MPI parallel programming system based on visual modeling and automatic skeleton code generation method

The invention discloses an MPI parallel programming system and an automatic generation method for framework code, which are based on visual modeling. A model is provided by a user interface layer based on a visual operating interface; a code generating layer is used for analyzing the model, wherein, the user interface layer consists of a graphic editor used for graphical modeling and a code editor used as the modifying environment for generating a code framework; the code generating layer comprises a arithmetic framework module, a model verifying module and a code generating module, wherein, the arithmetic framework module is used for describing features and actions of a mode, encapsulating the design mode once again and providing a program framework; the model verifying module is used for verifying the logical correction of the model before the code is generated; and the code generating module is used for invoking different parallel standard lib according to users' different demands.
