You can start Thread Analyzer by using the tha command.
The Thread Analyzer interface is the Performance Analyzer (analyzer) interface that is streamlined for multithreaded program analysis. Instead of the usual Performance Analyzer views, you see the Races, Deadlocks, and Dual Source views. If you use Performance Analyzer to look at multithreaded program experiments you see the traditional Performance Analyzer views such as Functions, Callers-Callees, Disassembly, along with the views for data races and deadlocks.
