dc.description.abstract為了增進應用程式執行時,性能與能源消耗的效率,學者們提出了新的硬體平台—異質多核心系統。 在異質多核心系統中,每一顆核心可以擁有不同的性能與功率。要運用異質多核心系統時,一個主要的問題是如何分配不同的核心資源給應用程式。在這篇論文當中,我們利用動態電壓頻率調整技術建立了一個虛擬的異質多核心系統,目的是為了得到物理上的功率測量資料。我們為一般的爪哇虛擬機器設計了一個執行緒管理員,這個執行緒的管理員將針對爪哇執行緒,利用硬體效能計數物件的資料實施模糊控制管理,目標是更好的能源使用效率。我們利用能源與執行時間的乘積作為能源使用效率的指標。主要的實驗結果包括:實施模糊控制管理的爪哇虛擬機器,在scimark.fft.large上取得能源使用效率的好處。並且,整體能源的使用是下降的。zh_TW
dc.description.abstractAsymmetric multicore systems had been studied as a new hardware platform toward performance power efficiency for the execution of application programs. Each core in the system has distinct performance and power characteristics. When exploiting asymmetric multicore systems, a major issue is to distribute threads to various cores. In this work, we build a pseudo asymmetric system by dynamic voltage frequency scaling (DVFS) mechanism on Intel core i7 920 for physical power measurement and implement a tool agent for regular JVM to form an asymmetric-aware JVM that supervises the execution of Java threads and migrates threads with fuzzy-control scheduler. For result inspection, we consider energy delay product (EDP) as a metric to reveal the compromise between performance and energy use. The major results include: Our fuzzy-control scheduler results in EDP benefit for scimark.fft.large and lower overall energy consumption.en_US
