For Linux* target systems, enable analysis of Intel® Media SDK tasks execution over time.
For Intel® Xeon Phi™ coprocessors (code name: Knights Corner), configure the Intel® VTune™ Amplifier either to run the predefined Advanced Hotspots, General Exploration, or Bandwidth analysis types, or create a custom analysis type with an arbitrary set of hardware events.
Enable the stack collection for the hardware event-based sampling analysis and configure the Intel® VTune™ Amplifier to statistically approximate the number of trip counts for sampled loops.
Use the Intel® VTune™ Amplifier command line interface (
amplxe-cl) to configure and run performance analysis of an MPI application.
For a custom event-based sampling data collection, set up the Sample After Value (SAV) that is a frequency with which the Intel® VTune™ Amplifier interrupts the processor to collect a sample during hardware event-based data collection. SAV is measured as the number of events it takes to trigger a sample collection.
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).
Configure the Intel® VTune™ Amplifier to focus your performance analysis on a task - program functionality performed by a particular code section.
