Benchmarking of parallel ray tracing using different load granularity

This paper examines the efficiency of different load granularity in ray tracing. Benchmarking of image rendering using raytracing algorithm with different load balancing scenarios is presented. Open source Monte Carlo raytracer was modified in order to enable measurement of individual thread execution time. It is showed that, with specific load balancing scenarios, specific threads' idle time can be reduced and thus overall program execution time improved. The presented results are analyzed and future work suggested.
