If you are looking to profile applications that use Intel® HD Graphics or Intel® Iris™ Graphics (referred to as GPU in this article) for rendering, video processing, and computations, the Intel® VTune™ Amplifier XE is the performance profiler for you. The Intel VTune Amplifier XE can monitor, analyze, and correlate activity on both the CPU and GPU.
VTune™ Amplifier XE Call Stack Pane
The call stack pane is displayed in viewpoints of analysis types that include stack data. It is displayed on the right side of the viewpoint (highlighted below in a gold box).
A global hot key is a mechanism whereby you associate a combination of keystrokes with an action. For example, on Windows* the key combination, “Ctrl-Alt-Del”, performs a system action. Both Windows* and Linux* have standard solutions for assigning an action to a key or key combination. By using VTune Amplifier XE’s command line scripting, it is possible to control the data collection and display of results using a global hot key.
