  1. Real-Time System Software GroupLab 408Wireless Networking and Embedded SystemsLaboratoryVirtualization, Parallelization, Web Service 薛智文 Office 322 cwhsueh@csie.ntu.edu.tw http://www.csie.ntu.edu.tw/~chsueh/ 本實驗室的研究主要是以系統軟體設計為主, 目前的幾個主要的方向是虛擬化, 平行化, 與網路服務.

  2. The Real World Virtualized everywhere! We work on virtualization, multicore parallelization, and autonomous services Cloud Server Notebook 真實世界裡, 到處都充滿了與我們生活息息相關的電子資訊軟硬體產品, 像是手機、電腦與雲端上的伺服器及其服務等等. 透過這些產品, 資訊能夠流通得更便利更迅速. 虛擬化將這些軟硬體系統結合得更緊密, 多核心平行化將效能更提升,自主服務創造對大眾更有利的應用平台。 Desktop Mobile /23

  3. Fully Utilizing Hardware Virtualization etc Sharing H/W & S/W Resources Running Applications (x-platform) Security Cloud Workstation Consolidation • Virtual class • Virtual circuit • Virtual community • Virtual device • Virtual disk • Virtual host • Virtual keyboard • Virtual machine • Virtual market • Virtual memory • Virtual money • Virtual Private Network • Virtual reality • … Even realized on a PC! 許多東西都可以被虛擬化, 如虛擬光碟, 虛擬裝置, 虛擬記憶體, 甚至是一整台機器都可以被虛擬化, 也就是說在一台電腦上同時執行多個作業系統. 虛擬化的用途很多元, 能讓這些作業系統更充分地共享軟硬體資源, 是雲端系統與應用不可或缺的關鍵技術. Run multiple OSes simultaneously with flexible performance! /23

  4. Virtualization (V12N) on Cloud Client Devices • 90+% performance on PC  embedded systems • To run multiple OSes on a mobile phone… Break the limitation of OSes! 透過不同的技術與最佳化, 虛擬化在 PC 上可達到 90% 以上虛擬化前的效能,我們研究在嵌入式系統上的實現虛擬化.希望透過虛擬化來打破 OS 之間的界線, 將來能在手機上同時跑兩種 OS 來支援雲端的客戶端裝置. iPhone+Android is possible! /23

  5. 虛擬化專案 Play 3D on-line Game on a virtual machine. Demo Clips 這是我們產學合作的一個虛擬化專案, 在 NB 上以 Xen 跑多個虛擬機器 ( Win 7, XP, Linux, Android ) 與應用, 甚至可以跑魔獸世界. /23

  6. Optimizing Parallelizationon MulticorePlatform Batch-pipelining dependent tasks for up to 2x speed! 我們也研究多核心系統的平行化, 實作在 H.264 解碼上效果領先全球, 也可應用在多核心的虛擬化系統, 理論上達到最佳。 Achieved 260FPS(720P) for H.264 Decoding! Also applicable for HEVC(H.265). /23

  7. Seller Buyer Logistics Cash Flow ... WeOS: Emerge Our Services 網民當家作主,共創資訊價值! 日本 AutonomousID Autonomous Distributed Match Engine 京都 ... 東京 大阪 ... ... ... USA Seattle Internet ... 台北 台灣 DC LA ... ... 嘉義 ... ... 台南 ... 資訊技術與服務應當不被少數人把持, 每個網民應當可以當家做主, 共創資訊價值. 我們應用各種技術提供自主 AID, 打造自主的分散式配對引擎, 讓系統上擁有 AID 的個體, 能自主形成社群提供各項服務, 像是買賣, 推薦, 爆料, 等等… 方便分享並保留隱私, 形成我們自主共享永續的理想 Cloud OS. ... ... V12N to help G11N (I18N + L10N). /23

  8. Projects • Synchronization on cloud server and devices • Task migration using Linux container • Real-time compression on backbone traffic • WeOS • P2P architecture, Credit/Database design • Services • CSIE eSystem • UI/UX • Services /23

  9. Anyone would like to change to have real impact for ourselves are welcome! • You decide who you are, don’t just follow. • We do the right thing and do thing right. • Don’t worry. We can make it. • Contact me. /23
