Cloning code can cause project maintenance difficulties, weaken the robustness of the project, and the bugs contained in the cloned code can damage the entire project. The current Cloning code detection technology is either limited to detecting only a few clones of code, or requires very high detection time. And if you need to detect a lot of source code, the main memory of a machine may not be able to store all the information. The possibility research on the parallel operation of the Cloning Code detection technology, using the Cloning Code detection technology based on the program dependency graph, this technique can not only detect the syntactic cloning, but also detect the semantic cloning, propose a parallel subgraph isomorphism detection method and use mapre-duce parallel implementation, The experimental results greatly improve the running speed of the method.
