| Outline of Final Research Achievements |
In this research, I developed a method for processor utilization in a heterogeneous distributed system, which consists of : (i) derivation of the lower bound of the work load for each processor to be assigned for parallel execution, (ii) task assignment, (iii) task scheduling. Conventional task scheduling algorithms for heterogeneous systems have one serious drawback, i.e., they can not achieve a high degree of processor utilization because they assign an averaged scheduling priority for each task and then a good response time can not be obtained in a system having high heterogeneity. From experimental results by the simulation, it can be concluded that the proposed algorithm in this research outperforms other conventional task scheduling algorithms in terms of both the response time and efficiency.
