Comparing SpEC and SpECTRE evolutions of the same binary-black-hole initial data

Binary black holes are the most frequent source of gravitational waves, and numerical-relativity models of binary black holes are necessary to learn as much as possible from them. SpECTRE is a next-generation, open-source numerical-relativity code in development that aims to model binary black holes with high accuracy by scaling to more processors than its predecessor, the Spectral Einstein Code (SpEC). In this talk, I will compare evolutions of the same binary black hole initial data with SpECTRE and SpEC, focusing on the evolutions' accuracy and efficiency.
