Jean Zay: The ParMETIS library
Introduction
ParMETIS is an MPI-based parallel library which implements a variety of algorithms for partitioning unstructured graphs, meshes, and for computing fill-reducing orderings of sparse matrices.
Installed versions
The ParMETIS library offers several variants depending on the compiler and the graph representation size for the type of data. In general, the 32-bit version will be sufficient for most projects. The 64-bit version must be used if the total number of graph nodes or edges to be partitioned surpasses the representation on 32 bits, or 2^31-1.
