• Function: performs the quantized group matrix computation, and then sums up the matrix computation results of all groups and outputs the result.

• Formula:

$$out = \sum_{i=0}^{batch}(x1_i @ x2_i) * x1Scale * x2Scale$$ [object Object]

Each operator has calls. First, aclnnQuantMatmulReduceSumWeightNzGetWorkspaceSize is called to obtain the workspace size required for computation and the executor that contains the operator computation process. Then, aclnnQuantMatmulReduceSumWeightNz is called to perform computation.

• Deterministic description:
  • The aclnnQuantMatmulReduceSumWeightNz API is implemented in non-deterministic mode by default. You can enable deterministic mode by using aclrtCtxSetSysParamOpt.
