The top supercomputers typically have aggregate memories in excess of 100 TB, with simulations running on these systems producing datasets of comparable size. The size of these datasets and the speed with which they are produced define the minimum performance that modern analysis and visualization must achieve. We report on interactive visualizations of large simulations performed on Kraken at the National Institute for Computational Sciences using the parallel cosmology code Enzo, with grid sizes ranging from 10243 to 64003. In addition to the asynchronous rendering of over 570 timesteps of a 40963 simulation (150 TB in total), we developed the ability to stream the rendering result to multi-panel display walls, with full interactive control of the renderer(s).
