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.

Figure 2 Drill to the Source Code to Identify Threading Issues

Identify Parallel Performance Issues:

Identify the threads and synchronization objects which impact performance
See the distribution of work to threads and pinpoint load imbalances

Advanced Thread Profiling Functionality:

OpenMP* analysis enables quick prototyping and estimation of the performance potential of different designs
Use critical path analysis to help focus on more significant performance issues

Microsoft Visual Studio* 2005 and 2008 Support:

Supports C++ applications developed using the Microsoft Windows* compilers in Microsoft Visual Studio* 2005 and 2008.

New in This Release

Support for the latest multi-core processors:

Optimize the performance of your multi-threaded application on the new Intel® Core™2 Duo and Intel® Core™2 Quad processors

Install and run on Microsoft Windows Vista*:

Analyze compiled 32 and 64-bit applications running on Microsoft Windows Vista*

Compatibility

Intel Thread Profiler 3.0 for Windows is compatible with today’s industry-standard development tools:

Microsoft Visual Studio* 2003, 2005 or 2008
