Adjusting Time Slices to Apply Coscheduling Techniques in a non-dedicated NOW
MetadataShow full item record
Our research is focussed on keeping both local and parallel jobs together in a time-sharing NOW and efficiently scheduling them by means of coscheduling mechanisms. In such systems, the proper length of the time slice still remains an open question. In this paper, an algorithm is presented to adjust the length of the quantum dynamically to the necessity of the distributed tasks while keeping good response time for interactive processes. It is implemented and evaluated in a Linux cluster.
