Function Usage

Obtains the computation result of the ReduceSum API (API for computing the first n data elements of a tensor, where n is the count parameter passed to the API).

Prototype

template <typename T>
__aicore__ inline T GetReduceRepeatSumSpr()

Parameters

**Table 1** Parameters in the template
Parameter	Description
T	Data type of the ReduceSum instruction. The value can be half or float.

Returns

Computation result of the ReduceSum API (API for computing the first n data elements of a tensor, where n is the count parameter passed to the API).

Restrictions

None

Examples

AscendC::LocalTensor<float> src;
AscendC::LocalTensor<float> work;
AscendC::LocalTensor<float> dst;
AscendC::ReduceSum(dst, src, work, 128);
float res = AscendC::GetReduceRepeatSumSpr<float>(); // Return the sum of the first 128 numbers.
