event-based metrics: Event ratios with their own threshold values. VTune Amplifier collects event data, calculates the ratios, and provides the results in the corresponding columns of the Bottom-up/Top-down Tree windows and in the Summary window. As soon as the performance of a program unit per metric exceeds the threshold, the VTune Amplifier marks this value as a performance issue (in pink) and provides recommendations how to fix it. For the full list of metrics used by the VTune Amplifier, see the Hardware Event-based Metrics topic in the online help.
event skid: An event detected not exactly on the code line that caused the event. Event skids may even result in a caller function event being recorded in the callee function. See the online help for more details.
finalization: A process during which the Intel® VTune™ Amplifier converts the collected data to a database, resolves symbol information, and pre-computes data to make further analysis more efficient and responsive.
hotspot: A section of code that the processors spend a lot of time executing. Some hotspots may indicate bottlenecks and can be removed, while other hotspots inevitably take a long time to execute due to their nature.
viewpoint: A preset result tab configuration that filters out the data collected during a performance analysis and enables you to focus on specific performance problems. When you select a viewpoint, you select a set of performance metrics the VTune Amplifier shows in the windows/panes of the result tab. To select the required viewpoint, click the button and use the drop-down menu at the top of the result tab.
