Identifying a Group Using a Letter
Use one of TotalView’s predefined sets, each identified by a letter. For example, the following command sets the focus to the workers group:
dfocus W
Table 10 defines the group specifiers, which must be in uppercase:
 
Table 10: Arena group specifiers
Group specifier
Target of command
C
Control group
All processes in the control group containing the process of interest.
D
Default control group
All processes in the control group containing the process of interest. This is the same as the C group specifier except that it’s not displayed with the arena.
S
Share group
The set of processes in the control group that have the same executable as the process of interest.
W
Workers group
The set of all worker threads in the control group containing the process of interest, which typically contains threads from multiple processes.
L
Lockstep group
A set that contains all threads in the share group that have the same PC as the arena’s thread if interest. If you step these threads as a group, they proceed in lockstep.
