| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Multi-server systems are popular due to their scalability and cost effectiveness. To fully utilize a multi-server system, one would need to analyze the performance of the multi-server system under various scheduling and dispatching policies. A popular approach for analyzing the performance of a computer system is to model the behavior of the computer system by a Markov chain. However, the analysis of the Markov chain is often intractable, particularly when the state space of the Markov chain grows in multiple dimensions. In this talk, we review a technique to reduce the dimensionality of a Markov chain that can model the behavior of a multi-server system. The dimensionality reduction is applied to a performance analysis of a particular task assignment policy with cycle stealing. Cycle stealing allows us to assign tasks to servers more effectively, and the dimensionality reduction of Markov chains allows us to quantitatively evaluate the performance improvement by cycle stealing. | |
