%description
METIS is a set of serial programs for partitioning graphs, 
partitioning finite element meshes, and producing fill reducing 
orderings for sparse matrices. 
The algorithms implemented in METIS are based on the multilevel 
recursive-bisection, multilevel k-way, and multi-constraint 
partitioning schemes developed in our lab.
METIS is distributed with OpenMP support.
