Intel® VTune™ Performance Analyzer

Intel® VTune™ Performance Analyzer for Windows* - No Samples in Expected Module

Symptom(s):

When viewing collected sampling data, some modules are not represented by samples.

Solution:
When the Intel® VTune™ Performance Analyzer cannot identify to which module a particular sample belongs, it places the sample in a pseudo-module called Other32 (or Other64). The VTune analyzer only tracks modules that were loaded by the operating system, so things like power management in the BIOS and self-generating code are not tracked.

  • Microsoft Windows* (XP, Vista, 7)
  • Intel® VTune™ Performance Analyzer
  • Intel® VTune™ Performance Analyzer for Windows* - Call Graph only instruments and displays the exported functions of your DLL

    Symptom(s):

    The VTune™ Performance Analyzer identifies your DLL as a system DLL. As a result, only exported functions are instrumented.

    Cause:

    The DLL is located in a address that the VTune analyzer recognizes as a system address. System address ranges are set as follows:

  • Microsoft Windows* (XP, Vista, 7)
  • Intel® VTune™ Performance Analyzer
  • Intel® VTune™ Performance Analyzer 8.0 for Linux* - Error: "driver ioctl failed" when Using VTune™ Analyzer for Linux*

    Symptom(s):

    If you run sampling collection on systems under the Eclipse GUI when per CPU Buffering is enabled and you get an error message: "driver ioctl failed," the sampling driver will be unusable.

    Cause:

    The VTune™ analyzer sampling driver currently has issues when sampling using the Eclipse GUI (vtlec) under Per CPU Buffering mode on "-sn2" and "-rtgfx" SGI ProPack4 SP3 kernels. This issue will be fixed in a subsequent release of the analyzer.
