Opportunities for Flow Based Parallelism —— A Case Study of Three Open Source Applications

This paper investigates open source applications to seek for oppor- tunities of flow-based parallelization. Domain of streaming appli- cation are targeted such as sentence parsing, image processing and data packet investigation. Component flow of application is iden- tified and profiling is conducted to discover bottleneck of program executions. After parallelization attempt, challenges of flow-based parallelization are identified and discussed.unpublishedis peer reviewe
