4. In 1930, John Vincent Atanasoff has had a problem leading to the
extremely large-scale system of 30 linear algebraic equations arising from
application of Ritz method for discretization of differential equations.
This has been the motivation to invent the computer.
µ-FEM analysis of bone microstructure
High Performance Computing (HPC) is one of the most rapidly developing
part of computational sciences.
The advanced HPC applications reach billions of degrees of freedom.

29. Unstructured meshes
Figure: 3D FEM discretization: unstructured mesh and and ParMETIS partitioning for 16 processors
ParMETIS is developed by Karypis Lab. It is an MPI-based parallel library that
implements a variety of algorithms for partitioning unstructured graphs,
meshes, and for computing fill-reducing orderings of sparse matrices.

30. ParMETIS partitioning
Table: 3D FEM discretization: unstructured mesh and and ParMETIS partitioning for 512 processors
ParMETIS computes in parallel partitionings of very large unstructured
meshes.
A high quality balance with respect to the number of elements and
vertices, and minimization of the size of interfaces is provided.
The relatively large number of neighbors is still an open problem.
