HPC cluster: definition

An HPC cluster (high performance computing cluster) is a group of several powerful computers, known as nodes, that are connected to each other via a high-speed network. These computers work in parallel on complex tasks and deliver enormous computing power that goes far beyond that of a single computer.

• Parallel computing: Tasks are split into subtasks and processed simultaneously.
• Scalable structure: Additional computers can be added to increase performance.
• Central management: A job management system controls when and how tasks are distributed across the nodes.
• High speed: Ideal for compute-intensive processes such as simulations, data analysis or AI training.

• Scientific simulations (e.g. weather, fluid dynamics, particle physics)
• Medical research and genome sequencing
• AI and machine learning models
• Industry and product development (e.g. crash tests, material analysis)

An HPC cluster is the backbone of modern high-performance computing systems. By processing large amounts of data in parallel, it performs complex calculations in a very short time, making it an indispensable tool in research, business and technology development.
