I am new to Vtuen, want to know some basic concepts. How exactly sampling works? what's the co-relation ship between Instructions and Clockticks? Which one should we used to identify hotspot?
Can someone point me to the basic answer?
You may want to read the book "VTune Performance Analyzer Essentials" by James Reinders (ISBN 0-9743649-5-9) which is an excellent treatise on VTune .
You may also want to check out the "Help->Show-me Demos" available once you launch VTune . If you are interested in Thread Profiler tutorial, please access it using "Help->Getting Started Tutorials".
If you have any additional questions, just ask. :)
