  11. Disney: Large-scale rendering • “San Fransokyo” contains 83,000 buildings, 260,000 trees, 215,000 streetlights, and 100,000 vehicles. City detail is based on assessor data from San Francisco • Rendered in four geographically-distributed datacenters • 55,000 CPU cores, 400 TB of memory • Many system failures! https://www.engadget.com/2014/10/18/disney-big-hero-6/ http://www.electronicdesign.com/blog/disney-supercomputer-renders-big-hero-6

  13. Google Chrome: More complex than you think! http://szeged.github.io/sprocket/architecture_overview.html

  14. Google Chrome: More complex than you think! • Performance considerations: browsing the web should be fast • Architecture considerations: new web technologies are enabling sophisticated web applications Multithreaded javascript (web workers) • HTML5 media APIs • High-performance 3D graphics via OpenGL/WebGL • Even raw assembly execution! (WebAssembly) • • Security considerations: we need to keep your bank account safe from shady websites • The modern browser is sort of its own operating system!

  16. Course website https://cs110.stanford.edu

  17. CS 110 • This class is well-oiled… • But also somewhat of an experiment • I have never taught CS 110 before • CS 110 has never been taught over the summer (by anyone) • The course scheduling and lecture pacing are somewhat of an experiment • Weekly surveys: nominal amount of extra credit

  18. Ways to get help • O ff ice hours • Piazza • Slack • Summer Academic Resource Center • Email me if you need more resources or support!

  19. Assignment policies • We generally won’t look at your code • No late days • Assignments turned in within 24 hours of the deadline are capped at 90% • Assignments turned in within 48 hours of the deadline are capped at 60%

  20. Labs / discussion sections • Optional • Thursdays and Fridays • Start this week! Sign up on the course website
