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.
Configure the Intel® VTune™ Amplifier to get highly accurate CPU time data in the user-mode sampling and tracing results.
Enable call stack data collection for hardware event-based sampling analysis types.
Use the Intel® VTune™ Amplifier command line interface (
amplxe-cl) to configure and run performance analysis of an MPI application.
For applications using Processor Graphics, configure the Intel® VTune™ Amplifier to monitor, analyze, and correlate the application performance on both the CPU and GPU.
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.
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).
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.
