Abstract
An analysis and visualization is used to depict how a concurrent application executes threads on processor cores over time. With the analysis and visualization, a developer can readily identify thread migrations and thread affinity bugs that can degrade performance of the concurrent application. An example receives information regarding processes or threads running during a selected period of time. The information is processed to determine which processor cores are executing which threads over the selected period of time. The information is analyzed and executing threads for each core are depicted as channel segments over time, and can be presented in a graphical display. The visualization can help a developer identify areas of code that can be modified to avoid thread migration or to reduce thread affinity bugs to improve processor performance of concurrent applications.
