Cluster scheduling, where processors are grouped into clusters and the tasks that are allocated to one cluster are scheduled by a global scheduler, has attracted attention in multiprocessor real-time systems research recently. In this paper, by adopting optimal global schedulers within each cluster, first we investigate the worstcase utilization bound for cluster scheduling. Specifically, for a system...
Recently, the negative effect of the popular power management technique Dynamic Voltage and Frequency Scaling (DVFS) on the system reliability has been identified. As a result, various reliability-aware power management (RAPM) schemes have been studied for uniprocessor real-time systems. In this paper, we investigate global scheduling-based RAPM (G-RAPM) schemes for a set of frame-based real-time...
Power management has become a very important research area and various approaches have been proposed. As an energy-efficient architecture, chip multiprocessor (CMP) has been widely adopted by chip manufacturers. In this paper, we study power management schemes for real-time systems on block-partitioned multicore platforms, where the processing cores are grouped into different blocks and cores on one...
