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.

WebThe NSLOTS variable which is required to set the total number of slots/cores for the parallel environment -pe mpi is usually the number of MPI tasks multiplied by the number of OpenMP threads per task.
