Title: Experiences with Infrastructure as Code on HPC systems.
Abstract: A common problem in HPC system administration is managing the software stack, composed by both system and user software. Manual installation and configuration can be error-prone and difficult to scale. An Infrastructure as Code (IaC) approach based on SaltStack is presented, showing the benefits obtained and lessons learned in the process.
