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™

Profiler

from providing full-scale statistics on call stacks, source data, and so on.

If the

VTune

Profiler

does not find debug information for the binaries, it statically identifies function boundaries and assigns hotspot addresses to generated pseudo names

func@

address

for such functions, for example:

If a module is not found or the name of a function cannot be resolved, the

VTune

Profiler

displays module identifiers within square brackets, for example:

[module]

.

If the debug information is absent, the

VTune

Profiler

may not unwind the call stack and display it correctly in the

Call Stack

pane. 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

VTune

Profiler

is installed. See detailed instructions to enable:
