PEPC - a Scalable Multi-Physics O(N) Tree Code

Long-ranged interactions play an important role in many application domains using particle-based computational modelling.We present PEPC, a tree code developed at JSC that acceleratesthe computation of various forms of long-ranged interactions includingelectrostatics, Newtonian gravity, vortex dynamics, and smoothed particle hydrodynamics.PEPC implements optimised forms of both the classic Barnes Hut tree code algorithm and Dual-Tree Traversal showing scalabilty across 458 752 cores of JUQUEEN
