WebIn the Pthreads and OpenMP implementations, thread 0 uses breadth-first search to search the tree until there are at least thread_count partial tours. 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.
