Does setting up a PIC-type DMSWARM with an associated cell DM guarantee that each MPI rank will own the particles with coordinates inside the bounds of the portion of the grid it owns?
There is a caveat that we are currently fixing. Swarm communication is setup to be nearest neighbor (since there is no coarse grid of bounding boxes). So if your particles are initially in the right place, and only move nearest neighbor, everything is fine. We are adding a hierarchy of bounding boxes so that we can communicate anywhere.
