hpc clusters

HPC clusters are custom-built supercomputers that overwhelmingly run Linux because it offers the control, flexibility, and scalability needed for exotic processors, accelerators, interconnects, schedulers, and storage. The tag covers discussions about why Linux dominates high-performance computing, focusing on the ability to inspect, strip down, rebuild, and tune the operating system for enormous scale. Topics include the strategic advantages of Linux over Windows or macOS in HPC environments, the importance of customizability, and the role of open-source software in achieving peak performance. This tag is relevant for IT professionals, researchers, and system administrators interested in the architecture and OS choices behind modern supercomputing clusters.
