.. index:: pair: page; Add .. _doxid-dev_guide_op_add: Add === General ~~~~~~~ Add operation performs element-wise addition operation with two given tensors applying multi-directional broadcast rules. .. math:: \dst(\overline{x}) = \src_0(\overline{x}) \mathbin{+} \src_1(\overline{x}), Operation attributes ~~~~~~~~~~~~~~~~~~~~ =========================================================================================================================== =========================================================== =========== =============================== ===================== Attribute Name Description Value Type Supported Values Required or Optional =========================================================================================================================== =========================================================== =========== =============================== ===================== :ref:`auto_broadcast ` Specifies rules used for auto-broadcasting of src tensors. string ``none`` , ``numpy`` (default) Optional =========================================================================================================================== =========================================================== =========== =============================== ===================== Execution arguments ~~~~~~~~~~~~~~~~~~~ The inputs and outputs must be provided according to below index order when constructing an operation. Inputs ------ ====== ============== ===================== Index Argument Name Required or Optional ====== ============== ===================== 0 ``src_0`` Required 1 ``src_1`` Required ====== ============== ===================== .. note:: Both src shapes should match and no auto-broadcasting is allowed if ``auto_broadcast`` attributes is ``none``. ``src_0`` and ``src_1`` shapes can be different and auto-broadcasting is allowed if ``auto_broadcast`` attributes is ``numpy``. Outputs ------- ====== ============== ===================== Index Argument Name Required or Optional ====== ============== ===================== 0 ``dst`` Required ====== ============== ===================== Supported data types ~~~~~~~~~~~~~~~~~~~~ Add operation supports the following data type combinations. ========== ========== ===== Src_0 Src_1 Dst ========== ========== ===== f32 f32 f32 bf16 bf16 bf16 f16 f16 f16 f32 bf16, f16 f32 bf16, f16 f32 f32 s32 s32 s32 ========== ========== ===== Implementation Notes ~~~~~~~~~~~~~~~~~~~~ Add supports in-place operations, meaning that ``src_0`` can be used as both input and output. In case of in-place operation, the original ``src_0`` data will be overwritten. This support is limited to cases when data types of ``src_0`` and ``dst`` are identical. Use in-place operations whenever possible for performance.
