The following are some additional examples:
Setting Group Focus
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
These three commands define a new group that contains
all the threads in the process 2 share group except
for thread 2.3, and then continue that set of
threads. The first command creates a new group that
contains all the threads from the share group; the second
removes thread 2.3; and the third runs the remaining
threads.
Using the g Specifier: An Extended Example
The meaning of the g width specifier is sometimes not clear when it is coupled
with a group scope specifier. Why have a g specifier when you have
four other group specifiers? Stated in another way, isn’t something like gL
redundant?
The simplest answer, and the reason you most often use the g specifier, is
that it forces the group when the default focus indicates something different
from what you want it to be.
The following example shows this. The first step sets a breakpoint in a multithreaded
OMP program and execute the program until it hits the breakpoint.
