Specifying Arenas
A P/T identifier often indicates a number of groups, processes, and threads. For example, assume that two threads executing in process 2 are stopped at the same statement. This means that TotalView places the two stopped threads into
lockstep groups. If the default focus is process 2, stepping this process actually steps both of these threads.
TotalView uses the term arena to define the processes and threads that are the target of an action. In this case, the arena has two threads. Many CLI commands can act on one or more arenas. For example, the following command has two arenas:
dfocus {p1 p2}
The two arenas are process 1 and process 2.
When there is an arena list, each arena in the list has its own GOI, POI, and TOI.
