Identifying a Group Using a Letter

TotalView : TotalView User Guide : PART III Parallel Debugging : Group, Process, and Thread Control : Arenas and P/T Sets : Group Specifiers in P/T Sets : Identifying a Group Using a Letter

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 15 defines the group specifiers, which must be in uppercase:

Table 15: 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.
