GetTiling

Function

Obtains tiling parameters.

Prototype

int64_t GetTiling(optiling::Conv3DBackpropFilterTilingData& tiling)

int64_t GetTiling(AscendC::tiling::Conv3DBackpropFilterTilingData& tiling)

Parameters

**Table 1** Parameters
Parameter	Input/Output	Description
tiling	Output	Tiling structure of TConv3DBpFilterTiling, which is used to store the final Tiling result. For details about the TConv3DBpFilterTiling structure, see TConv3DBpFilterTiling Structure.

Returns

If the return value is not -1, the tiling computation is successful. You can use the value of the tiling structure. If the return value is -1, the tiling computation fails and the tiling result cannot be used.

Restrictions

None

Example

#include "tiling/conv_backprop/conv3d_bp_filter_tiling.h"
