Abstract: Programming models like MPI or OpenMP are not suitable for largescale Internet environments because of scalability or parallel grain issues. In this paper, a novel parallel programming model in largescale Internet environments called Wide Area Programming Model (WAPM), which provided a feasible way for parallel programming, was designed and implemented. WAPM includes three modules: communication library, communication protocol and application programming interface. WAPM is a good programming model, and is strongly supported by its general programming, adaptive parallelism and fault tolerance. An example application was also demonstrated with WAPM on a specific distributed computing platform. In order to testify the efficiency of WAPM, a serial of simulation experiments were done. The results obtained from performance analysis show that WAPM is a general and feasible approach for parallel programming.
