Collective Operations Profile
The Collective Operations Profile enables you to analyze communication patterns that are done using MPI Collective Operations. Like the Message Profile (see Message Profile), the Collective Operations are also represented in a color-coded matrix format. The default matrix shows the type of the Collective Operation as the row label and the process as the column label.
The precision of the values shown can be adjusted as explained in the Message Profile section.
Place the mouse over any point in the matrix and see the detailed information for the current cell in the View status bar in the form $AttributeValue ($RowLabel, $ColumnLabel). It enables you to get exact attribute values even if the cells are configured to be very small or to show no alphanumerical entries at all.
