This paper focuses on the instruction fetch resources in a real-time SMT processor to provide an energy-efficient configuration for a soft real-time application running as a high priority thread as fast as possible while still offering decent progress in low priority or non-realtime thread(s). We propose a fetch mechanism, Fetch-around, where a high priority thread accesses the L1 ICache, and l...

An improved performance analysis of priority based scheduling algorithm for the ad hoc grid layer is presented in this paper. A priority queuing model is developed to reduce the execution time of the jobs. Here, jobs to be dispatched based on priority. Execution time is one prime metric proposed for the system. We have achieved the overall execution time for the proposed system for 25 jobs is7....

This theory can explain why bank debt is universally senior, consistent with the presence of conflict (lawyers) and absolute priority violations in financial distress: Better organized banks would more strongly contest priority in financial distress if they were junior. Because “deterrence” can reduce creditors’ total expenses in a priority contest, the ex post stronger lobbyist/litigant should...

As multi-core processors continue to scale, more and more multiple distributed applications with precedence-constrained tasks simultaneously and widely exist in multi-functional embedded systems. Scheduling multiple DAGs-based applications on heterogeneous multi-core processors faces conflicting high-performance and real-time requirements. This study presents a multiple DAGs-based applications ...

Work-stealing schedulers focus on minimizing overhead in task scheduling. Consequently, they avoid features, such as task priorities, which can add overhead to the implementation. Thus in such schedulers, low priority tasks may be scheduled earlier, delaying the execution of higher priority tasks and possibly increasing overall execution time. In this paper, we develop a decentralized work-stea...

We investigate priority setting and the global health agenda by analysing the control of diarrhoeal diseases (CDD). CDD was one of the 'twin engines' of the 1980s' child survival movement, but now has a low priority on the global health agenda, even though diarrhoeal diseases still claim around 1.5 million children annually. In this article, we develop a framework and four indicators of priorit...

We study the problem of priority inversion in distributed real-time and embedded systems and propose a solution based on a distributed version of the priority inheritance protocol (PIP). Previous approaches to priority inversions in distributed systems use variations of the priority ceiling protocol (PCP), originally designed for centralized systems as a modification of PIP that also prevents d...

The human visual system has a limited perception of detail. In immersive virtual reality systems, perceptually based computer graphics techniques are often used to optimize system performance. Priority rendering is a rendering technique used in conjunction with an Address Recalculation Pipeline virtual reality system, in order to reduce the overall rendering load. Further reductions to the over...
