基于InfiniBand的集群分布式并行绘制系统设计

为解决 sort-first型并行绘制负载不均衡和网络拥塞问题，在研究原有体系结构的基础上，提出了一种基于InfiniBand高速网络的PC集群分布式并行图形绘制解决方案。增加了显示节点负责场景显示。使用一种改进型的基于绘制历史的动态负载均衡算法解决了负载不平衡问题；利用InfiniBand消息传输机制开发了同步控制策略，有效地实现了帧同步。实验结果表明，该方案在保存场景一致完整性的基础上，与传统体系结构相比，显著地提高了系统帧率，降低网络通讯消耗。

Design of PCcluster distributed parallel rendering system based on InfiniBand

To solve the imbalance and network congestion problem for sort first parallel rendering system, a new approach for PC cluster distributed parallel rendering under InfiniBand high speed network was proposed. This approach added display nodes to undertake the scene display task. Used a improved dynamic load balancing algorithm based on rendering history to deal with the system's imbalance problem. At the same time this system developed a synchronism control strategy based on the InfiniBand message transfer mechanism. The experiment result shows that the new approach can maintain the scene consistency and integrity, Compare to the original architecture, It can improve the system's frame rate and reduce the network traffic consumption.
