Function: get_overflow_status

aclError aclrtGetOverflowStatus(void *outputAddr, size_t outputSize, aclrtStream stream)

ret = acl.rt.get_overflow_status(outputAddr, outputSize, stream)

Obtains the overflow status of tasks on all streams in the current context and copies the status value to the device memory allocated by the user. This API is asynchronous.

The Atlas 200/300/500 Inference Product does not support this API.

outputAddr: int, device memory allocated by the user, which needs to be allocated by calling acl.rt.malloc. To view data on the host, call acl.rt.memcpy or acl.rt.memcpy_async to transfer data from the device to the host.

outputSize: int, size of the device memory to be allocated, in bytes. The fixed size is 64 bytes.

stream: int, pointer address of a stream to deliver an overflow status query task.

ret: int, error code.

• 0 indicates success.
• Other values indicate failure.

This API is asynchronous. The API call delivers a task rather than executes a task. After this API is called, call the synchronization API (for example, acl.rt.synchronize_stream) to ensure that the task is complete.
