Blue Waters could be the key to understanding the connections between Earth’s deep structure and seismic energy. Often one of the major bottlenecks of this sort of research is the large amount of data it can produce. A research team at the University of Wyoming has developed a scalable code to compute this data more efficiently. Liqiang Wang and Po Chen found that no matter the method for running their codes, the input/output (I/O) was too great; just reading and accessing their data became an issue. That is when the team turned to Blue Waters, a sustained petascale powerhouse.
