Abstract

In this paper, several efficient migration and allocation strategies have been compared on the mesh-based multiprocessor systems. The traditional non-preemptive submesh allocation strategies consist of two row boundary (TRB) and two column boundary (TCB). The existing migration mechanisms are online dynamic compaction-four corner (ODC-FC), limited top-down compaction (LTDC), TCB, and the combination of TCB and ODC-FC algorithms. Indeed, the new allocation method is presented in this paper. This mechanism has the benefits of two efficient traditional allocation algorithms. It is the combination of the TCB and TRB allocation methods. Also, in this process the impact of four key metrics on online mapping is considered. The parameters are average task execution time (ATET), average task system utilization (ATSU), average task waiting time (ATWT), and average task response time (ATRT). Using TCB and TRB mechanism with the migration strategies is shown that the new algorithm has better ATET, ATRT, ATWT, and ATSU. It has, respectively, 23.5494, 97.1216, 39.1291, and 4.142% improvements in comparison with the previous mechanisms.
