In our work we improve the EPPI programming environment, which was made in the University of Castilla - la Mancha one year ago. EPPI is a tool for simulating parallel algorithms that runs on a monoprocessor standar computer under the Unix operating system, what makes it easily transportable. This environment provides a set of tools oriented to digital image processing, whereby it is very adequate for performance stidies of parallel architectures and algorithms. Although it was first built to sumulate NETRA architecture [I], it can now admit different topologies, shared/distributed memory configurations and a variable number of processors with floating point capacity and several simulation parameters, providing also information about execution of the algorithm, allowing capacities of debugging and optimization. In this paper, our shows the tool EPPI with a comparison module which allow to compare different architectures and algorithms.
