Intel® VTune

Intel^® VTune™ Performance Analyzer helps you deliver fast software on the latest 64-bit multicore systems. Locate performance bottlenecks without recompilation and with very low overhead (under 5%). Analyze the results using a graphical interface integrated with Visual Studio* and .NET. Quickly drill down to the source to identify problematic lines of code. Tune multi-threaded code for optimum performance on today's multicore processors.

• Low Overhead Sampling Profiling

• Call Graph Profiling that determines calling sequences and graphically displays the critical path

• Counter Monitor quickly identify's system level performance issues

• Intel Tuning Assistant helps Increase productivity by providing advice based on extensive knowledge

Low Overhead Sampling Profiling - Event-based sampling finds your bottleneck with very low overhead (typically less than 5 percent) . Identify problems such as cache misses, branch mis-predictions, and bus bandwidth. Because it is system-wide, event-based sampling can be used to tune libraries and drivers as well as application programs . No special builds or instrumentation are required.

Find the Critical Path Using Call Graph Profiling - Call Graph determines calling sequences and graphically displays the critical path . It also shows you the context of the bottleneck . To be effective, you often need to know not only where the application is spending its time, but how it got there . See which functions took the most time to process or were blocked the longest.

Identify System Issues with Counter Monitor - Call Graph determines calling sequences and graphically displays the critical path . It also shows you the context of the bottleneck . To be effective, you often need to know not only where the application is spending its time, but how it got there . See which functions took the most time to process or were blocked the longest.

Tap Into an Expert Knowledge Base with Intel Tuning Assistant - Increase productivity using Intel Tuning Assistant to automatically provide advice based on an extensive knowledge base.

Visualize Threaded Application Behavior - Timeline view aids in understanding what threads are doing and how they interact. It pinpoints the exact location of performance issues in call stacks and source code to aid analysis.

Identify Parallel Performance Issues - Identifies the threads and synchronization objects which impact performance. It shows the distribution of work to threads and pinpoints load imbalances

Advanced Thread Profiling Functionality - OpenMP* analysis enables quick prototyping and estimation of the performance potential of different designs. It uses critical path analysis to help focus on more significant performance issues
