Datacenters are facilities used to house computer systems. These facilities generally consume a large amount of energy. In recent years, many researches proposed datacenter management frameworks that allow energy to be utilized more efficiently. However, most of these frameworks were limited by constraints related to unpredictable behaviors of applications in both the perspectives of execution time...
Workload characterization is an important concept in performance tuning and efficiency improvement of high performance computing systems. Not only does it allow a system to dynamically adjust resources, it also helps improve energy efficiency resulting in lower cost for computation. Nevertheless, lack of quantitative methods to describe workload characteristics prevents the system to work at its full...
The energy cost of a typical data center is usually much higher than those standard office buildings. Inefficiency in energy management can thus hurt a company. Currently, there are many commercial software that emphasize how to measure and control the energy usage. However, most of these available packages are not able to accurately predict behaviors of various applications submitted to a data center...
