Setting Group Focus
The following are the group letters. These letters are in uppercase:
C Control group
All processes in the control group.
D Default control group
S Share group
W Workers group
All processes in the control group. The only difference between
this specifier and the C specifier is that this letter
tells the CLI not to display a group letter in the CLI prompt.
The set of processes in the control group that have the
same executable as the arena’s TOI.
L Lockstep group
The set of all worker threads in the control group.
A set that contains all threads in the share group that have
the same PC as the arena’s TOI. If you step these threads
as a group, they proceed in lockstep.
A Group Number You can identify a group by the number TotalView assigns to it. The following
example sets the focus to group 3:
dfocus 3/
The trailing slash tells TotalView that you are specifying a group number
instead of a PID. The slash character is optional if you’re using a group_letter.
However, you must use it as a separator when entering a numeric group ID
and a pid.tid pair. For example, the following example identifies process 2 in
group 3:
p3/2
A Group Name You can name a set that you define. You enter this name with slashes. The
following example sets the focus to the set of threads contained in process
3 that are also contained in a group called my_group:
dfocus p/my_group/3
About Arena Specifier Combinations
The following table lists what’s selected when you use arena and group
specifiers to step your program:
Specifier Specifies
aC All threads.
aS All threads.
aW All threads in all workers groups.
aL All threads.
Every thread is a member of a control group and a member of a
share group and a member of a lockstep group. Consequently, three
of these definitions mean “all threads.”
