Version 8.3 Features

This section lists the changes made for version 8.3 of TotalView.

Improvements to the way TotalView launches MPI programs let you use TotalView with virtually every MPI library, even with those that were not configured for debugging.

TotalView now highlights changes to values displayed in the Variable and Expression List windows with a colored background.

Figure 1: Highlighted Change in the Variable Window

While this figure shows a simple variable, TotalView also highlights changed elements within compound variables such as structures and arrays.

Values in the Variable and Expression List windows have a Previous value hidden column that you can display. Use the control on the right side of the column headings to display a list of columns that you can display or hide.

When a process hits a breakpoint, TotalView highlights the breakpoint by placing an arrow over the breakpoint ID in the Action Points pane.

View > Show Across replaces View > Laminate in the Variable window's menus. This means the commands you will now use are View > Show Across > Process and View > Show Across > Thread.

You can now tell TotalView to show a variable across processes or threads by right-clicking on it in the Source Pane, then selecting either Across Processes or Across Threads from the context menu.

The Create Watchpoint command was added to the Action Points menu. As always, you can create a watchpoint from within the Variable window by selecting Tools > Create Watchpoint.

You can now set a watchpoint upon a variable’s memory address by right-clicking on the variable in the Source pane and then selecting Create Watchpoint from the context menu.

You can completely expand or collapse information in the Variable window by selecting an icon in the toolbar. The accelerators for these commands are Ctrl++ (that’s the control key and the + symbol) and Ctrl+- (which is the control key and the - symbol).

TotalView no longer stops by default when your program loads a library.

You can specify more than one core file on the command line and you can use wildcards in core file names.

There is a new Events View report within the Memory Debugger Heap Status tab.

Within the Memory Debugger’s File > Import Data dialog box, you can select multiple memory debugging (.mdbg) files.
