%description
ParMETIS 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. ParMETIS extends the functionality
provided by METIS and includes routines that are especially suited for parallel
AMR computations and large scale numerical simulations. The algorithms
implemented in ParMETIS are based on the parallel multilevel k-way
graph-partitioning, adaptive repartitioning, and parallel multi-constrained
partitioning schemes developed in our lab.
