Experimental Scalability Evaluation of Unbalanced-Nodes PC Cluster

When a PC cluster is extended with new nodes, if a good scalability can keep is focused, especially in unbalanced-nodes PC cluster. In this paper, an experimental scalability evaluation of unbalanced- nodes PC cluster is illustrated. The results are also compared with that of balanced-nodes PC cluster. And, on the experiment results, the problems in parallel and distributed processing on unbalanced-nodes PC cluster are discussed and considered.
