Attach Options
On the Debug Options tab, two options exist:
*Enabling ReplayEngine, which is an option available to all other debugging sessions.
*Placing the processes to which you are attaching into a control group under the Attach Options area.
 
 
If you have selected a group in previous TotalView sessions and the group exists in the dropdown, it is selected for you. Otherwise, the default is to create a new group to contain all processes attached to in this session.
