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

Abstract

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. Compared with the prior art, the system and the method have good universality, so that even the professional staff without professional knowledge can have the code framework generated automatically via the method of visual modeling.

Problems solved by technology

[0005] Some of the systems and methods in the above-mentioned prior art are too low in abstraction, requiring parallel programmers to pay too much attention to the underlying details, such as message passing, synchronization, adding and subtracting locks, etc., resulting in low programming efficiency and many program code errors ; Some cannot meet the latest application and system requirements; some have the defects of poor portability and scalability; some are for special fields, such as aerodynamic simulation, solving partial differential equations, etc., so the versatility is very poor
