Scheduling scheme and performance assessment for timely responsive service on cluster server
BU Chang-qing · Computer Engineering and Applications Journal · 2007
This paper presents three real-time scheduling schemes for cluster servers:centralized scheme,distributed scheme and pull-based distributed scheme.Distributed scheme deploys scheduling on the end-node,while the scheduling work of centralized scheme is on the front-nodes,and that makes the former has a greater scalability.Pull-based distributed scheme makes end-nodes ask for events and direct load balance by themselves,to improve the scalability and efficiency of real-time cluster system.Lots of experimental results have been presented,illustrating the three scheduling schemes are benefit for decreasing the response time and maximizing the system throughout.
