sci@gentoo.org Gentoo Science Project ParMETIS is an MPI-based parallel library that implements a variety of algorithms for partitioning unstructured graphs 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. Build the 64 bits integer library (needed for > 2^31 vertices) Floating-point operation done as double precision
