Intel® VTune™ Amplifier can calculate analysis-independent time spent within particular procedures and functions and within children (callees). This is the information for Self and Total time, respectively. The Bottom-up window shows only Self time. The Top-down Tree window and Source/Assembly window show Self time and Total time.
Intel® VTune™ Amplifier provides a mechanism to analyze code parallelism and power consumption using the hardware event-based sampling with the stack collection enabled. As soon as you created a VTune Amplifier project and specified your analysis target, follow these steps to enable the collection and analyze the data:
