the Grid is an interconnected set of distributed compute servers. An application running on the Grid consists of processes, which can be executed in parallel or in a sequential manner. An application can specify application level and network level Quality of Service parameters including number of processors, memory, special software, network bandwidth, delay, jitter, packet loss, etc. We investigate the question: Which processes arc allocated to which compute servers that collectively satisfy the application's resource requirements and optimize performance and cost parameters. We describe a protocol to identify those compute servers that can execute the application with minimal cost and provide the required application level and network level Quality of Service.

In order to resolve the composite material multi-objective topology optimization in aircraft design, a multi-objective aircraft optimization system based on grid technology, the multi-objective optimization grid (MOOG) is put forward. Using grid middleware, MOOG pooled the distributed computational resource into a high-performance computing platform and built a common genetic algorithm computational model towards multi-objective topology optimization. this system provided uniform resource service and visible user using interface. this thesis discussed in detail the system design and the improved multi-objective genetic algorithm. Finally, the solid experimental results of optimizing one type of high aspect ratio wing show that the MOOG has reduced the computation time and has good parallel acceleration.

the Simple Object Access Protocol (SOAP) is recognized as a more promising middleware for electronic commerce applications among other leading candidates such as CORBA. the redundant nested invocation (RNI) problem arises when servers in a replicated group issues nested invocations to other server groups in response to a client invocation. Automatic suppression of RNI from active group is always a desirable function, yet this function usually requires careful if not complex design. In our previous work, we have proposed a 3-tier RNI suppression mechanism to solve this problem. In this work, we propose a automatic configuration and single-tier suppression mechanism to improve the performance. Our approach is portable so that the web service running on our platform is able to interact with any other SOAP applications. Our preliminary experiments show that the proposed auto-suppression mechanism is efficient in most cases.
