Using Multi-threading for the Automatic Load Balancing of 2D Adaptive Finite Element Meshes
In this paper, we preseilt a multithreaded approach for the automatic load balmlcing of adaptive finite element (FE) meshes. The platform of our choice is the EARTH multithreaded system which offers sufficient capabilities to tackle this problem. We implement the adaption phase of FE applications on trimlgular m_hes, azld exploit the EARTH token mechaafism to automatically balance the resulting irregular a_ld highly nonuniform workload. We discu_ the results of our experiments on EARTH-SP2, an implementation of EARTH on the IBM SP2, with different load balancing strategies that are built into the runtime s)_tem.
