Analysis of molecular dynamics simulations typically involves calculations of based upon atoms which are spatially close to each other. For example a radial distribution function is often only interesting up to distances of around 1.6 nm. The naive approach to calculate this is to calculate the distance between each pair of atoms, however as the size of the system grows the number of useful pair distances decreases while the computational cost scales as N^2.
To greatly improve the efficiency of this operation, we can first decompose the total simulation volume into smaller cells. We can then calculate the distances between atom pairs in neighbouring cells. If atoms are not in neighbouring cells we already know that the distance is to large to be interesting. A theoretical description of this algorithm can be found in this book Appendix F
One domain decomposition algorithm is cell grids.
In this project you would integrate the cell grid algorithm into MDAnalysis.
