PPT : How Computer Architecture Trends May Affect Future Distributed Systems
Content Inside :
Three Questions
* What is a System Area Network (SAN)
and how will it affect clusters?
o E.g., InfiniBand
* How fat will multiprocessor servers be
and how to we build larger ones?
o E.g. Wisconsin Multifacet’s Multicast & Timestamp Snooping
* Future of multiprocessor servers & clusters?
o A merging of both?
Technology Push: Moore’s Law
* What do following intervals have in common?
o Prehistory to 2000
o 2001 to 2002
* Answer: Equal progress in absolute processor speed
(and more doubling 2003-4, 2005-6, etc.)
o Consider salary doubling
* Corollary: Cost halves every two years
o Jim Gray: In a decade you can buy a computer
for less than its sales tax today
Application Pull
* Should use computers in currently wasteful ways
o Already computers in electric razors & greeting cards
* New business models
o B2C, B2B, C2B, C2C
o Mass customization
* More proactive (beyond interactive) [Tennenhouse]
o Today: P2C where P==Person & C==Computer
o More C2P: mattress adjusts to save your back
o More C2C: Agents surf the web for optimal deal
o More sensors (physical/logic worlds coupled)
o More hidden computers (c.f., electric motors)
* Furthermore, I am wrong
