Coscheduling through Synchronized Scheduling Servers - A Prototype and Experiments
Predictable network computing still involves a number of open questions. One such question is providing a controlled amount of CPU time to distributed processes. Mechanisms to control the CPU share given to a single process have been proposed before. Directly applying this work to distributed programs leads to unacceptable performance, since the execution of processes on distributed machines is not coordinated in time. This paper discusses how coscheduling can be achieved with share-controlling scheduling servers. The performance impact of scheduling control is evaluated for BSP-style programs. These experiments show that synchronization mechanisms are indispensable and that coscheduling can be achieved for unmodi ed programs, but also that a performance overhead has to be paid for the control over CPU share.
