METIS_MESH is a data directory which contains examples of "mesh" files used by the METIS program. METIS can read a mesh file, and partition the elements in a balanced way so that each partition has about the same number of elements, while minimizing the number of cases in which elements from different parts of the partition share an edge or face. This process is designed with the idea that the mesh represents a computation that is to be divided up among various processors, with the stipulation that the amount of interprocessor communication must be limited.
