Hi,

Recently we have started seeing a lot more of the following in our profiles

[Unknown stack frame(s)] 17.773s [Unknown] [Unknown stack frame(s)]

How can we resolve what this is, as it is majority cost in the profile.

Thanks.

I may need to know more about the nature of the application you wish to analyze, The amplxe-cl command line being ran (how you are performing the analysis), the Intel VTune Amplifier XE and VTune version and update level, Compile method / switched, OS, etc. However, the document Resolving Unknown Frames may be of interest and may explain some of the behavior you are experiencing.
