When this command is checked, you are telling TotalView that it should hold the thread. When it is unchecked, the thread can run when it receives a go command.
Hold (checked)
Holds the thread. This stops the thread and places a hold on it. Hold means that a go command cannot tell this thread that it should begin executing. Only after you release the thread is it eligible to run.
Release (unchecked)
Releases the thread. Releasing means that the thread will run if it subsequently receives a go or other run-level command.
NOTE >> These features are supported when your compiler used sprocs; for example, the MIPSpro OpenMP compiler.
For more information on processes and threads and their behavior while being stepped, see “Group, Process, and Thread Control” in the “TotalView Users Guide”.
