Barrier Breakpoint States

Processes and threads at a barrier point are held or stopped, as follows:

Held

A process or thread that is held cannot resume execution until all the processes or threads in its group are at the barrier, or until you manually release it. The various go and step commands from the Group, Process, and Thread menus have no effect on held processes.

Stopped

When all processes in the group reach a barrier point, TotalView automatically releases them. They remain stopped at the barrier point until you tell them to resume executing.

You can manually release held processes and threads with the Hold and Release commands contained within the Group, Process, and Thread menus. When you manually release a process, the go and step commands become available again.

You can reuse the Hold command to again toggle the hold state of the process or thread. See Holding and Releasing Processes and Threads for more information.
