Dedicated CHPC Resources for COVID19

Given the unprecedented COVID19 challenge we are all facing, the Centre for High Performance Computing (CHPC) is willing and ready to make compute resources available for dedicated COVID19 research.

Please note that wider cyber-infrastructure support beyond only compute resources, e.g. network, data transfer, data analyses, etc.) may also be possible through the CHPC NICIS partners, i.e. SANReN and DIRISA.

Researchers that are actively involved in direct or indirect research on COVID-19 (or planning to become involved), and who need access to resources to successfully pursue COVID19 research, are encouraged to contact the CHPC using details below.

CHPC Initiatives in Data and HPC in South Africa

The centre has recently launched the Data Intensive Research Infrastructure of South Africa (Dirisa).

The infrastructure has a storage facility of two petabytes and is accessible through the South African National Research Network. It operates at a full capacity of 10 Gps/s and provides the latest technology which is based on open source software to enable CHPC users to define their own rules in data acquisition, sharing and curation. The establishment phase was funded by the Department of Science and Technology, following a positive report on the 2007 feasibility study.

The centre has completed the full migration of data portals in Climate Modelling, Astronomy and Earth Observation and is currently migrating data portals in Humanities, medical applications on Rheumatic Heart Disease data and Bioinformatics data on genomic sequencing, amongst others.

Work is underway to drive the identification and curation of other critical research data in order to make it accessible to a wider community. There are also plans to expand the current storage capacity of 2 petabytes to enable sufficient access by the CHPC's other strategic partners.

CHPC Scheduled Maintenance Dates for 2020

General availability

Every reasonable effort will be made to keep our HPC resources available and operational 24 hours per day and 7 days per week. Please note however that although the support personnel will do their best to keep the facility running at all times, We cannot guarantee to promptly resolve problems outside RSA office hours, and during weekends and public holidays. Nevertheless, Please notify This email address is being protected from spambots. You need JavaScript enabled to view it. of any issues whenever they arise.

Planned maintenance
Occasionally it is necessary as part of maintaining a reliable service to update system software and replace faulty hardware. Sometimes it will be possible to perform these tasks transparently by means of queue reconfiguration in a way that will not disrupt running jobs or interactive use, or significantly inconvenience users. Some tasks however, particularly those affecting storage or login nodes, may require temporary interruption of service.

Where possible, maintenance activities involving a level of disruption to service will be scheduled on every last Friday of each month if required starting from 08:00 - 16:30 ( local RSA time). Please see the below provisional date for planned maintenance.
  1. 31 January 2020
  2. 28 February 2020
  3. 27 March 2020
  4. 24 April 2020
  5. 29 May 2020
  6. 26 June 2020
  7. 31 July 2020
  8. 28 August 2020
  9. 25 September 2020
  10. 30 October 2020
  11. 27 November 2020
  12. 18 December 2020
Please note that this does not mean that there will be disruption every month, merely that if potentially disruptive maintenance is necessary we will do our best to ensure it takes place during this period, in that case there will be advance notification.

Establishing a provisional time slot for planned maintenance has the advantage that users may be confident that `dangerous' changes will not intentionally be undertaken at other times.

Exceptional maintenance and unplanned disruptions
It may happen that despite best efforts, it becomes necessary to reduce or withdraw service at short notice and/or outside the planned maintenance time slot. This may happen e.g. for environmental reasons, such as air conditioning or power failure, or in an emergency where immediate shutdown is required to save equipment or data.

Future challenges see industry finding its way to high performance computing


26 March 2012

South Africa’s Centre for High Performance Computing (CHPC) now has over 500 users from across the science and engineering domains. Traditional users of the centre have been higher education institutions and research councils. However, ever-mounting pressures on industry to grow their business and to become more competitive, have led a number of companies to the CHPC.

The CSIR’s Research Impact Area (RIA) strategy for the advanced manufacturing industry seeks to achieve significant impact through the development and transfer of manufacturing technologies that improve the competitiveness of existing South African industry while also creating new manufacturing opportunities. CHPC industry partners such as Sasol, Hatch and others are using the facility to conduct computationally intensive research that seeks to advance their products and increase their competitive edge. They have access to the facilities without long-term commitment, which translates to cost-effective access.
