  1. 多核技术的机遇与挑战 The Challenges and Opportunities of the Multi-Core System Bob C. Liang 梁兆柱 博士 Chief Research Officer 首席研发官 Intel Software & Solutions Group PRC 英特尔中国软件与解决方案事业群 2007年11月23日

  2. Agenda • The MulticoreTera-scale computing and the Accelerating Software Spiral • Opportunities and Challenges • A new leveled playing field for Research and Education Innovation

  3. Era ofTera-ScaleComputing 10’s to 100’sof cores “Tera-leap to Parallelism” Quad-Core ENERGY-EFFICIENT PERFORMANCE Dual Core Hyper-Threading Single-core, single-thread TIME

  4. Intel’s ASCI Option Red Intel has a long tradition of leading in TeraScale computing First Terascale chip: 2007 First Terascale computer: 1997 10 years Intel’s 80 core research chip 9000 CPUs one megawatt of electricity. 1600 square feet of floor space. One CPU 67 watt 275 mm2 But this great hardware is useless without software Source: Intel

  6. Innovation opportunity - Multicore Software Parallelism • Opening New Global Markets Multi-Core Open Source Open Source Application Virtualization

  7. Applications Integration Backup/Recovery Solution Business Intelligence PBX1000 Downloads/day ERP1.2M Downloads Office Tools800K Downloads/month 550K Developers, 23M+ Websites Development Tools Web Servers 69% MSS Server Solution Stack Application Servers 9M Downloads, 31% MSS Databases Est. 10M Installations Operating Systems Linux, ~30% Server MSS Growing Business Models with Open Source

  8. Mobile Internet • - Wireless • Graphic • Power Open Source Across All Segments Enterprise Mobile Home Health • Performance • Power • Virtualization; Server & Client • Embedded IT • Personal Health • Embedded Linux • Consumer Electronic Devices

  9. Innovation opportunity - Multicore Software Parallelism Multi-Core Open Source Application Virtualization • Enabling the next generation data center

  10. Server Virtualization is now considered a mainstream… • IT bullish in future use: driving 45% server use in 12 months • IDC Directions 2007 Feb-07 • Autonomic Continuity • VM Migration VMM VMM HW HW App 3 App 4 App 2 App 1 OS OS OS OS • Dynamic Data Center • Agility, responsiveness VMM VMM HW HW VMM HW • Fault tolerance • Mission critical apps on volume servers App App App App App App App App App VMM VMM HW HW OS OS OS OS OS OS OS OS OS • Virtual Clients • Client cost reduction • Data security VMM HW VMM HW Virtualization is here Consolidation R&D Production Test & Development

  11. Applications Solution Stack Infrastructure KVM OEMs Growing Virtualization Ecosystem

  12. Innovation opportunity - Multicore Software Parallelism Multi-Core An Example in Graphics Open Source Application Virtualization

  13. Rasterization Streams of Triangles flows to GPU Effects require tedious multi-pass techniques Ray Tracing Flexible Scalable process Reliable, true reflections shadows and more Extremely Compute intensive Graphics - Rasterization Vs Ray Tracing

  14. Physical Simulation • Physical simulation very broad domain • Huge number of phenomena • e.g., water in pool very different from water in pipe • Each can be modeled in various levels of detail Prof. Ron Fetkiw Stanford Univ.

  15. But, We need Parallelization Game Straightforward (parallelized via nested loops) Algorithm Change (original algorithm not amenable to efficient threading) Production

  16. Innovation opportunity - Multicore Software Parallelism Think Parallel Multi-Core Innovation headroom will Come from parallelism Open Source Application Virtualization

  17. Services and Solutions Middleware Runtime Development Tools Performance Tools OS Virtualization/VMM UEFI/BIOS Parallelism Research – Keep Perspective of the Vertical Stack Services/Solutions Drive Technology Innovation

  18. What we are doing to help • Help mainstream programmers to quickly develop quality code • ACCELERATE TRANSITIONTO PARALLEL PROGRAMMING

  19. SOFTWARE COLLEGE TRAINING & forums ANALYSIS TOOLS find parallelism, tune parallelism Libraries andCompilers award winning parallelism support DEBUGCONCURRENCY CORRECTNESS Complements a larger family of products,all designed for parallel programming

  20.
