An Adaptive Query Execution System for Data Integration
Query processing in data integration occurs over network-bound, autonomous data sources. This requires extensions to traditional optimization and execution techniques for three re...

Wire Segmenting for Improved Buffer Insertion
Buffer insertion seeks to place buffers on the wires of a signal net to minimize delay. Van Ginneken [14] proposed an optimal dynamic programming solution (with extensions propose...

Evaluation of Mechanisms for Fine-Grained Parallel Programs in the J-Machine and the CM-5
er uses an abstract machine approach to compare the mechanisms of two parallel machines: the J-Machine and the CM-5. High-level parallel programs are translated by a single optimi...
