HPC Cluster

An HPC cluster is a type of computing system that consists of multiple interconnected computers or nodes working together to provide high-performance computing capabilities.

Component of HPC Cluster

• Cluster includes servers, networks and storage.
• Partitions: Collection of nodes
• Node (server): Contains multiple processors.
• Processor: Contains multiple cores. Eg: CPU and GPU.
• Core: Receives instructions and performs calculations.

Nodes

• Login nodes: The secure entry point to the cluster, where users can submit jobs, manage files, and interact with the cluster.
• Compute nodes: Perform the actual computation tasks requested by users.
• Storage nodes: High-capacity, high-performance storage for user data and applications that are connected to the compute nodes via a high-speed network.
• Data transfer nodes: Dedicated to high-speed data transfer between the cluster and external networks or storage systems.
