Presentation Transcript

  1. Lecture Topics: 12/6 • Selected OS Hot Topics • Cluster computing • Power management • Mobile computing

  2. Cluster Computing • Examples: • Global Memory Service (GMS) • Beowulf • Why buy a million-dollar supercomputer if you can get the same results from a cluster of cheap PC’s? • May also be better for reliability, upgradeability, *ility • Type of research: kernel hacking, application rewriting

  3. Power Management • Examples: • Palm Pilot/Milly Watt project • CMU Energy-aware project • The more general problem: resource management • Can problem be meaningfully solved at OS level? • Type of research: soldering irons and multimeters, kernel hacking

  4. Mobile Computing • Examples: • Bayou • Wearable computing • Communication paradigm is completely different: contact is intermittent, lossy, and dynamic • Can we get work done anyway? • Type of research: laptops and Ricochet modems, fancy eyeglasses and pocket-sized keyboards
