Stopping Processes and Threads

To stop a group, process, or thread, select a Halt command from the Group, Process, or Thread pulldown menus in the menubar.

CLI: dhalt Halts a group, process, or thread. Setting the focus changes the scope.

The three Halt commands differ in the scope of what they halt. In all cases, TotalView uses the current thread, which is called the thread of interest or TOI, to determine what else it will halt. For example, selecting Process > Halt tells TotalView to determine the process in which the TOI is running. It then halts this process. Similarly, if you select Group > Halt, TotalView determines what processes are in the group in which the current thread participates. It then stops all of these processes.

For more information on the Thread of Interest, see “Defining the GOI, POI, and TOI”.

When you select the Halt button in the toolbar instead of the commands in the menubar, TotalView decides what it should stop based on what is set in the toolbar pulldown list.

After entering a Halt command, TotalView updates any windows that can be updated. When you restart the process, execution continues from the point where TotalView stopped the process.
