How to use it

[butalc]

Hi

I am new to VTune I am getting very frustrated with VTune. I amunableto get more than basic info about my application performance (hotspots). Also I am unable to use VTune from dev. studio - it crashes when it runs out of memory. VTune by itself also isnt stable - it crashes in 1 out of 3 executions.

My questions are:

-is there some simple guide forbeginnerusers of VTune,

-how do view tuning assistant output (I am unable to find clockticks event),

-why shouldnt I enable all events,

My environmnet:

-i7, 8GB ram

-win 7 x64

Hi,

First at all, please make sure that you are using latest version v9.1 U8.

For the beginning user, please use sampling wizard (with default PMU events) and call graph wizard, follow normal buttons.

Event name "clockticks" is for P4, "CPU_CLK_UNHALTED.THREAD" is for Corei7 processors.

The user can review all supported events by modifying sampling activity.

If the usermet crash in Visual Studio* or in standalone app - most likely some components are not installed/loaded successfully, the user should uninstall/reinstall the product.

The user can also use vtl command line to collect performance (read this article) andinterpret the result on VTune Analyzer.
