Function Usage

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

Prototype

template <typename T>
__aicore__ inline T GetAccVal()

Parameters

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

Returns

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

Constraints

None

Examples

AscendC::LocalTensor<float> src;
AscendC::LocalTensor<float> work;
AscendC::LocalTensor<float> dst;
AscendC::ReduceSum(dst, src, work, 128);
