Configuring Analysis Type
- About Configuring Analysis Type
- Configuring Sampling Interval
For a user-mode sampling and tracing custom collection, configure the amount of wall-clock time the Intel® VTune™ Amplifier waits before collecting each sample (sampling interval).
- Collecting Stack Data for Event-based Sampling Analysis
- Analyzing Idle/Active Power Consumption
Configure the Intel® VTune™ Amplifier to collect special metrics and analyze idle and active power consumption of your system and the impact your software has on the system behavior.
- Configuring Sample After Value
- Collecting Call Count Data
Enable the stack collection for the hardware event-based sampling analysis and configure the Intel® VTune™ Amplifier to statistically approximate the number of calls to sampled functions.
- Adding Events
If required, edit a list of hardware events monitored by the Intel® VTune™ Amplifier for your processor by modifying an existing or creating a new hardware event-based sampling analysis configuration.
- Configuring an Analysis Type for Intel® Xeon Phi™ Coprocessor
On Intel® Xeon Phi™ coprocessors (code name: Knights Corner), configure the Intel® VTune™ Amplifier either to run the predefined Hotspots, General Exploration, or Memory Bandwidth analysis types, or create a custom analysis type with an arbitrary set of hardware events.
- Configuring MPI Application Analysis
Use the Intel® VTune™ Amplifier command line interface (
amplxe-cl) to configure and run performance analysis of an MPI application.
- Analyzing Frames
Configure the Intel® VTune™ Amplifier to detect the Frame API calls in your code and analyze performance per frame, where frame is the time period between frame begin and end points.
- Analyzing Tasks
Configure the Intel® VTune™ Amplifier to focus your performance analysis on a task - program functionality performed by a particular code section.
- Adding External Data to the Intel® VTune™ Amplifier
Integrate performance statistics collected externally into a VTune Amplifier analysis result and correlate data provided by your external collector and VTune Amplifier metrics.
