Cosmic Code Comparison Project or the provenance management system, undertaken at the Los Alamos National Laboratory, aims to address the challenges of managing large-scale simulation and data-intensive projects. The project also aims to establish the robustness of cosmological simulation results for a chosen set of applications relevant to precision near-term observations. Provenance provides an ideal mechanism to reproduce results and also lets scientists to share the experiments and analysis techniques with other domain experts. Visualization of a cosmological data set, such as simulation code's result, convey the data's structure, depending on the input parameters. Useful processing techniques for cosmologists, such as determination of the gravitationally bound objects known as halos, are represented as a series of computational modules.
