Towards Exascale Astrophysics of Mergers and Supernovae (TEAMS)

The TEAMS project seeks to develop improved simulations of supernovae explosions and neutron-star mergers, with the aim of predicting signatures of these events and advancing scientific understanding of the creation of the heaviest elements. The research will provide models to support and guide the experimental efforts at the Facility for Rare Isotope Beams and similar facilities.

Achieving these goals requires software capable of effectively exploiting current and future architectures. Thus, the computational goal of this proposal is to build a toolkit that can be used on petascale (and eventually exascale) computational architectures to provide world-leading models for the astrophysical sites involved. Our plan is to compare implementations and levels of approximation across a suite of codes that are already in production on leadership-class systems, while building a standard set of microphysics and introducing a consistent framework for code testing. This plan involves considerable development in computational science, both in new algorithms and in refactoring existing algorithms to take advantage of new hardware designs.

The project involves researchers from four national laboratories (ANL. LANL, LBNL, ORNL) and ten universities.
