S-Check

Abstract

S-Check is a novel tool for identifying performance bottlenecks in parallel and networked programs. It is a highly-automated sensitivity analysis tool for programs that extends benchmarking and conventional profiling. It predicts how refinements in parts of a program are going to affect performance by making local changes in code efficiencies and correlating these against overall program performance. This analysis is a sophisticated comparison that catches interactions arising from shared resources or communication links. S-Check's performance assessment ranks code segments (bottlenecks) according to their sensitivity to the code efficiencies changes. This ranked-ordered list serves as a guide for tuning applications. In practice, S-Check code analysis yields faster parallel programs.
