Use the Intel® VTune™ Amplifier for performance analysis on local and remote Linux* target systems.

To analyze your Linux target, do the following:

  1. Prepare your target application for analysis:

    • Enable downloading debug information for system kernels by installing debug info packages available for your system version.

    • Enable downloading debug information for the application binaries by using the -g option when compiling your code. Consider using the recommended compiler settings to make the performance analysis more effective.

    • Build your target in the Release mode.

    • Create a baseline against which you can compare the performance improvements as a result of tuning.

      For example, you instrument your code to determine how long it takes to compress a certain file. Your original target code, augmented to provide these timing data, serves as your performance baseline. Every time you modify your target, compare the performance metrics of your optimized target with the baseline, to verify that the performance has improved.

  2. Prepare your target system for analysis:

  3. Create a VTune Amplifierproject and run the performance analysis of your choice.
