云計(jì)算是一種允許用戶托管應(yīng)用程序或使用計(jì)算資源的一種按目標(biāo)付費(fèi)的模型?蛻艨梢愿鶕(jù)網(wǎng)絡(luò)服務(wù)的樣式來(lái)訪問(wèn)這些應(yīng)用程序和計(jì)算。云提供商提供的這些產(chǎn)品可以被廣泛地分類為:軟件即服務(wù)(SaaS)、平臺(tái)即服務(wù)(PaaS)和基礎(chǔ)設(shè)施即服務(wù)(IAAS)。能耗是云計(jì)算面臨的最重要的挑戰(zhàn)之一,因?yàn)檫@些云應(yīng)用的數(shù)據(jù)中心Web服務(wù),浪費(fèi)了大量的能量。高科技應(yīng)用程序,包含數(shù)以千計(jì)的任務(wù)將在虛擬化云中執(zhí)行,以獲得更多收益。增加云系統(tǒng)的處理能力用于執(zhí)行這些任務(wù),同時(shí)也增加了云系統(tǒng)的計(jì)算能力。如何降低云計(jì)算數(shù)據(jù)中心的能耗成為學(xué)術(shù)界和工業(yè)界共同關(guān)注的問(wèn)題。本文中,我們專注于在異構(gòu)計(jì)算環(huán)境中調(diào)度獨(dú)立任務(wù)的問(wèn)題,考慮整體計(jì)算能量的最小化。我們提出綠色建議,所給出的計(jì)算解決方案并不總是只能夠最小化計(jì)算能量,而是進(jìn)一步減少環(huán)境污染物。為了解決這些問(wèn)題,我們給任務(wù)分配適當(dāng)?shù)奶摂M機(jī)。如果能夠滿足任務(wù)的截止期約束,我們把任務(wù)安排在最慢的虛擬機(jī)上,同時(shí)最小化。能源消耗;谒紤]問(wèn)題的相關(guān)特性和性質(zhì),我們建立了針對(duì)優(yōu)化目標(biāo)和約束條件的數(shù)學(xué)模型,提出了一種啟發(fā)式算法。啟發(fā)式算法由三個(gè)部分組成:任務(wù)排序、VM搜索和任務(wù)映射。為了驗(yàn)證所提...
