Improving power efficiency of processor and memory has recently received a lot of attention. However, most existing solutions concentrate on processor or memory separately and cannot combine well to simultaneously improve both. This paper presents a solution to improve both processor and memory power efficiency simultaneously through group scheduling (GS) which managing CPU frequency and memory rank...
Typical remote sensing image interpretation consists of large number of long-lived independent computation jobs such as calibration, correction, and transformation and computation. These time consuming jobs are suitable for execution in desktop grid with high performance commodity PCs for its lower cost and high management ability. In this paper, a framework of parallel remote sensing image interpretation...
Virtual machine technologies currently receive great interest both in industry and research communities. And it is one of the most important technologies for the coming Cloud Computing. We surveyed the CPU scheduling algorithms in Xen and VMWare systems, and found that both of them use a distinctive VCPUs running queue for each physical CPU, which is referred to Partition Queue Model (PQM) in this...
Virtual machines with advances in software and architectural support have emerged as the basis for enterprises to allocate resources recently. One main benefit of virtual machine is server consolidation. However, flexible and complex consolidation results in some unpredictable performance problems and introduces new requirements, such as proper configurations for scheduler and reasonable arrangements...
