TL;DR: MOOSE as mentioned in this paper is a parallel computational framework targeted at solving coupled, nonlinear partial di?erential equations often arise in sim- ulation of nuclear processes, which is based on mathematics based on Jacobian-free Newton Krylov (JFNK).

TL;DR: The novel abstractions that have been added to Kokkos version 3 such as hierarchical parallelism, containers, task graphs, and arbitrary-sized atomic operations to prepare for exascale era architectures are described.

TL;DR: The Kokkos EcoSystem as discussed by the authors is a portable software stack based on the Kokkos Core Programming Model, which provides math libraries, interoperability capabilities with Python and Fortran, and Tools for analyzing, debugging, and optimizing applications.

TL;DR: The Exascale Computing Project (ECP) is invested in co-design to assure that key applications are ready for exascale computing as discussed by the authors, and the Co-design Center for Particle Applications (CoPA) is established within ECP.

TL;DR: The Co-design Center for Particle Applications (CoPA) as discussed by the authors is addressing challenges faced by particle-based applications across four sub-motifs: short-range particle-particle interactions (e.g., those which often dominate molecular dynamics (MD) and smoothed particle hydrodynamics (SPH) methods), long-range PIC methods, and linear-scaling electronic structure and quantum molecular dynamics algorithms.
