• Description: Computes the product of matrix input and vector vec.

• Formula:

  $$out = input * vec$$

  $input$ is a two-dimensional tensor of n x m, $vec$ is a one-dimensional tensor of length m, and $out$ is a one-dimensional tensor of length n.

• Example:

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

• Input parameters:

  [object Object]
  • [object Object]Atlas training series products[object Object] and [object Object]Atlas inference series products[object Object]:
  • The data type BFLOAT16 is not supported.
  • cubeMathType=0 is not supported when the input data type is FLOAT32.
  • cubeMathType=1: If the input data type is FLOAT32, it is converted to FLOAT16 for computation. If the input data type is not FLOAT32, no processing is performed.
  • cubeMathType=3 is not supported.
  • [object Object]Atlas A2 training products/Atlas A2 inference products[object Object] and [object Object]Atlas A3 training series products/Atlas A3 inference series products[object Object]:
    • cubeMathType=1: If the input data type is FLOAT32, it is converted to HFLOAT32 for computation. If the input data type is not FLOAT32, no processing is performed.
    • cubeMathType=2: If the input data type is BFLOAT16, this option is not supported.
    • cubeMathType=3: If the input data type is FLOAT32, it is converted to HFLOAT32 for computation. If the input data type is not FLOAT32, this option is not supported.

• Returns:

  aclnnStatus: status code. For details, see .

• Deterministic description:
  • [object Object]Atlas training series products[object Object] and [object Object]Atlas inference series products[object Object]: aclnnMv defaults to a non-deterministic implementation. You can call aclrtCtxSetSysParamOpt to enable deterministic compute.
