The National Ignition Facility (NIF), the world’s most energetic laser, completed a multi-year project for migrating control software platforms from Ada to Java in 2019. Following that work, a technology refresh of NIF’s Digital Video (DVID) systems was identified as the next important step. The DVIDs were facing long-term maintenance risk due to its obsolete Window XP platform, with over 500 computers to be individually upgraded and patched, 24 camera types with a variety of I/O interfaces and proprietary drivers/software with their licensing needs. In this presentation, we discuss how we leveraged the strengths of NIF’s distributed, cross platform architecture and our system migration expertise to migrate the DVID platforms to diskless clients booting off a single purpose-built immutable Linux image, and replacing proprietary camera drivers with open-source drivers. The in-place upgrades with well-defined fallback strategies ensured minimal impact to the continuous 24/7 shot operations. We will also present our strategy for continuous build, test, and release of the Linux OS image to keep up with future security patches and package upgrades.

The National Ignition Facility (NIF) is the world’s largest 192 laser beam system for Inertial Confinement Fusion (ICF) and High Energy Density Physics (HEDP) experiments. The NIF’s Integrated Computer Control System (ICCS) team conducts quarterly software releases, with two to three patches in between. Each of these software upgrades consists of deployment, regression testing, and a test shot. All of these are done with the team members inside the NIF control room. In addition, the NIF ICCS database team also performs the Database Installation and Verification Procedure dry run before each software upgrade. This is to anticipate any issue that may arise on the day of the release, prepare a solution for it, and make sure that the database part of the upgrade will be completed within the allotted time slot. This talk is about how the NIF ICCS software teams adapted when the LLNL workforce began working remotely due to the COVID-19 pandemic. These adaptations led to a better and more efficient way of conducting the NIF ICCS software upgrades.
