Performs a Reduce operation, including SUM, MIN, and MAX. This API is asynchronous.

aclError aclrtReduceAsync(void *dst, const void *src, uint64_t count, aclrtReduceKind kind, aclDataType type, aclrtStream stream, void *reserve)

Parameter	Input/Output	Description
dst	Input	Pointer to the destination memory address.
src	Input	Pointer to the source memory address.
count	Input	Size of the source memory, in bytes.
kind	Input	Operation type.
type	Input	Data type. The Atlas A3 training products/Atlas A3 inference products support the following data types: int8, int16, int32, fp16, fp32, and bf16. The Atlas A2 training products/Atlas A2 inference products support the following data types: int8, int16, int32, fp16, fp32, and bf16. The Atlas 200I/500 A2 inference products supports the following data types: int8, int16, int32, fp16, and fp32. The Atlas inference products supports the following data types: fp32, fp16, and int16. The Atlas training products supports only the fp32 data type.
stream	Input	Stream for executing the Reduce operation task. To use the default stream, pass NULL.
reserve	Input	Reserved. Currently, the value is fixed to NULL.

0 on success; else, failure. For details, see aclError.

dts and src must be on the same device as stream.
