在计算机集群上，采用Windows 通信基础（WCF）架构，实现大范围DEM数据的并行绘制。根据控制节点的任务分配策略对集群中各服务器进行任务分配；服务端采用WCF的任务并发模式，对控制节点分配的任务直接分发给服务实例，无需放到消息队列中进行等待，以此提高集群对DEM数据的并行绘制效率。通过对不同数据量的DEM数据进行集群的并行绘制测试，得出绘制加速比随着数据量的增加而增加的结论，这对于大数据量的DEM数据的并行处理具有重要意义。

In a computer cluster,using the basic WCF communication architecture,a wide range of DEM data was parallel rendering.According to the task allocation strategy on master node,it was assigned to each server in the cluster;the server used task concurrency model of the WCF;the master node directly distributed tasks to an instance of service which need not put it into the message queue of waiting,to improve the efficiency of parallel rendering of DEM data.Through the different amount of DEM data parallel drawing test on cluster, the rendering acceleration ratio increased with the growing amount of data.For a large amount of data,DEMdata parallel processing had important significance.
