Shock Treatment for CFD Simulations

A team of researchers from the Georgia Institute of Technology conducted the largest-ever computational fluid dynamics, or CFD, simulation of high-speed compressible fluid flows. Using the Frontier supercomputer at the Department of Energy’s Oak Ridge National Laboratory, the team applied a new computational technique called information geometric regularization, or IGR.…

Getting the Matrix of Life Right

More than a year ago, computational scientists at the Department of Energy’s Oak Ridge National Laboratory published a study in the Journal of Chemical Theory and Computation that raised a serious question about a long-standing methodology used by researchers who conduct molecular dynamics simulations involving water. What if using the standard…

Speeding Up Chemical Reactions

Using the now-decommissioned Summit supercomputer, researchers at the Department of Energy’s Oak Ridge National Laboratory ran the largest and most accurate molecular dynamics simulations yet of the interface between water and air during a chemical reaction. The simulations have uncovered how water controls such chemical reactions by dynamically coupling with…

Journey to the Center of a Neutron Star

For astrophysicists, neutron stars stand out as objects of irresistible fascination — perhaps, in part, because of how difficult they are to decipher. But calculations conducted on the Frontier supercomputer, located at the Department of Energy’s Oak Ridge National Laboratory, have revealed new clues about the inner workings of neutron…

The OLCF’s Problem Busters

Professor Spencer Bryngelson and his team of researchers at Georgia Tech’s School of Computational Science and Engineering were excited to bring their code into the new world of exascale-class supercomputing. The Multicomponent Flow Code, or MFC, originated in the early 2000s to model the simultaneous movements of gases and liquids as they…

Summit’s Bonus Year of Scientific Achievement

Leadership-class supercomputers dedicated to open science are not built to last forever. In fact, they have a limited lifespan by design. No matter how powerful they may be on launch day, advancements in computing technology and changing computing needs will push them closer to obsolescence with each passing year until…

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…
