Automated Template Testing and Management with GitLab Continuous Integration for AMS Offline Computing

The Alpha Magnetic Spectrometer (AMS) is a detector aboard the International Space Station (ISS) to collect the cosmic ray events from the Universe. It was launched and installed in May 2011 and has been operating continuously since then. Data reconstruction and Monte-Carlo simulation are the two major production activities in AMS offline computing, and templates are defined as a collection of data cards to describe different reconstruction and simulation tasks and to provide necessary input parameters. This paper presents how we use the Continuous Integration mechanism in GitLab to better automate the Monte-Carlo production template testing, including syntax checking, functionality testing, performance testing, and the integration with the existing template management system.
