Performance Analysis Using Automatic Grouping

Abstract

Performance has become an important and difficult issue for software development and maintenance on increasingly parallel systems. To address this concern, teams of developers use tracing tools to improve the performance, or track performance related bugs. In this work, we developed an automated technique to find the root cause of performance issues, which does not require deep knowledge of the system. This approach is capable of highlighting the performance cause, using a comparative methodology on slow and fast execution runs. We applied the solution on some use cases and were able to find the specific cause of issues. Furthermore, we implemented the solution in a framework to help developers working with similar problems.
