GetBaseN

Function

Obtains the baseN value generated by the tiling computation. For details about the baseN parameter, see Table 1.

Prototype

int32_t GetBaseN() const

Parameters

None

Returns

The return value is the baseN value generated by the tiling computation.

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::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);   
tiling.SetOrgShape(1024, 1024, 1024);  
tiling.SetBias(true);   
tiling.SetBufferSpace(-1, -1, -1);

optiling::TCubeTiling tilingData;   
int ret = tiling.GetTiling(tilingData);
int baseN = tiling.GetBaseN();  // Obtain baseN generated by the tiling computation.
