Overview of High‑Performance Computing (HPC) Application Types and Domains

High‑performance computing (HPC) applications are grouped by cluster type and by the specific workload they serve.

Cluster types include scientific‑computing clusters, load‑balanced clusters, high‑availability clusters, and parallel‑database clusters.

Workloads are categorized as:

Computing‑intensive applications (e.g., large‑scale scientific engineering, numerical simulation) used in petroleum, weather forecasting, CAE, nuclear energy, pharmaceuticals, environmental analysis, and system simulation.

Data‑intensive applications (e.g., digital libraries, data warehouses, data mining, visualisation) serving libraries, banks, securities, tax authorities, and decision‑support systems.

Network‑intensive applications (e.g., collaborative work, grid computing, remote diagnosis) for websites, information centres, search engines, telecommunications and streaming services.

Typical HPC application fields include CAE simulation, animation rendering, physical‑chemical modelling, petroleum exploration, life‑science research, and meteorology.

CAE (Computer‑Aided Engineering) software assists in analysing and optimising structural performance of complex products and is widely used in aerospace, automotive, shipbuilding, mechanical, construction and electronics industries.

Finite Element Analysis (FEA) is divided into implicit (IFEA) for internal structural design and explicit (EFEA) for impact, explosion and other dynamic analyses.

Computational Fluid Dynamics (CFD) predicts fluid flow, heat transfer, mass transfer, chemical reactions and other physical phenomena.

Life‑science HPC software covers three areas:

Bioinformatics – sequencing, assembly and alignment of genomic data.

Molecular dynamics – large‑scale simulations of proteins at atomic level.

Drug discovery – high‑throughput virtual screening to shorten development cycles.

Animation rendering, a major HPC use case, follows a workflow of model abstraction, job submission, queueing, task activation, rendering execution and archival storage.

Meteorological HPC software builds mathematical models, ingests observational data and boundary conditions, and runs numerical weather prediction to forecast atmospheric conditions, following a process of data collection, preprocessing, model execution and result dissemination.

Different HPC applications consume different IT resources; compute‑intensive workloads need high‑frequency CPUs, memory‑bound workloads require high‑bandwidth large memory, network‑intensive workloads benefit from InfiniBand, and I/O‑intensive workloads need high‑bandwidth, large‑capacity parallel storage systems.
