Projects

ExaStar

ExaStar is a collaboration between Berkeley Lab, Oak Ridge Lab, Argonne Lab, and Stony Brook University, and is an application development project within the DOE Exascale Computing Project.

Chimera

CHIMERA is our multi-dimensional core-collapse supernova code, capable of tracking the evolution of these systems from the pre-collapse stellar stage to up to a second of evolution time after the core bounce.

TEAMS

Toward Exascale Astrophysics of Mergers and Supernovae: This SciDAC project aims to study the sites of R-process nucleosynthesis using realistic simualtions of core-collapse supernovae and neutron star mergers.

CAAR

A collaborative effort of application development teams and staff from the OLCF Scientific Computing group, CAAR is focused on redesigning, porting, and optimizing application codes for Summit’s hybrid CPU–GPU architecture.
