1. Illuminator Distributed Visualization Library Demo This little library provides contour surface viewing for PETSc's 3-D distributed array objects using the Geomview viewer. This package contains a demonstration program "chts" (Cahn-Hilliard timestep). With mpich, you can run it in parallel using "mpirun -np X /usr/bin/chts" where X is the number of processes (optimally equal to the number of processors), as long as process 0 has access to your X display.
