Title: Dynamic Data Management for Parallel Ray Tracing
Authors: Boris Farizon and Alon Itai
PDFNot Available
Abstract: A parallel implementation of Ray Tracing is described. Alternative implementation choices are examined: organizing local and global memory, paging policies, task allocation, task granularity, and scanning order. These issues are discussed both analytically and experimentally. Extensive experiments were conducted to compare between different methods, and determine the best choice of parameters. The foremost conclusion is that in our parallel implementation, communication is the bottleneck, and that increasing the amount of memory reduces the communication.
