Comparison Collective Operations Profile

The Comparison Collective Operations Profile is similar to the regular Collective Operations Profile. The values shown in the cells are calculated using the currently selected comparison operation shown in the title of the Chart. The comparison operation can be switched from the context menu or from the settings dialog.

Regarding missing values and unmappable column or row labels the Comparison Collective Operations Profile behaves identically to the Comparison Message Profile.

Old Interface

To define a new symbol, first determine which value has to be used for the symbol handle, and then call the VT_symdef() function, passing the symbol and activity names, plus the handle value. It is not necessary to define the activity itself. Make sure to not use the same handle value for different symbols.

VT_symdef

int VT_symdef (int statehandle, const char * symname, const char * activity)
