Managing Space-Time Heterogeneity for Parallel Structured Adaptive Applications

Free registration required

Executive Summary

Structured Adaptive Mesh Refinement (SAMR) techniques provide an effective means for dynamically concentrating computational effort and resources to appropriate regions in the application domain. However, due to their dynamism and space-time heterogeneity, scalable parallel implementation of SAMR applications remains a challenge. This paper investigates hybrid runtime management strategies and presents an Adaptive Hierarchical Multi-Partitioner (AHMP) framework. AHMP dynamically applies multiple partitioners to different regions of the domain, in a hierarchical manner, to match the local requirements of the regions.
