SetDim(1);
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);   
tiling.SetSingleShape(1024, 1024, 1024);
tiling.SetOrgShape(1024, 1024, 1024);
tiling.SetBias(true);   
tiling.SetBufferSpace(-1, -1, -1);
optiling::TCubeTiling tilingData;   
int ret = tiling.GetTiling(tilingData);

// Obtain the computed singleCoreM, singleCoreN, and singleCoreK.
int32_t singleM, singleN, singleK;
int ret1 = tiling.GetSingleShape(singleM, singleN, singleK);
