An Improved LP-based Approximation for Steiner Tree
The Steiner tree problem is one of the most fundamental ÆÈ-hard problems: given a weighted undirected graph and a subset of terminal nodes, find a minimum weight tree spanning ...

Interconnect modeling for improved system-level design optimization
Accurate modeling of delay, power, and area of interconnections early in the design phase is crucial for effective system-level optimization. Models presently used in system-level...

A Compiler-Based Approach for Improving Intra-Iteration Data Reuse
Intra-iteration data reuse occurs when multiple array references exhibit data reuse in a single loop iteration. An optimizing compiler can exploit this reuse by clustering (in the...
