Web Service-based Open Distributed Computing Solver

As the booming and evolution of network technology, Web-Service applies greatly in the area of commercial software, Web Service is a capsulated entity released to network which affords a functional set for other programs, When the service is running, the client call the service, it is not necessary to know the realization mechanism detail, just need get the service interface.Currently, Web Service is not mature enough but evolutive greatly. The paper shows the special advantage in formulating distribution application system, and at the same time, introduces the main technology in designing and realizing distribution system. In the first part, it puts forward the scheme of the Web-Service based on architecture of open distribution computation solver according to the main character and advantage of each technology. The scheme make full use of the network resource of software and hardware, and make the multi-solver in network solve a equation constrained problem by working coordinately each other. The paper researches the three problems of the scheme: (1) the architecture of distribution computation solver; (2)the constitutes of the solver component, namely how to design a wrapper problem for solver; (3)the conversion between mathematic expression and DOM(Documental Object Model).Because the same mathematic semantic probably express in various character and description structure in various system., there must be a conversion transform a various format mathematic semantic description into the same format in DOMMathML(DOM for MathML).Finally, the paper simplify the model architecture,and integrate, test and release for the system after simplified model.
