HPC
High-performance computing (HPC) refers to tightly integrated compute, storage, and networking infrastructure designed for large-scale scientific and technical workloads.
In climate and Earth-system modeling, HPC environments are used to run numerically intensive simulations, post-process high-volume outputs, and execute ensemble experiments with strict runtime constraints.
Effective HPC operations combine scheduler-aware workflows, parallel storage architecture, reproducible software environments, and a lot of careful Linux systems work.
Why it matters
HPC is one of the places where programming, data engineering, infrastructure design, and system administration stop being separate interests. Storage layout, job design, file formats, network quality, and automation all shape whether scientific work is actually possible at scale.
