Group Specifiers in P/T Sets
This section extends the arena specifier syntax to include groups, building on the discussion in
Process and Thread Width Specifiers in a P/T Set.
If you do not include a group specifier, the default is the control group that contains the POI. The CLI displays a target group in the focus string only if you set it to something other than the default group.
You most often use target group specifiers with the stepping commands, as they give these commands more control over what to step.
Add groups to an arena specifier using this format:
[width_specifier][group_specifier][dpid][.dtid]
If you enter only one element, TotalView determines other values based on the current focus. Identify a group using a letter, number, or name.
