Mondriaan version 2.0, software for sparse matrix partitioning

Mondriaan is a sequential program written in C that can be used to partition a rectangular sparse matrix, an input vector, and an output vector for parallel sparse matrix-vector multiplication. The program is based on a recursive bipartitioning algorithm that cuts the matrix horizontally and vertically, in a manner resembling some of the famous Mondriaan paintings. The algorithm is multilevel, hypergraph-based, and two-dimensional. It reduces the amount of communication and it spreads both computation and communication evenly over the processors. The program can partition hypergraphs with integer vertex weights and uniform hyperedge costs, but it is primarily intended as a matrix partioner.",
