GetTiling

Function

Obtains the Mc2InitTiling and Mc2CcTiling parameters.

Prototype

uint32_t GetTiling(::Mc2InitTiling &tiling)

uint32_t GetTiling(::Mc2CcTiling &tiling)

Parameters

**Table 1** Parameters
Parameter	Input/Output	Description
tiling	Output	Tiling information stored in the tiling structure.

Returns

If the return value is 0, the tiling computation is successful. The value of the tiling structure can be used for subsequent computation.
If the return value is not 0, the tiling computation fails and the tiling result cannot be used.

Restrictions

None

Example

const char *groupName = "testGroup";
uint32_t opType = HCCL_CMD_REDUCE_SCATTER;
std::string algConfig = "ReduceScatter=level0:fullmesh";
uint32_t reduceType = HCCL_REDUCE_SUM;
AscendC::Mc2CcTilingConfig mc2CcTilingConfig(groupName, opType, algConfig, reduceType);
mc2CcTilingConfig.GetTiling(tiling->mc2InitTiling); // tiling is the TilingData structure assembled by the operator. Obtain Mc2InitTiling.
mc2CcTilingConfig.GetTiling(tiling->reduceScatterTiling); // tiling is the TilingData structure assembled by the operator. Obtain Mc2CcTiling.
