Abstract Scope |
Peridynamics is a nonlocal reformulation of classical continuum mechanics ideal for simulation of material failure and damage, successfully demonstrated as a tool capable of capturing complex fracture phenomena across many applications. However, the nonlocal nature of peridynamics makes it highly computationally expensive compared to classical continuum mechanics, hindering large-scale fracture simulations. We present CabanaPD, a new performance portable and exascale-capable peridynamics application designed to run on U.S. Department of Energy supercomputers by building on top of the Cabana and Kokkos libraries. We will discuss design of CabanaPD, highlighting the performance critical force and communication kernels, explore performance across particle counts and neighborhood sizes, and show scalability for benchmark test problems. |
