SetBatchInfoForNormal

Function Usage

In the scenario where the layout mode is NORMAL, before calling IterateBatch or IterateNBatch, call this API to set the M, N, and K axis information of matrix A/B and the number of batches of matrix A/B in the tiling implementation on the host.

Prototype

int32_t SetBatchInfoForNormal(int32_t batchA, int32_t batchB, int32_t m, int32_t n, int32_t k)

Parameters

**Table 1** Parameters
Parameter	Input/Output	Description
batchA	Input	Number of batches of matrix A
batchB	Input	Number of batches of matrix B
m	Input	M-axis information of matrix A
n	Input	N-axis information of matrix A
k	Input	K-axis information of matrix A/B

Returns

-1: setting failed; 0: setting succeeded.

Precautions

None

Example

auto ascendcPlatform = platform_ascendc::PlatformAscendC(context->GetPlatformInfo())
matmul_tiling::MultiCoreMatmulTiling tiling(ascendcPlatform);   
int32_t M = 32;
int32_t N = 256;
int32_t K = 64;
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(M, N, K);
tiling->SetOrgShape(M, N, K);
tiling->SetBias(true);
tiling->SetBufferSpace(-1, -1, -1);

constexpr int32_t BATCH_NUM = 3;
tiling->SetBatchInfoForNormal(BATCH_NUM, BATCH_NUM, M, N, K); //: Set the matrix layout.
tiling->SetBufferSpace(-1, -1, -1);

optiling::TCubeTiling tilingData;
int ret = tiling.GetTiling(tilingData);
