new to vtune, 2 questions.

[odedf]

Hi,

I am new to vtune. (Just installed the 8.0 version.)

Two very different questions.

1. Was able to run the first use wizard.

I would like to know the percentage of the time each function is active,

i.e. if the program is composed of a main that calls function f that is active 95% of the time, I would like to view the result as 100% main + 95% f rather then 5% main + 95% f. How is it done?

2. Is there a document describing a recommended a methodology to use the v-tune in order to optimizea codes performance?

Thanks,

Oded.

Hi Oded:

1. Actually, in the normal sampling views (i.e., not the Summary view generated by the first-use wizard), the results are displayed as percent of module, so if you use the Sampling wizard, I think you will see what you want.

2. On the Welcome page, select Help. You should see a Tuning Methodologies entry under the VTune Performance Analyzer Help on the left side, as well as a link toThe Tuning Metholdogy on the main help page.

Regards,
