The SoLid experiment aims to measure short distance neutrino oscillations using nuclear reactor antineutrinos. Key to its sensitivity are the experiment's high spatial and energy resolution, accomplishable via detector segmentation, large data rates and sophisticated reconstruction algorithms. SoLid is also capable of tracking cosmic muons; in principle a source of background, these turn into a valuable calibration source if they can be cleanly resolved. This talk gives an overview of the SoLid experiment, focusing on the associated computational challenges, and presents a brief selection of results from cosmic ray reconstruction at the most recent SoLid prototype, installed in the SCK-CEN research nuclear reactor at Mol, Belgium
