Comparative study of real-time graphics architectures The graphics industry is undergoing dramatic changes. A variety of new graphics pipeline topologies are now emerging, converging between GPUs and multicore-based graphics processors, both leaning on high parallelism and increasing flexibility. The GPUs, based on hardware graphics pipeline, are becoming more flexible by increased programmability, precision and performance, having improved load balance by hundreds of unified shaders, and new geometry and stream-output stages. The many-core graphics architecture, based on a software rendering pipeline of tens of X86 cores, greatly increases the flexibility and programmability of the architecture as compared to standard GPUs, suggesting an appropriate platform for real-time graphics, and other applications as well (e.g. ray tracing). The presentation will compare the above architectures, and discuss the convergence trends between GPU and Many-Core architectures for real-time graphics, referring to the Stanford GRAMPS programming model for advanced rendering pipelines. Short Bio: Dr. Reuven Bakalash is a founder and a CTO of Lucid Technology Ltd., Israel, a parallel graphics company, developing silicon and software for multiple-GPU high-performance graphics systems. He has been also the founder of HyperRoll Inc., a provider of acceleration software for Business Intelligence and Decision Support Systems (Mountain View, CA.), and of Terra Computers Ltd., Israel, vendor of application oriented parallel supercomputers. Bakalash has filed over 60 patents for Algorithms, Systems and Architectures of 3D Computer Graphics, Volume Visualization, and Analytical Data Bases. He received his Ph.D. from Computer Science Dept. at Ben-Gurion University. He holds M.Sc. and B.Sc. degrees from Ben-Gurion University and the Technion, respectively. Before joining the industry he taught and researched in CS and EE departments at Stony Brook, Hofstra, and Ben-Gurion Universities. He is also an Adjunct Professor at School of Management of Ben-Gurion University
