In this paper, a tool for predicting and visualizing the performance of iterative methods is presented. These codes come from an exhaustive parallel library of sparse iterative methods and preconditioners in HPF and MPI, developed in a previous work. The tool can be used, both by users and by library developers, to optimize the efficiency of the codes, as well as to simplify their use. The information offered by this tool combines theoretical features of the methods and preconditioners, in addition to certain practical considerations and predictions about aspects of the performance of their execution in distributed memory multiprocessors.
