Ken Olum, Jose Blanco-Pillado and Ben Shlaer are using the cluster to attempt to solve an important question in cosmology, namely "How big are cosmic string loops?" Cosmic strings are ultra-thin fast moving filaments hypothesized to be winding throughout the universe, most of it in the form of long loops. There has been much theoretical interest and work in cosmic strings, but before they can connect the theory to future observations, they need to know the typical sizes of the loops the network produces. It turns out this is an ideal question to solve numerically, since the evolution of each individual string segment is easy to compute, and the tremendous scales over which the network evolves makes analytic work extremely difficult. What makes this exciting now is that the previous generation of numerical cosmic string simulations disagreed on what the right answer is. This group believes that current hardware is sufficient to enable them to answer the question definitively.
