Dynamic load-balancing, i.e. re-partitioning simulation environments at run-time, becomes essential when the load in the partitions change. In decentralised distributed simulation the information needed to dynamically load-balance seems difficult to collect and to our knowledge, all solutions apply a local dynamic load balancing: partitions exchange load only with their neighbours (more loaded partitions to less loaded ones). This limits the effect of the load-balancing. In this paper, we present a global dynamic load-balancing of decentralised distributed simulations. Our algorithm collects information in a decentralised fashion and makes re-balancing decisions based on the load processed by every logical processes. While our algorithm has similar results to others in most cases, we show an improvement of the load-balancing up to 30% in some challenging scenarios against only 12.5% for a local dynamic load-balancing.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||Institute of Electrical and Electronic Engineers (IEEE)||Copyright (published version):||2014 IEEE||Keywords:||Load balancing; Behaviour simulation; Dynamic partitioning||DOI:||10.1109/WSC.2014.7020207||Language:||en||Status of Item:||Peer reviewed||Conference Details:||2014 Winter Simulation Conference (WSC), Savanah, Georgia, USA, 7 - 10 December, 2014|
