As a parallel programming model, Map-Reduce is used for distributed computing of massive data. Map-Reduce model encapsulates
the details of parallel implementation, fault-tolerant processing, local computing and load balancing, etc., provides a simple but powerful interface. In case of having no clear idea about distributed and parallel programming, this
interface can be utilized to save development time. This paper introduces the method of using Hadoop, the open-source Map-Reduce
software platform, to combine PCs to carry out scalable parallel computing. Our experiment using 12 PCs to compute N-body problem based on Map-Reduce model shows that we can get a 9.8x speedup ratio. This work indicates that the Map-Reduce can be applied in scalable parallel computing. 相似文献
