Embodiment Construction

[0032] MPI is a message passing standard in a high-performance parallel computing environment based on message passing. It has been widely adopted by universities, research institutions and industries on high-performance parallel computing hardware platforms such as cluster systems and workstation networks, and has become a de facto message. Pass standard specification. Various existing MPI implementation versions, such as MPICH, CHIMP, LAM and other function libraries, have achieved good results in high-performance parallel computing in LAN and WAN environments. Therefore, the MPI standard is also adopted in the parallel programming of the present invention.

[0033] The MPI parallel program design and frame code automatic generation system can generate a message-passing-based parallel program code frame on the basis of the created model. Users only need to add more specific algorithm details to develop a complete and runnable source code for parallel applications. The plat...

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.
