Debugging information (PDB files on Windows* and DWARF format on Linux*) for applications and system modules is not generally available on the system by default. Missing debug information is not critical to performance analysis but prevents
Intel® VTune™from providing full-scale statistics on call stacks, source data, and so on.
VTunedoes not find debug information for the binaries, it statically identifies function boundaries and assigns hotspot addresses to generated pseudo names
func@for such functions, for example:
If a module is not found or the name of a function cannot be resolved, the
VTunedisplays module identifiers within square brackets, for example:
If the debug information is absent, the
VTunemay not unwind the call stack and display it correctly in the
Call Stackpane. Additionally in some cases, it can take significantly more time to finalize the results for modules that do not have debug information.
For accurate performance analysis, you are recommended to have the debug information available on the system where the
VTuneis installed. See detailed instructions to enable:
