Parca: A Paramesh-Based Driver for Cactus

The talk will introduce the Parca software, which allows the Paramesh AMR libraries to be used as a Cactus driver thorn. Both Paramesh and Cactus have become fixtures in the numerical relativity community, but until the development of the Parca software Paramesh-based codes were completely incompatible with Cactus-based codes and vice-versa. Preliminary results demonstrating the interoperability of the Parca driver with existing Cactus thorns will be shown.
