Over at NICS, Scott Gibson writes that researchers are using XSEDE resources to build the most ambitious simulation of galaxy formation ever attempted.

Georg Hager Interview on the Parallel Universe Computing Challenge


Mike Bernhardt interviews Georg Hager, Captain of last year’s winning Team from Germany in the Intel Parallel Universe Computing Challenge (PUCC) at SC13.

Video: Combining Performance and Portability


“The Argonne Training Program on Extreme-Scale Computing (ATPESC) provides intensive hands-on training on the key skills, approaches, and tools to design, implement, and execute computational science and engineering applications on current high-end computing systems and the leadership-class computing systems of the future. As a bridge to that future, this two-week program fills the gap that exists in the training computational scientists typically receive through formal education or other shorter courses.”

Studying the Cosmic Dark Ages with Petascale Supercomputing


“All of these problems require simulations with extremely high dynamic range in space and time, complex physics (including radiation transport and non-equilibrium gas chemistry), and large simulation volumes. We use the Enzo code (, which has been modified to scale to large core counts on Blue Waters, which is the only machine available where the heavy data and communication needs can be satisfied.”
