Performance modeling and automatic ghost zone optimization for iterative stencil loops on GPUs
Iterative stencil loops (ISLs) are used in many applications and tiling is a well-known technique to localize their computation. When ISLs are tiled across a parallel architecture...

Cancellation of loads that return zero using zero-value caches
The speed gap between processor and memory continues to limit performance. To address this problem, we explore the potential of eliminating Zero Loads—loads accessing memory loc...

High-performance regular expression scanning on the Cell/B.E. processor
Matching regular expressions (regexps) is a very common workload. For example, tokenization, which consists of recognizing words or keywords in a character stream, appears in ever...
