• More “computing paradigms we ought to pay attention to”

• “Tooting my future horn”

Paradigm 1: Autonomic/AdaptiveParadigm 1: Autonomic/Adaptive

• Yes we’ve looked at it some, e.g.:– Database design advisors

– Adaptive query processing

• But we can be more sweeping– Discard configure-compile-run mentality

– Embrace run-monitor-adapt-continue

• Widely applicable– Traditional query optimization to web-scale

information brokering and lots in between

Paradigm 2: Paradigm 2: Simple Local Decision-MakingSimple Local Decision-Making

• Provoked by a theory faculty candidate in distributed algorithms If each site makes a locally-optimal decision, how

far is it from the globally-optimal decision made by a know-it-all centralized site? (Answer: not far)

• Forget complicated and expensive distributed protocols– Simple independent decisions are good enough

Especially if you use Paradigm 1Paradigm 1 at the same time
