SetSparse

Function

Sets whether the Matmul scenario is the sparse Matmul scenario.

Prototype

      
           int32_t SetSparse(bool isSparseIn = false)

Parameters

**Table 1** Parameters
Parameter	Input/Output	Description
isSparseIn	Input	Sets whether the scenario is a sparse Matmul scenario. true: sparse scenario false: non-sparse scenario

Returns

-1: setting failed; 0: setting succeeded.

Restrictions

This API must be called before the GetTiling API.

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.SetSparse(true); // Set the sparse Matmul scenario.
tiling.SetShape(1024, 1024, 1024);   
tiling.SetOrgShape(1024, 1024, 1024);   
tiling.SetBias(true);   
tiling.SetBufferSpace(-1, -1, -1);
