Abstract: Abstract Cell dynamics simulation is a very promising approach to model dynamic processes in block copolymer systems at the mesoscale level. A parallel algorithm for large-scale simulation is described in detail. Several performance tuning methods based on SGI Altix are introduced. With the efficient strategy of domain decomposition and the fast method of neighboring points location, we greatly reduce the calculating and communicating cost and successfully perform simulations of large-scale systems with up to 5123 grids. The algorithm is implemented on 32 processors with the speedup of 28.4 and the efficiency of 88.9%.
