When the window height does not allow display of both the scalability graph with check boxes and the grid of annotation data, use these links to switch between displaying either the scalability graphic with site-specific check boxes or the grid of annotation data. |
Scalability of Maximum Site Gain (scalability) graph |
View a graph of the selected site's predicted maximum gain. The number of CPUs appears on the X axis and the program's run-time performance gain appears on the Y axis. Near the top of each vertical line a CPU number, you will see a box and a circle that indicate the minimum and maximum predicted gain values. If the minimum-maximum range appears in the:
If the minimum-maximum range forms a flat line, this indicates that the maximum number of CPUs specified exceeds the number of task instances. You can set the Target CPU Count in the All Sites pane interactively to update the graph and associated values in the Suitability Report. You can set the default value for the Target CPU Count in the Options > General dialog box. Use this dialog box to choose the Maximum CPU Count, which specifies the X axis values in the scalability graph and limits the maximum value allowed for the Target CPU Count in the Suitability Report window (see the help topic Dialog Box: Options - General under See Also below). |
Overhead check boxes to the right of the scalability graph below Changes I will make to this site to improve performance. |
Determine whether changing these items will impact the site's Maximum Site Gain value and its impact on the Maximum Program Gain for All Sites displayed in the All Sites pane:
These check boxes help you plan which parallel overhead or chunking items will be worthwhile when you add parallelism to your program. In the Recommended column, if Yes appears, the Intel Advisor analysis predicts it may be worthwhile for you to reduce the parallel overhead or enable chunking when you add parallel framework code to this site. If you agree to do this, select that check box. After you modify the modeling assumptions for the selected site, values are automatically calculated and updated. Repeat this for each site in the All Sites pane. |
Column labels |
Click a column heading to sort in either ascending or descending order. |
A link: Click here to display the scalability graph A link: Click here to display annotation data |
Toggle between displaying the suitability graph or the annotation data. These links only appear when the height is insufficient to display both the scalability graph and the annotation data. |
Selected task data row |
Review the predicted characteristics of each task in each column of the data grid. The columns are:
