We apply Amdahl's Law to multicore chips using symmetric cores, asymmetric cores, and dynamic techniques that allows cores to work together on sequential execution. To Amdahl...
With faster CPU clocks and wider pipelines, all relevant microarchitecture components should scale accordingly. There have been many proposals for scaling the issue queue, registe...
The current multiprocessors such asCray T3D support interprocessor communication using partitioned dimension-order routers (PDRs). In a PDR implementation, the routing logic and sw...
Intuitively, aggressive work sharing among concurrent queries in a database system should always improve performance by eliminating redundant computation or data accesses. We show...

We use graphical models to explore the question of how people learn simple causal relationships from data. The two leading psychological theories can both be seen as estimating th...
