Load balancing method based on render history in cluster rendering
基于绘制历史的sort-first集群绘制负载平衡方法

Performance of sort-first cluster parallel rendering system is greatly influenced by load balance. Static load balancing method is poorly adaptive. As to dynamical methods, those based on geometry data traversing are not practical, and those based on coarse geometry data granularity can be put into practice but depend on the pretreatment of geometry data. Therefore, a practical load balancing method based on render history was proposed. This method does not depend on geometry data, but utilizes render time of previous frame and its information of load distribution as the input of load balancing for the next frame's rendering. The method is tested on cluster rendering platform and the test results show that it is very effective.
