Energy-efficient real-time scheduling for two-type heterogeneous multiprocessors

Efficient Scheduling of Soft Real-Time Applications on Multiprocessors

In soft real-time applications, tasks are allowed to miss their deadlines. Thus, less-costly scheduling algorithms can be used at the price of occasional violations of timing constraints. This may be acceptable if reasonable tardiness bounds (i.e., bounds on the extent to which deadlines may be missed) can be guaranteed. In this paper, we consider soft real-time applications implemented on mult...

Energy-Efficient Scheduling of Periodic Real-Time Tasks over Homogeneous Multiprocessors

Different from many previous energy-efficient scheduling studies, this paper explores energy-efficient multiprocessor scheduling of periodic real-time tasks with different power consumption functions. When the goal is on the minimization of energy consumption, we propose a 1.412approximation algorithm in the derivation of a feasible schedule. A series of simulation experiments was done for the ...

Adaptive energy-efficient scheduling for real-time tasks on DVS-enabled heterogeneous clusters

Developing energy-efficient clusters not only can reduce power electricity cost but also can improve system reliability. Existing scheduling strategies developed for energy-efficient clusters conserve energy at the cost of performance. The performance problem becomes especially apparent when cluster computing systems are heavily loaded. To address this issue, we propose in this paper a novel sc...

Cross-architecture prediction based scheduling for energy efficient execution on single-ISA heterogeneous chip-multiprocessors

Soft Real-Time Scheduling on Multiprocessors

UMAMAHESWARI C. DEVI: Soft Real-Time Scheduling on Multiprocessors. (Under the direction of Prof. James H. Anderson.) The design of real-time systems is being impacted by two trends. First, tightly-coupled multiprocessor platforms are becoming quite common. This is evidenced by the availability of affordable symmetric shared-memory multiprocessors and the emergence of multicore architectures. S...
