| 摘 要： | 保留模式并行图形系统在并行性能上有着巨大的潜力。透明、高效的图形对象分布是保留模式并行图形系统的基础。该文提出了一种完整的策略，包括通用的图形对象定义、透明的对象创建和自动一致性维护机制、状态缓存、延时更新、基于消息应答的图像同步输出。该策略实现了自动、高效的图形对象分布，并在高性能集群并行图形系统MSPR中得到了验证。

| Abstract: | Retained-mode parallel graphics systems have great potential in parallel performance.A transparency,effective strategy for graphics objects distribution is the basic of retained-mode parallel graphics system.A systematic solution is presented.It includes the definition of graphics objects,transparency object creation,automatic coherence maintenance,state caching,delayed update and message-based image synchronization.The solution realizes automatic,high-performance graphics object distribution and is tested in MSPR which is high performance parallel rendering system based on cluster. |

| Keywords: | Parallel graphics system Retained-mode Object distribution Delayed update |
