The Intel® Performance Tuning Utility is a cross-platform performance analysis tool set succeeding the VTune™ Performance Analyzer. Along with such traditional features of the VTune analyzer as identifying the hottest modules and functions of the application, tracking call sequences, identifying performance-critical source code, the Intel Performance Tuning Utility has new, more powerful capabilities of data collection, analysis, and visualization. Although most of those capabilities are developed by requests of experienced in performance tuning users, most of new features are easy to use for people who are new to performance tuning.
This version of the Intel Performance Tuning Utility introduces the following new features comparing with VTune Analyzer features:
- Statistical Call Graph
- Loop profiler
- Basic Block analysis
- Result difference
- Events over IP view
