GetSwishTmpSize

Function

Obtains Swish tiling parameters, which are, the maximum and minimum temporary space sizes required for Swish computation.

Prototype

inline void GetSwishTmpSize(const ge::Shape& srcShape, const uint32_t typeSize, const bool isReuseSource, uint32_t& maxValue, uint32_t& minValue)

Parameters

**Table 1** API parameters
Parameter	Input/Output	Description
srcShape	Input	Input shape.
typeSize	Input	Size of the input data type, in bytes. For example, if the input data type is half, set this parameter to 2, which means sizeof(half).
isReuseSource	Input	Whether to reuse the space of the source operand input, which must be the same as that of the API in the kernel.
maxValue	Output	Maximum size of the temporary space required by Swish computation. Any space exceeding this value will not be utilized by the API. Within the range between the minimum and maximum, as the temporary space increases, the API computing performance in the kernel can be optimized to some extent. For better performance, reserve or allocate the temporary space based on the actual memory usage. If the maximum space size is 0, no temporary space is required. NOTE: maxValue is for reference only and may be larger than the remaining space of the Unified Buffer. In this case, select a proper temporary space size based on the remaining space of the Unified Buffer.
minValue	Output	Minimum size of the temporary space required by Swish computation. To ensure correct functions, the temporary space to be reserved or allocated during API computation cannot be less than the value of this parameter. If the minimum space size is 0, no temporary space is required.

Returns

None

Restrictions

None

Example

// The input shape is 1024. The operator input data is of the half type. The source operand cannot be modified.
std::vector<int64_t> shape_vec = {1024};
ge::Shape shape(shape_vec);
uint32_t maxValue;
uint32_t minValue;
AscendC::GetSwishTmpSize(shape, 2, false, maxValue, minValue);
