There is a problem with Vtune troubled me a few days as specific as bellows. I will be very grateful if someone can help me to solve this problem.
The tool version is Intel Vtune amplifier xe 2013 update2 evaluation version (noncommercial license), which was download from intel official web site.The purpose is to use Vtune to measure the required bandwidth of my application. My CPU is Intel Core i7 2600, whose architeture is sandy bridge. My OS is redhat enterprise linux 6.2. The Vtune mode used is GUI.
The problem is: when I choose analysis type, I choose "sandy bridge / ivy bridge" -> "General Exploration" and ticked the "Analyze memory bandwidth". After finished anaylsis, it displayed "Analysis is completed" and "Finalization completed successfully". But in the "Summay", id displayed "Elapsed time: 0.000s", and the viewpoint button is only one option to choose, which is "Task Time", and not my wanted "bandwidth". as the Vtune Help document says, there would be a "bandwidth" option.
Then I shoosed the "bandwidth" type, get the same result.
I want to know, if my evaluation version or my CPU cannot support harware event-based sampling collection, or there is something must be set but I igored.
Is there someone knows, thanks!
