Rethinking a Century of Fluid Flows

In 1922, English meteorologist Lewis Fry Richardson published Weather Prediction by Numerical Analysis. This influential work included a few pages devoted to a phenomenological model that described the way that multiple fluids (gases and liquids) flow through a porous-medium system and how the model could be used in weather prediction.…

Summit by the Numbers

Download the high-resolution file. The US Department of Energy’s Summit supercomputer located at Oak Ridge National Laboratory enables scientists to simulate complex physical systems and make predictions critical to advancing research and development. Summit’s “smart” architecture merges GPU acceleration and dense local memory to support expanding applications in data science…

OLCF Postdoc Fuses the Gap Between Experiment and Computation

Ada Sedova, a postdoctoral research associate at the Oak Ridge Leadership Computing Facility (OLCF), develops computational calculations for supercomputing codes. In front of the OLCF’s Titan supercomputer, Sedova displays a spectrum from her experimental work, measuring the vibrational frequency of nucleobases (bases of DNA and RNA) at the Spallation Neutron…

A Helping Hand

For many researchers, Titan is only part of the picture; managing and understanding data are quickly becoming as important as the simulations that create it.

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…
