Welcome to ASCR Discovery, a webzine about the research
that powers computational science – the use
of computers to gain insight and understanding of scientific
The Office of Advanced Scientific Computing Research in the Department of Energy Office of Science supports the projects described here. ASCR’s portfolio includes projects at DOE laboratories and many public and private universities. Such research may take years to reach fruition, but has profound impact on science and, ultimately, the way we live.
We hope you find ASCR Discovery enlightening, and we encourage your comments.
Careers that compute
A Department of Energy advisory
committee’s report cites
numerous obstacles and offers
several cures for a dearth of applicants
for advanced scientific computing jobs.
Exascale computing will demand machines that can divvy up tasks a billion ways to get the right data to the right processor at the right time. A project called ROSE is showing the way.
Nuclei by the
Oak Ridge National Laboratory researchers are using supercomputers to calculate the universe’s nuclear forces and atomic features from scratch.
Mathematicians and spouses Antoine Cerfon and Miranda Holmes-Cerfon work in fusion energy and self-assembling materials, respectively, earning each an Early Career Research Program award.
Pacific Northwest National Laboratory modelers turn to extreme-scale computing to simulate climate and weather extremes like the ‘Pineapple Express’ that drenched the
West Coast this winter.
Checking it out
PETSc, a library of ready-to-use high-performance computing software, is being used worldwide as a key player in creating simulations for a panoply of phenomena. The software will receive special recognition at a major scientific computing meeting in March.

Exascale road bumps
Myriad technical challenges block the path to a computer a thousand times faster than today’s machines. A Department of Energy committee identifies the top 10.
