Analysis of Multi-Processor with Feed-Back Loops

The multi-processor system of the computer systems attracts our attention to the function, the reliability and the expansibility of the system structure. The multi-processor system is so flexible that is able to change the system structure with a given situation correlatively. As some processors process jobs which come into the system at the same time, various conflicts occur among the resources of the system. A harmful problem is risen from the fact which the capacity of each resource is limited to the reason mentioned above. At the first step of the analytic study for the multi-processor system, we consider the multi-processor feed-back model. Next, we investigate by this model the relation between CPU and I/O when the processing of the tasks are repeated several time. We describe the method for the analysis and the meaning of feed-back ratio α, and give the the results of this analysis.
