Research of parallel component composition and performance optimization based on agent technology

In order to better assemble and optimize the performance of parallel component programs, this paper designed and used different software agents. The component connection agents were responsible for the component interface bonding and data redistribution. The component execution agents and resource management agents cooperated with each other to deploy the components on the computing nodes that meeted the requirements. This paper defined four adaptive strategies. Different component adaptive agents, component execution agents and resource management agents cooperated with each other to complete the adaptive process of component and improve the performance of component. Resource management agent, load detection agent and component execution agent cooperated with each other to complete the load balancing work and improve the performance and throughput of the whole computing platform. Experiments on heterogeneous computer clusters demonstrate the effectiveness of the proposed parallel component assembly and performance optimization methods based on agent technology. Compared with the traditional performance optimization methods, the method based on agent technology is flexible and has performance advantages.
