The students in the Technion university took some open source projects, optimized them using a variety of techniques including threading and microarchitecture level tuning and produced faster versions of these applications. The table below gives the projects they worked on. For each of these projects, we have complete source code for the optimized (threaded) version, design methodologyand performance results (before and after optimization).
