摘要： Disclosed are a method of and system for creating a load balanced spatial partitioning of a structured, diffusing system of particles with pairwise interactions that is scalable to a very large number of nodes and has favorable communications characteristics including well defined bounds on the number of hops and the number of nodes to which a particle's position must be sent. To deal with structural imbalance, we can assign a weight corresponding to the computational cost for a particular pair interaction of particles or locally clustered groups of particles to simulation space at the midpoint of the distance between the particles or centers of the clusters. We then carry out a spatial partitioning of the simulation volume using a k-d tree or optimal recursive bisection (ORB) to divide the volume into sections that have approximately equal total weights. To deal with local degradation of the load balance caused by changes in the distribution of particles from that used to determine the original spatial decomposition one can assign the actual computation of the pair interaction between two particles to any node that has the positions of both particles.
