Abstract


In order to solve practical engineering optimization design problems of excessive , shorten design cycles, reduce cost optimization , and full use of existing computing resources , combined with the computer industry of distributed object technology to achieve an optimal design for distributed computing systems . Distributed computing systems are in structural optimization of combined distributed computing, distributed object technology, computer network , finite element analysis methods , structural optimization and other related disciplines based on the research design and developed . Currently structural optimization design is usually done on a single computer , but the stand-alone computing power is limited after all . The authors developed an optimized system design task distribution to multiple computers within the LAN simultaneously , thereby greatly improving the computational speed and full use of existing computing resources. Through this system, users can connect through the network multiple computers as a supercomputer , it has more than one CPU and more memory . The system is responsible for the development of the supercomputer inside each CPU management , computing tasks allocation and data transmission , while these functions are fully transparent to the user , that user does not care about these , the user can focus on optimizing the parameters of the task set and the final calculation results. The DCOM -based distributed system specification , DCOM is Microsoft 's specification , located on different computers to support communication between objects . The main work topics are as follows : 1. Through the current field of computer optimization design disciplines and distributed object technology research, the distributed computing introduced to optimize the design disciplines . (2) the actual development of a DCOM-based distributed computing systems for structural optimization , and through several numerical examples carried out have proved the feasibility and efficiency of the system .
