OLCF Supercharges Supercomputer Analytics with Apache Kafka

The high-performance computing (HPC) systems at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) are about to vault into the “pubsub” era of real-time streaming analytics. Employing the open-source Apache Kafka event-streaming platform, ORNL’s HPC Core Operations (Ops) Group has built a whole new publish/subscribe system for…

Modeling Every Building in America Starts with Chattanooga

Buildings use 40 percent of America’s primary energy and 75 percent of its electricity, which can jump to 80 percent when a majority of the population is at home using heating or cooling systems and the seasons reach their extremes. The US Department of Energy’s (DOE)’s Building Technologies Office (BTO),…

Can a UNICORN Outrun Earthquakes?

Each year, anywhere from a few hundred to tens of thousands of deaths are attributed to the catastrophic effects of major earthquakes. Apart from ground shaking, earthquake hazards include landslides, dam ruptures, flooding, and worse—if the sea floor is suddenly displaced during an earthquake, it can trigger a deadly tsunami.…

A New Parallel Strategy for Tackling Turbulence on Summit

Turbulence, the state of disorderly fluid motion, is a scientific puzzle of great complexity. Turbulence permeates many applications in science and engineering, including combustion, pollutant transport, weather forecasting, astrophysics, and more. One of the challenges facing scientists who simulate turbulence lies in the wide range of scales they must capture…

In the Mix

by Sara Shoemaker Mixing metals into alloys is an age-old practice. The tedious trial and error of heating, cooling, testing, and remixing was once the only method to fine-tune the best blend of metals for ideal strength and durability. In recent times, computational scientists have developed a faster, more precise…
