Function Description

  • Description: Computes the bitwise OR between elements in the input tensor self and the input scalar other. The input self and other must be of the INT or BOOL type. For the BOOL type, the operator computes the logical OR.
  • Formula:outi=selfi ∣ other\text{out}_i = \text{self}_i \, | \, \text{other}

Prototype

  • aclnnBitwiseOrScalar and aclnnInplaceBitwiseOrScalar implement the same function in different ways. Select a proper operator based on your requirements.

    • aclnnBitwiseOrScalar: An output tensor object needs to be created to store the computation result.
    • aclnnInplaceBitwiseOrScalar: No output tensor object needs to be created, and the computation result is written in place to the input tensor's memory.

  • Each operator has two-phase API calls. First, aclnnBitwiseOrScalarGetWorkspaceSize or aclnnInplaceBitwiseOrScalarGetWorkspaceSize is called to obtain the workspace size required for computation and the executor covering the operator computation process. Then, aclnnBitwiseOrScalar or aclnnInplaceBitwiseOrScalar is called to perform computation.

    • aclnnStatus aclnnBitwiseOrScalarGetWorkspaceSize(const aclTensor *self, const aclScalar *other, aclTensor *out, uint64_t *workspaceSize, aclOpExecutor **executor)
    • aclnnStatus aclnnBitwiseOrScalar(void *workspace, uint64_t workspaceSize, aclOpExecutor *executor, aclrtStream stream)
    • aclnnStatus aclnnInplaceBitwiseOrScalarGetWorkspaceSize(aclTensor *selfRef, const aclScalar *other, uint64_t *workspaceSize, aclOpExecutor **executor)
    • aclnnStatus aclnnInplaceBitwiseOrScalar(void *workspace, uint64_t workspaceSize, aclOpExecutor *executor, aclrtStream stream)

aclnnBitwiseOrScalarGetWorkspaceSize

  • Parameters:

    • self (aclTensor*, computation input): input self in the formula, which is an aclTensor on the device. It supports non-contiguous tensors. Its data format can be ND, and the data dimensions cannot exceed 8.
      • Atlas training products, Atlas inference products, Atlas A2 training products/Atlas A2 inference products, and Atlas A3 training products/Atlas A3 inference products: The data type can be BOOL, INT8, INT16, UINT16, INT32, INT64, or UINT8. The data type must follow the type promotion rules with other (see Type Promotion Rules). The resulting data type must be within the supported range listed above.
    • other (aclScalar*, computation input): input other in the formula, which is an aclScalar on the host.
      • Atlas training products, Atlas inference products, Atlas A2 training products/Atlas A2 inference products, and Atlas A3 training products/Atlas A3 inference products: The data type can be BOOL, INT8, INT16, UINT16, INT32, INT64, or UINT8. The data type must follow the type promotion rules with self (see Type Promotion Rules), and the promoted data type must be within the supported data types.
    • out (aclTensor *, computation output): out in the formula, which is an aclTensor on the device. Its data type must be one convertible from the type deduced from self and other. The shape of out must be the same as that of self. It supports non-contiguous tensors. Its data format can be ND, and the data dimensions cannot exceed 8.
      • Atlas training products and Atlas inference products: The data type can be BOOL, INT8, INT16, UINT16, INT32, INT64, UINT8, FLOAT, FLOAT16, or DOUBLE.
      • Atlas A2 training products/Atlas A2 inference products and Atlas A3 training products/Atlas A3 inference products: The data type can be BOOL, INT8, INT16, UINT16, INT32, INT64, UINT8, FLOAT, FLOAT16, DOUBLE, or BFLOAT16.
    • workspaceSize (uint64_t *, output): size of the workspace to be allocated on the device.
    • executor (aclOpExecutor **, output): operator executor, covering the operator computation process.

  • Returns:

    aclnnStatus: status code. For details, see aclnn Return Codes.

   The first-phase API implements input parameter verification. The following errors may be thrown:
 161001 (ACLNN_ERR_PARAM_NULLPTR): 1. self, other, or out is a null pointer.
 161002 (ACLNN_ERR_PARAM_INVALID): 1. The data type of self or other is not supported.
