From Barry’s blog:
This week, in the Los Alamos National Laboratory (LANL) booth at SC06, IBM will demonstrate newly developed interactive ray-tracing technology. The iRT will be running on a hybrid system consisting of four IBM QS20 Cell blades and an AMD Opteron based client. By dynamically balancing work across the four Cell blade’s 1.6 Tflops, the iRT renders high definition images at interactive frame rates using advanced techniques such as BRDF shaders, and ambient occlusion. This mini-Roadrunner is approximately 1/2000th of LANL’s monster 1.6 petaflop system. I hope they invite me back to run the iRT on their finished system.
