What is it about?
Our library makes it easy to create distributed and parallel simulations where the simulation space is divided into discrete "cells" through which "particles" may travel over time. For instance, in molecular dynamics, molecules move in the simulation space due to the force interactions between them. Our library makes it easy to express how particles interact with each other and automatically schedules the necessary communications between cells located on different hosts.

Why is it important?
Our technique allows the library to break down the traditional all-to-all communication phase into many 1-to-1 overlapping communications, improving performance at relatively low effort for the programmer.
