A new engine for macro-block based video processing is introduced in this paper. This engine increases efficiency, flexibility and extensibility of data generation for macroblock based video processing system. In the proposed system, a new specific instruction sets that can access data in pixel, line, block, macro-block or frame within a clock cycle are introduced. Thus, efficiency of video pro...

We consider the NP-hard no-wait flowshop scheduling problem with sequence-dependent setup times to minimize makespan. We propose a hybrid heuristic which combines the iterated greedy process with local search method based on a block swap operator. Experimental results show that the proposed heuristic is comparatively more effective than the existing metaheuristics.

This work describes a realistic performance prediction tool for the parallel block LU factorization algorithm. It takes into account the computational workload, communication costs and the overlapping of communications by useful computations. Estimation of the tool parameters and benchmarking are also discussed. Using this tool we develop a simple heuristic for scheduling LU factorization tasks...

Combinatorial optimization problems of scheduling belongs in most cases to the NP-hard class. In this paper we propose very effective method of construct parallel algorithms based on island model of coevolutionary algorithm. We apply block properties, which enable inter-island genetic operator to distribute calculations and shorten communication between processors. ?

© 2013 Zhuang Zhao et al. 677 In this paper, we first introduce a general architecture of an energy management system in a home area network based on a smart grid. Then, we propose an efficient scheduling method for home power usage. The home gateway (HG) receives the demand response (DR) information indicating the real-time electricity price, which is transferred to an energy management contro...

In this paper, we present a flash solid-state drive (SSD) optimization that provides hints of SSD internal behaviors, such as device I/O time and buffer activities, to the OS in order to mitigate the impact of I/O completion scheduling delays. The hints enable the OS to make reliable latency predictions of each I/O request so that the OS can make accurate scheduling decisions when to yield or b...

Coscheduling has been shown to be a critical factor in achieving efficient parallel execution in timeshared environments [12, 19, 4]. However, the most common approach, gang scheduling, has limitations in scaling, can compromise good interactive response, and requires that communicating processes be identified in advance. We explore a technique called dynamic coscheduling (DCS) which produces e...

This study introductions situation of video storage and the methods of video data management, then proposes a Scheduling Strategy algorithm based on Offset Cache (SSOC). According to the statistical information of data block buffer offset, through building a cloud environment and studying the storage layer’s video data storage of the cloud storage, the algorithm schedules on mastering the suppl...
