Automated usability evaluation of parallel programming constructs: nier track

Multicore computers are ubiquitous, and proposals to extend existing languages with parallel constructs mushroom. While everyone claims to make parallel programming easier and less error-prone, empirical language usability evaluations are rarely done in-the-field with many users and real programs. Key obstacles are costs and a lack of appropriate environments to gather enough data for representative conclusions. This paper discusses the idea of automating the usability evaluation of parallel language constructs by gathering subjective and objective data directly in every software engineer´s IDE. The paper presents an Eclipse prototype suite that can aggregate such data from potentially hundreds of thousands of programmers. Mismatch detection in subjective and objective feedback as well as construct usage mining can improve language design at an early stage, thus reducing the risk of developing and maintaining inappropriate constructs. New research directions arising from this idea are outlined for software repository mining, debugging, and software economics.
