- The likely performance gains from parallelism based on the inserted annotations and the specified number of available cores.
- The potential effects of parallel overhead, including which parallel frameworks are worth investigating.
- The impact of changing the number of iterations and the iteration duration on performance of the selected site.
Running the Suitability Tool
- Within Microsoft Visual Studio*. Use theToolsmenu,Advisor Workflowtab, or the toolbar icons (see Using the Menu Items and Toolbars).
- Within theIntel AdvisorstandaloneGUI. Use theToolsmenu, theAdvisor Workflowtab, or the toolbar icons after you open a project.
- Using theadvixe-clcommand line. Specify the--collect optionafter you open a project.

Why do I need to Collect the Suitability Data?
- Typical values are from 1.0 toN, where 1.0 means the parallel program only runs as fast as the serial program, andNis the ideal case of perfect parallelism.
- Values less than 1.0 indicate that the parallel program spends more time doing parallel overhead work than it gains from parallelism. That is, the serial program runs faster than the parallel program.
