Basically, the Tuning Assistant is telling you that there is not enough information to deduce any problems. When you create an activity with the Sampling Wizard, you have the option to tell the assistant how many runs to use to collect information. If you selected "One sampling run...", then you need to create a new activity and select "A few sampling runs..." or "Many sampling runs...". This will give the assistant more information from which to deduce the problem.
Regarding call graph, did you receive a message about your application not having base relocations? If you application is not linked with "/fixed:no", or otherwise has base relocations turned off, call graph will not be able to instrument your application and, consequently, there will be no data collected or displayed for it. See the online help for more info.
Hello and thanks for answering.
I can't seem to find the "A few sampling runs..." or "Many sampling runs..." option you speak of. I'm using VTune 7.0.
As for the call graph problem, I figured it out. Yes I was linking with '/fixed:no' except my compiler only pays attention to this when typed in capitals! :$
Oh, sorry. Yes, these options are new to 7.1. If you purchased 7.0 and registered your serial number, you should be entitled to a free upgrade. Based on your purchase date, you receive one year of support services, including free upgrades. The 7.1 installation package can be downloaded from http://premier.intel.com.
