Barriers
An OpenMP* barrier defines a point in an application which every thread of a particular team has to reach before thread execution continues. For debugging OpenMP* applications, it is useful to display the barrier's state, the number of threads that reached the barrier, the barrier's location, or other internal OpenMP* information. You can view this information with this window.
