Migrating to Processor Sharing
This paper describes experiences gained while adding processor sharing capabilities to the ARCADE distributed system. The goal of a processor sharing facility (PSF) is to allow busy users to take advantage of cycles available on idle processors, which are typically plentiful in a network of individually-owned machines. Several researchers have reported positive experiences with implementing a P...
متن کاملModelling Restricted Processor Sharing
In principle unrestricted processor sharing can be very useful when jobs with widely varying CPU requirements are competing for the same processor. Even if there are several processors available, processor sharing can be useful. However, in practice it must be implemented by round-robin, and there is an overhead cost (e.g., cache thrashing) to implementing this scheme. Furthermore, the overhead...
متن کاملBeyond Processor-centric Operating Systems
By the end of the decade, computing designs will shift from a processor-centric architecture to a memorycentric architecture. At rack scale, we can expect a large pool of non-volatile memory (NVM) that will be accessed by heterogeneous and decentralized compute resources [3, 17]. Such memory-centric architectures will present challenges that today’s processor-centric OSes may not be able to add...
متن کاملBatch Arrival Processor-Sharing with Application to Multi-Level Processor-Sharing Scheduling
We analyze a Processor-Sharing queue with Batch arrivals. Our analysis is based on the integral equation derived by Kleinrock, Muntz and Rodemich. Using the contraction mapping principle, we demonstrate the existence and uniqueness of a solution to the integral equation. Then we provide asymptotical analysis as well as tight bounds for the expected response time conditioned on the service time....
متن کاملProcessor-Sharing Queues and Resource Sharing in Wireless LANs
In the past few decades, the processor-sharing (PS) model has received considerable attention in the queueing theory community and in the field of performance evaluation of computer and communication systems. The scarce resource is simultaneously shared among all users in these systems. PS models are used for modeling resource sharing mechanisms and have many applications in communication netwo...
