Clusters built from single-core systems are cost-effective as for the performance improvement and availability. However, the hardware constraints put limitations on the performance of single-core systems. Hence, it is difficult to meet with the increasing high performance requirements of diversified applications at different levels for general purpose computing. A promising feasible solution is the novice multi-core systems which extend the parallelism to CPU level by integrating multiple processing units on a single die. This paper uses Finite-Difference Time-Domain (FDTD) algorithm as a case study, designing suitable parallel FDTD algorithms for three architectures: distributed-memory machines with single-core processors, shared-memory machines with dual-core processors, and the Cell Broadband Engine (Cell/B.E.) processor with nine heterogeneous cores. The experiment results show that the Cell/B.E. processor using 8 SPEs achieves a significant speedups of 7.05 faster than AMD single-core Opteron processor and 3.37 than AMD dual-core Opeteron processor at the processor level.
