In 2016, the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) announced two unambiguous detections of gravitational waves from merging binary black holes. The search for binary neutron star and black hole mergers uses match filtering to correlate Advanced LIGO data with a bank of templates to search for gravitational waves from mergers with a total mass from 2 to 100 solar masses. Noise in the LIGO detectors is neither stationary nor Gaussian and so additional signal processing is required to separate signals from noise. The detection search is written as a parallelizable workflow that can run on the Open Science Grid distributed computing network. I will discuss the search for compact-object mergers in Advanced LIGO data and the computing challenges of Advanced LIGO's search for gravitational waves.
