Error Message: Cannot Open Data

Error message: Cannot open data. Intel® VTune™ Amplifier has faced a serious problem.

Cause

The data collection period could be too short (for example, <10ms), so that the VTune Amplifier could not capture performance data.

Solution

Consider the following options:

  • Verify that you can run your application without the VTune Amplifier.

    You may have two console windows: the first one for building the application and the second one for launching the VTune Amplifier. The second console should run the application smoothly before attempting to launch the VTune Amplifier. If you see an error message reporting problems with loading shared libraries on the second console, set up the environment correctly either via the LD_LIBRARY_PATH variable or by running source <install_dir>/amplxe-vars.sh for Linux* and amplxe-vars.bat for Windows*. Once the application runs, start the VTune Amplifier from that environment.

  • If the analysis duration is too short, increase the workload for your application.
