Multiprocessor Scheduling for High-Variability Service Time Distributions
Many disciplines have been proposed for scheduling and processor allocation in multiprogrammed multiprocessors for parallel processing. These have been, for the most part, designed and evaluated for workloads having relatively low variability in service demand. But with reports that variability in service demands at high performance computing centers can actually be quite high, these discipline...
متن کاملQD-AMVA: Evaluating systems with queue-dependent service requirements
Workload measurements in enterprise systems often lead to observe a dependence between the number of requests running at a resource and theirmean service requirements. However, multiclass performance models that feature these dependences are challenging to analyze, a fact that discourages practitioners fromcharacterizingworkloaddependences. We here focus on closed multiclass queueing networks a...
متن کاملservice time variability and job scheduling fairness
Fairness is an inherent and fundamental factor of queue service disciplines in a large variety of queueing applications. Service time variability across jobs is an important factor affecting both system performance and scheduling rules (for example, computer systems that prioritize short jobs over long jobs). Service time variability and its effects on mean response times have been studied exte...
متن کاملThe AMVA Priority Approximation
Most computer systems contain one or more system resources whose usage is controlled on the basis of workload priorities. Unfortunately, the exact analysis of queueing network models incorporating priority scheduling disciplines is usually infeasible. The MVA Priority Approximation has been proposed as a comparatively inexpensive, and yet reasonably accurate, approximation technique for queuein...
متن کاملTechniques for enhancing real-time CORBA quality of service
End-to-end predictability of remote operations is essential for many fixed-priority distributed real-time and embedded (DRE) applications, such as command and control systems, manufacturing process control systems, large-scale distributed interactive simulations, and testbeam data acquisition systems. To enhance predictability, the Real-time CORBA specification defines standard middleware featu...
