WebOpenMP does not guarantee that a single per-process intra-op thread pool is going to be used in the application. On the contrary, two different application or inter-op threads may use different OpenMP thread pools for intra-op work. This might result in a large number of threads used by the application. Weblarge array-based applications. OpenMP is intended to support programs that will execute correctly both as parallel programs (multiple threads of execution and a full OpenMP support library) and as sequential programs (directives ignored and a simple OpenMP stubs library).

Each thread then determines which of these initial partial tours it should get and pushes its tours onto its local stack. Certainly MPI process 0 can also generate a list of comm_sz partial tours.
