Error Message: Cannot Open Data

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


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


Consider the following options:

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

    You may have two console windows: the first one for building the application and the second one for launching the VTune Profiler. The second console should run the application smoothly before attempting to launch the VTune Profiler. 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>/env/ for Linux* and vars.bat for Windows*. Once the application runs, start the VTune Profiler from that environment.

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