SetOrgShape

Function Usage

Sets the original complete shape in the M, N, and K directions during Matmul computation. The unit is the number of elements.

Prototype

int32_t SetOrgShape(int32_t orgMIn, int32_t orgNIn, int32_t orgKIn)

int32_t SetOrgShape(int32_t orgMIn, int32_t orgNIn, int32_t orgKaIn, int32_t orgKbIn)

Parameters

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);  // Set the original complete shape.
tiling.SetBias(true);   
tiling.SetBufferSpace(-1, -1, -1);
optiling::TCubeTiling tilingData;   
int ret = tiling.GetTiling(tilingData);
