对于建筑中的照明模拟，需要正确计算虚拟场景的照度。Radiance合成成像系统为这一问题提供了出色的解决方案。不幸的是，模拟复杂的场景导致长的计算时间，即使是一帧。本文提出了一种适用于中高复杂度场景的并行化策略，以减少计算时间。对于一组场景，所获得的加速比表明所选择的负载平衡方法的良好性能。MPI的使用为工作站集群（CoW）以及共享内存多处理器（SMP）提供了一个独立于平台的解决方案。
For lighting simulations in architecture there is the need for correct illumination calculation of virtual scenes. The Radiance Synthetic Imaging System delivers an excellent solution to that problem. Unfortunately, simulating complex scenes leads to long computation times even for one frame. This paper proposes a parallelization strategy which is suited for scenes with medium to high complexity to decrease calculation time. For a set of scenes the obtained speedup indicates the good performance of the chosen load balancing method. The use of MPI delivers a platform independent solution for clusters of workstations (CoWs) as well as for shared-memory multiprocessors (SMPs).
