Two adaptive location policies for global scheduling algorithms

Two location policies that, by adapting to the system load, capture the advantages of receiver-initiated, sender-initiated, and symmetrically initiated algorithms are presented. A key feature of these location policies is that they are general and can be used in conjunction with a broad range of existing transfer policies. By means of simulation, two representative algorithms making use of these adaptive location policies are shown to be stable and to improve performance significantly relative to nonadaptive policies
