[object Object]

[object Object][object Object]undefined[object Object]

• Description: Implements grouped matrix multiplication, supporting non-uniform matrix dimension sizes across multiple groups. The basic function is matrix multiplication, for example, $y_i[m_i,n_i]=x_i[m_i,k_i] \times weight_i[k_i,n_i]+y_i[m_i,n_i], i=1...g$, where $g$ indicates the number of groups and $m_i$, $k_i$, and $n_i$ define the shapes for each group. The input and output data types are both aclTensor, with K-axis grouping.

  • K-axis grouping: $k_i$ can vary, while $m_i$ and $n_i$ remain the same for each group.

• Formula:

  $$yRef_i=x_i\times weight_i + y_i$$

Each operator has calls. First, [object Object] is called to obtain the input parameters and compute the required workspace size based on the process. Then, [object Object] is called to perform computation.

• [object Object] defaults to a deterministic implementation.
• The size of each dimension for every tensor in [object Object] and [object Object], after 32-byte alignment, should be less than the maximum value of INT32 (2147483647).
