An N-Body simulation is a simulation of a dynamic system of particles that are under the influence of physical forces, such as gravity or magnetism. It is mostly used in astrophysics to study the processes involving nonlinear structure formation, such as the formation of galaxies, planets, and suns. They are also used to study the evolution of the large-scale structure of the universe, including estimating the dynamics of a few body systems such as the earth, moon, and sun.
Now, N-body simulations require a lot of computational resources. For example, a 10-body system has 10*9 forces that need to be computed at the same time. You can see that, if we increase the number of particles, the number of forces increases exponentially. So a 100-body system will require 9,900 forces to be calculated simultaneously. That is why N-Body simulations are generally run on powerful computers. However, we are going to use our Raspberry Pi cluster to accomplish this task because...
