A distributed problem solving environment (PSE) for scientific computing

摘要

A distributed problem solving environment (PSE) is proposed to help users solve partial differential equation (PDE) based problems in scientific computing. The system inputs a problem description and outputs a program flow, a C-language source code for the problem and also a document for the program. Each module is distributed on distributed computers. The PSE contains all the information of the problem, PDEs, discretization scheme, mesh information, equation manipulation results, designed program structure, variable and constant definitions and program itself. Therefore the documentation support module generates a document for the generated program and the problem itself in the PSE. The module liaison module generates an adapter module among the distributed PSE modules. The job execution service module deploys programs generated or prepared on distributed computer resources and helps users run the programs on the distributed computers. The concept of the distributed PSE extends the potential of conventional PSE systems.
