Before specialized graphics-processing chips existed, pioneers in the field of visualization used multicore supercomputers to realize data in three dimensions. Today, however, the speed at which supercomputers can process data is rapidly outstripping the speed at which they can input and output that data. Graphics-processing clusters are becoming obsolete.
Researchers at Argonne National Laboratory and elsewhere are working on a solution. Rather than moving massive datasets to a specialized graphics-processing cluster for rendering, which is how things are done now, they are writing software that allows the thousands of processors in a supercomputer to do the visualization themselves.
