+Every structure should divide the information that they store across processors, in order to do this two main approach are considered inside OpenFPM.
+
+* Model decomposition
+* Data driven decomposition
+* Fixed decomposition
+
+The fist approach try to generate a model for the interaction across processors and try to minimize the space
+
+The second instead try to divide the quantity of information the structure store without considering the interactions
+
+## Model decomposition
+
+The modular structure of OpenFPM give the possibility to create distributed structure with different decomposition strategies.
