Titre français : Partitionnement adaptatif et allocation dynamique for les systèmes à large échelle
Titre anglais : Adaptative Partitionning and Dynamic Allocation for Large Computing Systems
Abstract : Dynamic load balancing and migration are two main mechanisms to increase system throughput and to reduce application response time. These mechanisms become very complex (and time consuming) to manage, when the computing system increases in scale and heterogeneity. We have proposed the Territory Model that separates the system in Computational Domains, where each domains manage its resources by means of Resource Territories, and its application by means of Execution Territories. This paper presents performance evaluations of our model, applied to parallel machines management. The load balancing algorithm associated to each Execution Territory is based on force computation between processes and nodes. Measures are compared with random and diffusion algorithms, and show that our model is efficient, adaptable and scalable with a low system overhead.
Key-words : load balancing, resource management, simulation, forces, territory
