+Every structure should divide the information that they store across processors, considering that in our context multiple distributed structures can interact with each other and dynamically change, our particular focus is in mapping structures into common domain and decomposition and distribution strategies over this domain. Once this domain is defined two main approach are considered inside OpenFPM.
