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…

Exascale Acceleration

Just how fast can the world’s fastest supercomputer go? Maybe even faster than imagined. Researchers studying plasma physics for particle accelerators recently used the Oak Ridge Leadership Computing Facility’s Frontier supercomputer to achieve a speedup by as much as eightfold in their code’s performance – more than double the improvement…

Distilling How Water Turns into Ice

Among the mysteries of science that continue to elude researchers, one stands apart in its vexing simplicity: ice. Yes, frozen water. Water’s transformation from liquid to solid is actually a complex process of nature that scientists have named—nucleation—yet do not fully understand. However, Princeton University researchers have taken trailblazing steps…

Solving the Protein Puzzle

A simple scoop of soil or water can hold an entire ecosystem–potentially millions or more microscopic organisms and the countless proteins they rely on to survive. Computations performed at the U.S. Department of Energy’s Oak Ridge National Laboratory could help count, sort and catalog each of those proteins in record…
