并行环境下的多通道输出

图像处理通常是采用串行程序，然后使用高性能的图像工作站绘制，图形工作站通过内部的通道在不同屏幕或者同一个屏幕显示，不同通道对应的显示是不一样的。但是这样需要投入很多资金的去购买设备。现在出现了机群技术也称集群技术后，价格便宜的PC机也能做到提供高可靠性、可扩充性和抗灾难性，提供低价高效的高性能环境。如果把程序并行化，然后在集群服务器上计算，最后在对应的屏幕上并行地绘制图片，可以模拟图像工作站的多通道输出。

Multiple Channels Display Based on Parallel Environment

Generally the serial program and high performance workstationare used to process the image.But it need to input a lot of capital.Now have the cluster technology,and the common PC will provide the high abilility,high extensibility and high security for system.And provide the high effect of environment of HPC.If the programs are paralleled,then it is computed in cluster servers,and it is put in screen to process images in parallel.People can simulate the pipeline of workstation by using the common PC.This system gives the new method for process image.
