Overview
Intel® Thread Profiler 3.0 for Windows*

Intel® Thread Profiler 3.1 for Windows* helps you tune multi-threaded applications faster, for optimal performance on Intel® multi-core processors.

Intel® Thread Profiler is available as a standalone product. For a more complete performance tuning solution it is also included with VTune™ Performance Analyzer for Windows.


Features
Visualize Threaded Application Behavior:
Timeline view aids in understanding what threads are doing and how they interact.
Pinpoint the exact location of performance issues in call stacks and source code to aid analysis.
Measure the number of cores that are effectively utilized by the application to determine actual parallel performance.

Intel Thread Profiler 3.1 for Windows shows both the concurrency and timeline views simultaneously to help you visualize what percent of code is optimally parallel and where application performance issues exist. In Figure 1, two source code fixes resulted in continued performance improvement with each revision, illustrated by the shortening of the application runtime. Intel Thread Profiler enables developers to make their applications multi-core ready.
