Function Usage

Obtains the value of the enabling flag and type of the atomic operation. For details, see Table 1.

Prototype

__aicore__ inline void GetStoreAtomicConfig(uint16_t& atomicType, uint16_t& atomicOp)

Parameters

**Table 1** Parameters
Parameter	Input/Output	Description
atomicType	Output	Atomic operation enabling flag. 0: no atomic operation. 1: enables the atomic operation, of the float data type. 2: enables the atomic operation, of the half data type. 3: enables the atomic operation, of the int16_t data type. 4: enables the atomic operation, of the int32_t data type. 5: enables the atomic operation, of the int8_t data type. 6: enables the atomic operation, of the bfloat16_t data type.
atomicOp	Output	Atomic operation type. 0: sum operation.

Returns

None

Constraints

This API must be used together with SetStoreAtomicConfig(ISASI) to obtain the value of the enabling flag and type of the atomic operation.

Example

AscendC::SetStoreAtomicConfig<AscendC::AtomicDtype::ATOMIC_F16, AscendC::AtomicOp::ATOMIC_SUM>();
uint16_t type = 0;        // Atomic operation enabling flag
uint16_t op = 0;         // Atomic operation type
AscendC::GetStoreAtomicConfig(type, op);
