Abstract
As a network of advanced-era gravitational wave detectors is nearing its design sensitivity, efficient and accurate waveform modeling becomes more and more relevant. Understanding of the nature of the signal being sought can have an order unity effect on the event rates seen in these instruments. The paper provides a description of key elements of the Spectral Einstein Code (SpEC), with details of our spectral adaptive mesh refinement (AMR) algorithm that has been optimized for binary black hole (BBH) evolutions. We expect that the gravitational waveform catalog produced by our code will have a central importance in both the detection and parameter estimation of gravitational waves in these instruments.

We thank Dan Hemberger for providing access to data produced by the head-on BBH simulation used in some of the plots. We thank Jonathan Blackman for providing access to his unequal mass inspiral simulations, as these provided data for most of the plots. We thank Saul Teukolsky, Mark Scheel, Larry Kidder, Harald Pfeiffer and Nicholas Taylor for helpful discussions while designing the AMR code. We thank Abdul Mroue, Tony Chu, Geoffrey Lovelace and Sergei Ossokine for useful feedback on the performance of our AMR algorithm in the context of thousands of BBH simulations. A significant amount of code development was done on the UCSD cluster ccom-boom.used.edu. The Caltech cluster zwicky.cacr.caltech.edu is an essential element of research done with SpEC.
