Particle-based simulations are ubiquitous throughout many fields of computational science and engineering, spanning the atomistic level with molecular dynamics (MD), to mesoscale particle-in-cell (PIC) for solid mechanics, device-scale modeling PIC methods plasma physics, massive N-body cosmology galaxy structures, other in between (Hockney & Eastwood, 1989).While these use particles represent significantly different entities completely physical models, low-level details shared including performant algorithms short-and/or long-range particle interactions, multi-node communication patterns, data management tasks such as sorting neighbor list construction.
