ParaProf Preferences Window

The preferences window allows the user to modify the behavior and display style of ParaProf's windows. The font size affects bar height, a sample display is shown in the upper-right.

The Window defaults section will determine the initial settings for new windows. You may change the initial units selection and whether you want values displayed as percentages or as raw values.

The Settings section controls the following

  • Show Path Title in Reverse - Path title will normally be shown in normal order (/home/amorris/data/etc). They can be reverse using this option (etc/data/amorris/home). This only affects loaded trials and the titlebars of new windows.

  • Reverse Call Paths - This option will immediately change the display of all callpath functions between Root => Leaf and Leaf <= Root.

  • Statistics Computation - Turning this option on causes the mean computation to take the sum of value for a function across all threads and divide it by the total number of threads. With this option off the sum will only be divided by the number of threads that actively participated in the sum. This way the user can control whether or not threads which do not call a particular function are consider as a 0 in the computation of statistics.

  • Generate Reverse Calltree Data - This option will enable the generation of reverse callpath data necessary for the reverse callpath option of the statistics tree-table window.

  • Show Source Locations - This option will enable the display of source code locations in event names.
