Abstract
The specification provides a method includes: updating a depth value of a target node or a depth value of a downstream node of the target node; receiving a depth value sent by an upstream node of the target node, and comparing the depth value of the target node with the depth value sent by the upstream node of the target node; in response to that the depth value of the target node is less than the depth value sent by the upstream node of the target node, updating the depth value of the target node to the depth value sent by the upstream node of the target node; and in response to that the depth value of the target node is equal to the depth value sent by the upstream node of the target node, determining that a loop exists in a data dependency path including the target node.
