Setting and Creating Custom Groups
This section presents a series of examples that set and create groups. To create a custom group, use the command dgroups.
You can use the following methods to indicate that thread 3 in process 2 is a worker thread:
dset WGROUP(2.3) $WGROUP(2)
Assigns the group ID of the thread group of worker threads associated with process 2 to the WGROUP variable. (Assigning a nonzero value to WGROUP indicates that this is a worker group.)
dset WGROUP(2.3) 1
This is a simpler way of doing the same thing as the previous example.
dfocus 2.3 dworker true
Adds the threads in the indicated focus to a workers group.
dset CGROUP(2) $CGROUP(1)
dgroups -add -g $CGROUP(1) 2
dfocus 1 dgroups -add 2
These three commands insert process 2 into the same control group as process 1.
dgroups -add -g $WGROUP(2) 2.3
Adds process 2, thread 3 to the workers group associated with process 2.
dfocus tW2.3 dgroups -add
This is a simpler way of doing the same thing as the previous example.
Following are some additional examples:
dfocus g1 dgroups -add -new thread
Creates a new thread group that contains all the threads in all the processes in the control group associated with process 1.
set mygroup [dgroups -add -new thread $GROUP($SGROUP(2))]
dgroups -remove -g $mygroup 2.3
dfocus g$mygroup/2 dgo
The first command creates a new group that contains all the threads from the process 2 share group; the second removes thread 2.3; and the third runs the remaining threads.
