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…

Exascale’s New Frontier: ADIOS

PI: Scott Klasky, Oak Ridge National Laboratory In 2016, the Department of Energy’s Exascale Computing Project (ECP) set out to develop advanced software for the arrival of exascale-class supercomputers capable of a quintillion (1018) or more calculations per second. That leap meant rethinking, reinventing, and optimizing dozens of scientific applications…

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…

Investigating the Earth’s Inner Workings

Princeton's Jeroen Tromp is part of a team using Oak Ridge National Laboratory’s (ORNL’s) Titan supercomputer, to reveal the Earth’s inner workings via adjoint tomography simulations, or monitoring the interaction of a forward wavefield, in which the waves travel from the source to the receivers, and an “adjoint” wavefield in…
