Immunological Approaches to Load Balancing in MIMD Systems
share
Effective utilization of Multiple-Instruction-Multiple-Data (MIMD) parallel computers requires the application of good load balancing techniques. In this paper we show that heuristics derived from observation of complex natural systems, such as the mammalian immune system, can lead to effective load balancing strategies. In particular, the immune system processes of regulation, suppression, tolerance, and memory are seen to be powerful load balancing mechanisms. We provide a detailed example of our approach applied to parallelization of an image processing task, that of extracting the circuit design from the images of the layers of a CMOS integrated circuit. The results of this experiment show that good speedup characteristics can be obtained when using immune system derived load balancing strategies.
