But because of the uncertainties between the dependencies of the parallel tasks and their communi-cation during the compile-time, researchers are more inclined to study the dynamic load balancing algorithms(DLB).There are almost four kinds of DLB algorithms including the centralized DLB, distributed DLB, global DLB and LocalDLB, all of them have their pros and cons.
