Dynamic Scheduling of a Multiclass Fluid Model with Transient Overload
We study the optimal dynamic scheduling of different requests of service in a multiclass stochastic fluid model that is motivated by recent and emerging computing paradigms for Internet services and applications. In particular, our focus is on environments with specific performance guarantees for each class under a profit model in which revenues are gained when performance guarantees are satisf...
متن کاملScheduling Transient Overload with the TAFT Scheduler
Nearly all known real-time scheduling approaches rely on the knowledge of Worst Case Execution Times (WCETs) for all tasks of the system. This is a severe restriction, as with today’s complex systems it becomes increasingly more expensive to determine WCET by applying analytical methods and the computed results often turn out to be a very pessimistic upper bound for the observed execution time....
متن کاملTransient analysis of multiclass manufacturing systems with priority scheduling
Scope and Purpose--Markov chains constitute the basic stochastic model underlying most performance evaluation studies in the area of manufacturing systems. Analysis of Markovian models has traditionally emphasized steady-state or equilibrium performance in preference to transient performance. Several studies over the years have, however, shown that transient analysis is also relevant. Most such...

Acknowledgements I would like to express my sincere gratitude to my advisor, Professor Jim Dai for his direction, support and feedback. His genius, patience and deep insights make it a pleasure to work with him. I also acknowledge the help and support of the other members of my committee, Professors Georgia Tech, students and faculty, for their support and help. I would especially like to thank...
متن کاملScheduling Solutions for Coping with Transient Overload 1
For most computer systems, even short periods of overload degrade performance signi cantly. The number of jobs in the system quickly grows, often exceeding the capacity of the system within just seconds, and response times explode. In this paper we investigate system behavior under transient overload. We nd that the poor behavior of systems under transient overload can at least partly be attrib...
