  1. Lecture 12: Cloud Computing-A • Precocious fantasies • SETI

  2. “Web Surfing” • Your professor has a huge ego • (Ignore the paparazzi at the door) • He’s also very competitive • Second place is the first of many losers • He needs to know how often his name appears relative to other celebrities on the internet • How long will this take?

  3. “Web Surfing” • Your professor has a huge ego • (Ignore the paparazzi at the door) • He’s also very competitive • Second place is the first of many losers • He needs to know how often his name appears relative to other celebrities on the internet • How long will this take? FOREVER

  4. “Web Surfing” • My laptop just isn’t good enough • Not powerful enough • Not enough bandwidth to internet

  5. “Web Surfing” • My laptop just isn’t good enough • Not powerful enough • Not enough bandwidth to internet • What if I add another laptop?

  6. “Web Surfing” • My laptop just isn’t good enough • Not powerful enough • Not enough bandwidth to internet • What if I add another laptop? • Another 10 laptops?

  7. “Web Surfing” • My laptop just isn’t good enough • Not powerful enough • Not enough bandwidth to internet • What if I add another laptop? • Another 10 laptops? • 100?

  8. “Web Surfing” • I would need thousands and thousands of computers • How could I do that?

  9. “Web Surfing” • I would need thousands and thousands of computers • How could I do that? • Cloud computing!

  10. Introduction • Most computers aren’t used all the time • Idle throughout the day • Not using full capabilities • We should make use of these computers for our needs

  11. SETI • Search for Extraterrestrial Intelligence • You install the SETI software on your computer • When your computer is idle, SETI software processes radio signals

  12. SETI • Really has no idea what your computer is (initially) • Has no idea where it’s physically located • Has no idea when your computer will be available

  13. SETI • So what does the SETI software know? • Your processor • Type • Number of cores • Your IP address(es) • Some misc stuff • They’re just happy to get some more resources

  14. Bringing it home… • Image SETI to be “reverse cloud computing” • Your computer is the server • When you’re the client, you want machines • Physical location doesn’t matter • You don’t care about specs • …or you choose your servers with care • You don’t know what machines you’re going to get

  15. Input/Data • Having computers is nice • Where are they getting their input? • Generating it themselves? • Listening to something streaming live? • Using pre-generated data? • If you already have data files, you need to make sure the computers can access them • We’ll talk more about this next time

  16. Possible Tasks • Playing games • Jeopardy!, chess, etc • Speech recognition • Pure computation • UP3DR • Traveling salesmen (well, we do have a cloud)
