Supercomputers and High Performance Computing (HPC) clusters are not so exotic as people imagine these days. They give companies the power of computation like no one server can give alone. They make new drugs and materials discoveries, universe modeling and AI training, crash simulations and market research possible - all thanks to HPC clusters. Building or renting a HPC cluster is not so difficult either as cloud providers can give you resources to build one cheap and performative enough to use yourself, so If you are or want to become HPC cluster Sysadmin or manager, this book is for you.Supercomputers for Linux SysAdmins delves into the world of modern HPC cluster architecture, hardware, software and resources management using a Linux/UNIX based approach. The number of HPC clusters is growing with an estimated 30 billion by 2030 but there are not enough sysadmins to run and manage them, this book serves to bridge this gap to help more Sysadmins and managers to transition into the exiting world of HPCs. This book helps those with a strong foundational knowledge in Linux, to deal with supercomputers and HPC clusters. We start with the basic principles of supercomputer management, fundamentals of Linux and UNIX, Shell Scripting and systemd and well as other open source tools and frameworks, taking you thorough the security, monitoring and hardware requirements for supercomputers and HPC clusters.You Will Learn:How to plan new supercomputersThe main principles and technologies used in supercomputers and HPC clustersHow to set up the software environments on new supercomputers To set up supercomputer and HPC cluster resources and jobs managementTo manage accounts, resource sharing and many more.Who is it for: The main audience of this book are regular UNIX/Linux sysadmins and managers, who should deal with HPC clusters on-prem or in cloud and those who are interested in supercomputers and HPC clusters and how to utilize them in their projects and teams.
