Random Quantum Allocation: A new approach to waiting time distributions for M/M/N processor sharing queues [chapter]

Jens Braband, Rolf Schaßberger
1993 Messung, Modellierung und Bewertung von Rechen- und Kommunikationssystemen  
This approach can be used for the numerical approximation of waiting and response time distributions for processor sharing queues.  ...  These queues are approximated by sequences of models featuring a new natural discipline called Random Quantum Allocation (RQA) operating in discrete time.  ...  Our answer is the Random Quantum Allocation (RQA) model, which in contrast to the RR model gives up the ordering of the customers in the queue.  ...

, Jens Waiting time distributions for closed M/M/N processor sharing queues.  ...  The actual computation of waiting time distribution for the model is accomplished by two independent methods, namely the random quantum allocation (RQA) approach and the numerical inversion of the LST.  ... 

Uncovering CPU load balancing policies with harmony

Joseph T. Meehean, Andrea C. Arpaci-Dusseau, Remzi H. Arpaci-Dusseau, Miron Livny
2013 Proceedings of the ACM International Conference on Computing Frontiers - CF '13  
We introduce Harmony, a system for extracting the multiprocessor scheduling policies from commodity operating systems.  ...  Our analysis uncovers the strengths and weaknesses of each of these schedulers, and more generally shows how to utilize Harmony to perform detailed analyses of complex scheduling systems.  ...  a busy target would instead be represented as [m, m, m, n], where m > n.  ...

Utility Accrual Dynamic Routing in Real-Time Parallel Systems

Mehdi Kargahi, Ali Movaghar
2010 IEEE Transactions on Parallel and Distributed Systems  
MEU is compared with some well-known Dynamic Routing (DR) policies for different TUF shapes and both cases of homogeneous and heterogeneous processors of a two-queue system.  ...  In this paper, we propose an exact analytical solution for performance evaluation of dynamic policies used for routing of TUF-constrained Firm Real-Time (FRT) jobs among parallel single-processor queues  ...  ACKNOWLEDGMENT The authors wish to thank anonymous referees for their valuable comments and careful review of the paper.  ...

Scalable Task Schedulers for Many-Core Architectures

Anuj Pathania
2018
This thesis develops schedulers for many-cores with different optimization objectives.  ...  The proposed schedulers are designed to be scale up as the number of cores in many-cores increase while continuing to provide guarantees on the quality of the schedule.  ...  Unfortunately, with the reduction in size of a transistor with introduction of every new technology node the leakage power of a processor continued to rise due to quantum effects such as quantum tunneling  ...

A Foreground-Background queueing model with speed or capacity modulation [article]

Andrea Marin, Isi Mitrani
2021
Job service times have a two-phase Coxian distribution and the second phase is given lower priority than the first.  ...  The models studied in the steady state involve two queues which are served either by a single server whose speed depends on the number of jobs present, or by several parallel servers whose number may be  ...  The M/M/n model with two preemptive priority queues was studied by Mitrani and King [18] , by Gail at al. [8] and by Kao and Narayanan [12] .  ...

The authors do not provide a notation for their queueing system, but given from the information in the text, it boils down to a M/M/n queue for the entire router.  ...  Mayer et al [14] show this figure, but finally model only the CPU as an M/M/n queue.  ...
