Local Robustness: A Process Migration Criterion in HPC Clusters

Cluster computing systems require managing their resources and running processes dynamically in an efficient manner. Preemptive process migration is such a mechanism that tries to improve the overall performance of a cluster system running independent processes. In this paper, we show that blind migration of processes at runtime by such a mechanism does not lead to better performance. Instead, the preemptive process migration mechanism requires a criterion to determine if the migration of a process would enhance the cluster performance or not. We introduce a criterion called local robustness to guide the mechanism in this respect. The results of our experiments on a real implementation of a mechanism using this criterion have shown improvements to the overall performance of a Mosix cluster in terms of system response time compared to when processes were migrated blindly.
