Got a minute? Building software at the LHC

Analyzing data from the Large Hadron Collider is challenging. Around 3,000 scientists work on the problem, which means that there are 3,000 people contributing software. With such a large group, it is paramount that the code be tested to ensure that a new contribution doesn’t cause the rest of the program to malfunction. Scientist Sam Hewamanage shows how the code is checked. View the video. Video: U.S. CMS
