Error Message: Cannot Open Data

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

Cause

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

Solution

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 <>/env/vars.sh
     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.
