Exascale’s New Frontier: ExaWind

PI: Michael Sprague, National Renewable Energy Laboratory In 2016, the Department of Energy’s (DOE’s) Exascale Computing Project (ECP) set out to prepare advanced software for the arrival of exascale-class supercomputers capable of 1 quintillion or more calculations per second. That meant rethinking, reinventing and optimizing dozens of scientific applications and…

Exascale’s New Frontier: E3SM-MMF

PI: Mark Taylor, Sandia National Laboratories 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 meant rethinking, reinventing, and optimizing dozens of scientific applications and software…

Custom Software Speeds Up, Stabilizes High-Profile Ocean Model

On the beach, ocean waves provide soothing white noise. But in scientific laboratories, they play a key role in weather forecasting and climate research. Along with the atmosphere, the ocean is typically one of the largest and most computationally demanding components of Earth system models like the Department of Energy’s Energy Exascale…

Summit Study Fathoms Troubled Waters of Ocean Turbulence

Simulations performed on the Summit supercomputer at the Department of Energy’s Oak Ridge National Laboratory revealed new insights into the role of turbulence in mixing fluids and could open new possibilities for projecting climate change and studying fluid dynamics. The study, published in the Journal of Turbulence, used Summit to…

The Climate in a Container

Successfully running a simulation program on a supercomputer requires more than just writing code. An application such as a climate model requires libraries, network support, and the correct operating environment. Because of these complex and multilayered requirements, applications are typically customized and built natively on a computing system, making them…

A Data-Driven Journey to the Center of the Earth

In a farewell nod to Titan, scheduled to be decommissioned in August 2019, we present a short series of features highlighting some of Titan’s impactful contributions to scientific research. In Jules Verne’s Journey to the Center of the Earth, an impatient geology professor leads a subterranean expedition in search of…

A Seismic Mapping Milestone

Because of Earth’s layered composition, scientists have often compared the basic arrangement of its interior to that of an onion. There’s the familiar thin crust of continents and ocean floors; the thick mantle of hot, semisolid rock; the molten metal outer core; and the solid iron inner core. But unlike…
