Using Cactus for Numerical Relativity

Our Numerical Relativity simulations are carried out with the Cactus program. We have summarized the procedure on how to install and compile Cactus programs. You should note that this guide was created based on our experience installing Cactus on our own computers. Although it is general enough, you will have to do your own if something goes wrong, and check the proper documentation at cactus website. One of the advantages Cactus provides is parallelization. The following is a set of notes on installing and running WaveDemo in the Lobizon Cluster.

• Installing Cactus and other utilities
• Running cactus in parallel on two PCs
