Resumen: Some parallel computations, i.e. sparse-matrix factorizations, may be expressed as directed graphs. Once the graphs are obtained, they may be scheduled or mapped to a parallel machine in different ways. This document describes tools developed to experiment with these kind of computations, creating trivial schedulings, and generating MPI programs which simulate their behavior when executed on real machines. The tools have been used to experiment with some sparse-matrix factorization graphs on a Beowulf cluster.
