Contents

CHPC (South Africa) is a national high-performance computing facility providing supercomputing, data storage, and computational support across multiple scientific and engineering domains. The centre supports researchers from institutions such as University of Cape Town, Stellenbosch University, University of the Witwatersrand, University of Pretoria, and Council for Scientific and Industrial Research while interfacing with regional networks like SANReN, TENET, and international initiatives such as PRACE and HPC Wales. It underpins projects linked to agencies including National Research Foundation (South Africa), Department of Science and Innovation (South Africa), South African National Space Agency, and global programs like Square Kilometre Array and World Health Organization-related modelling efforts.

Overview

The centre offers centralised compute resources, specialist support, and training for computational science, numerical modelling, and data-intensive research, serving communities that include astronomy, climate science, bioinformatics, computational chemistry, and materials science. Its user base spans academics affiliated to Rhodes University, North-West University, Nelson Mandela University, University of Johannesburg, and research organisations such as Agricultural Research Council, Medical Research Council (South Africa), and Mintek while engaging with international consortia like European Space Agency, NASA, CERN, International Centre for Theoretical Physics, and CODATA. The facility integrates with training programmes run by institutions such as HPC Advisory Council, Carnegie Mellon University, Massachusetts Institute of Technology, and University of Oxford.

Established in the mid-2000s, the centre evolved from national calls by National Research Foundation (South Africa) and policy frameworks from Department of Science and Innovation (South Africa) to address computational gaps experienced by universities such as University of Cape Town and University of the Witwatersrand. Early milestones included procurement cycles coordinated with vendors like IBM, Hewlett-Packard, and Cray, collaborations with network providers TENET and SANReN, and project funding linked to initiatives such as Square Kilometre Array and Horizon 2020. Major upgrades paralleled global trends led by organisations like Top500 and OpenMPI, while technical partnerships drew on expertise from NERSC, PRACE, Compute Canada, and AARNet.

The centre hosts production clusters, data storage arrays, and visualization nodes built from components supplied by vendors such as Dell Technologies, HPE, NVIDIA, and Intel. Infrastructure includes high-speed interconnects like InfiniBand, parallel file systems that follow models used at Oak Ridge National Laboratory and Lawrence Berkeley National Laboratory, and user-facing services comparable to offerings at European Centre for Medium-Range Weather Forecasts and NOAA. Physical facilities occupy secure data halls with cooling and power arrangements coordinated with local utilities and municipal services tied to City of Cape Town, while backup strategies mirror architectures from Google, Amazon Web Services, and Microsoft Azure for resilience.

The centre supports computational campaigns in astrophysics for instruments such as MeerKAT and Square Kilometre Array, climate modelling for regional studies comparable to outputs from IPCC, genomic analyses in collaboration with Broad Institute-style consortia, and materials design workflows employed by groups at Max Planck Society and Lawrence Livermore National Laboratory. Projects have produced simulations analogous to work at Los Alamos National Laboratory, machine learning experiments inspired by efforts at DeepMind and OpenAI, and epidemiological models related to initiatives from World Health Organization and Wellcome Trust. Cross-disciplinary studies link to urban modelling used by UN-Habitat and oceanography comparable to programs at Scripps Institution of Oceanography.

Partnerships include academic nodes such as University of Cape Town, Stellenbosch University, University of Pretoria, and University of the Western Cape; national agencies like National Research Foundation (South Africa) and South African National Space Agency; and international partners including PRACE, NERSC, CERN, European Space Agency, and NASA. Technology alliances have involved NVIDIA for GPU deployments, Intel for CPU roadmaps, HPE and Dell Technologies for system procurement, and network cooperation with TENET, SANReN, and Internet2-style providers. Capacity-building collaborations mirror programmes run by ACM, IEEE, Carnegie Mellon University, and University of Oxford.

Governance is structured through oversight and funding mechanisms driven by organisations such as National Research Foundation (South Africa), Department of Science and Innovation (South Africa), and partner universities including University of Cape Town and Stellenbosch University, with advisory input from stakeholders resembling boards in European Research Council and National Science Foundation (United States). Funding sources have combined national grants, project-based support from bodies like Horizon 2020 and Wellcome Trust, and procurement agreements with vendors such as IBM and Cray. Operational policies align with standards and best practices promoted by OpenStack Foundation, Linux Foundation, Open MPI, and international benchmarking communities like Top500.
