Coury Turczyn

Coury Turczyn writes communications content for the Oak Ridge Leadership Computing Facility (OLCF). He has worked in different communications fields over the years, though much of his career has been devoted to local journalism. He helped create Knoxville’s alternative news weekly, Metro Pulse, in 1991 and served as its managing editor for nine years; he returned to the paper in 2006 as its editor-in-chief, until its closure in 2014. Several months later, he and two other former Metro Pulse editors dared to start a new weekly paper, the Knoxville Mercury, based on a hybrid nonprofit ownership model. In between his journalism stints, Coury worked as a web content editor for CNET.com, the G4 cable TV network, and HGTV.com.

New Clues to Improving Fusion Confinement

Nuclear fusion — when two nuclei combine to form a new nucleus, thereby releasing energy — may be the clean, reliable, limitless power source of the future. But first, scientists must learn how to control its production. Building on decades of prior research, scientists have developed sophisticated techniques to improve…

Something in the Water Does Not Compute

Computational scientists at the Department of Energy’s Oak Ridge National Laboratory have published a study in the Journal of Chemical Theory and Computation that questions a long-accepted factor in simulating the molecular dynamics of water: the 2 femtosecond (one quadrillionth of a second) time step. The femtosecond is a timescale…

Adaptable IO System Delivers the Data

Amid the challenges that the Department of Energy’s Oak Ridge Leadership Computing Facility faced in assembling and launching the world’s first exascale-class (more than a quintillion calculations per second) supercomputer, Frontier, one key component was hitch-free. Integral to Frontier’s functionality is its ability to store the vast amounts of data…
