Abstract

The grid enables large-scale aggregation and sharing of computational resources. In this paper, we introduce a method for solving the N-body problem on a cluster-grid using our grid system, ALiCE (Adaptive and scaLable internet-based Computing Engine). The modified Barnes-Hut algorithm allows the N-body problem to be solved adaptively using compute resources on-demand. The N-body program is written using ALiCE object programming template. Our experiments varying the number of bodies per task and the number of computation nodes demonstrate the feasibility of exploiting parallelism on a grid system.
