Abstract
To improve ray casting frame rates on shared memory architectures, the authors explore memory hierarchy effects and their interaction with parallel partitioning and load balancing. With their optimizations, a 16-processor Power Challenge machine renders a 1-Gbyte data set at a frame per second-faster than previously reported for a data set this large
