scheduling aimed at capturing some key aspects of energy minimization. In this model, each job is to be executed between its arrival time and deadline by a single processor with variable speed, under the assumption that energy usage per unit time, P, is a convex function of the processor speed s. We give

with an algorithm that consists of three phases: task creation, task assignment and parallel task execu-tion. In order to reduce CPU- and I/O-cost, the three phases are processed in a fashion that pre-serves spatial locality. Dynamic load balancing is achieved by splitting tasks into smaller ones and reassigning

Abstract—In single-threaded processors and Symmetric Multiprocessors the execution time of a task depends on the other tasks it runs with (the workload), since the Operating System (OS) time shares the CPU(s) between tasks in the workload. However, the time accounted to a task is roughly the same

Traditional processor scheduling mechanisms in operating systems are fairly rigid, often supportingonly one fixed scheduling policy, or, at most, a few "scheduling classes" whose implementations are closely tied together in the OS kernel. This paper presents CPU inheritance scheduling, a

. In this work we present the structure of a user-level processor a scheduler implemented on top of IRIX6.5, to which, we will refer as CpuManager. The CpuManager will provide us a total control of the scheduling of the applications. This control will include the scheduling policies and the mechanism to carry

Design narrative of an efficient CPU architecture dedicated to UTS-DSP (University of Tehran and Iran Communication Industries(SAMA) DSP) [1]-[10] is reported. Time and area consuming, the CPU architecture is a critical component of the overall architecture, which is responsible for execution

coherent on-die 2 nd level cache allows efficient inter-processor communication and high-bandwidth local data access by CPU cores. Task scheduling is performed entirely with software in Larrabee, rather than in fixed function logic. The customizable software graphics rendering pipeline for this

CPU subunits over minutes of SPEC2000 and desktop workload execution. As an example application, we use the generated component power breakdowns to identify program power phase behavior. Overall, this paper demonstrates a processor power measurement and estimation methodology and also gives

Power dissipation is increasingly important in CPUs ranging from those intended for mobile use, all the way up to highperformance processors for high-end servers. While the bulk of the power dissipated is dynamic switching power, leakage power is also beginning to be a concern. Chipmakers expect
