Centre for High Performance Computing SA

(Redirected from User:Derek J Moore/sandbox/Centre for High Performance Computing)

The Centre for High-Performance Computing (CHPC) was launched in 2007[1] and is a part of the National Integrated Cyber Infrastructure System (NICIS) in South Africa. The CPHC is supported by the South African Department of Science and Innovation, TENET and the Council for Scientific and Industrial Research. South Africa, in 2016, joined the Petaflop Club when the fastest computer in Africa was unveiled.[2] Dubbed "Lengau", which is a Setswana word for Cheetah;[3] this petascale system consists of Dell servers, powered by Intel processors[4]

High-performance computing

edit

High-performance computing (HPC) refers to the practice of aggregating computing power/resources of several computing nodes in a manner that delivers much higher-performance computer power.[5] HPC is measured in terms of floating point operations per second, or "FLOPS". HPCs are fast and can process thousand-trillion calculations (a petaflop).[6] HPC clusters have vast amounts of every type of resource that can bought. Every CHPC is different, as much of the configuration depends on the vendor and their budget. Neighbouring countries, research centres, and universities can use Lengau to advance scientific discovery, while commercial firms can also improve their efficiency and competitiveness. The CHPC is a critical player in making national data-intensive research infrastructure accessible across the research and higher education sectors.[7]

The CHPC offers high-performance computing facilities to academic and industry researchers who need to process data and perform complex calculations. During the pandemic, this CHPC contributed to worldwide efforts to identify the South African variant of SARS-CoV-2.[7]

Flagship projects

edit

The CHPC supports several South African flagship projects.[8] Including the

  • Square Kilometre Array (SKA), an international effort to build the world's largest radio telescope[9]
  • Student Cluster Competition, a program for undergraduate students currently enrolled in Science, Technology, Engineering and Mathematics (STEM) fields who are trained in high-performance computing skills.[10]
  • A state-of-the-art supercomputer simulations to study galaxies and their environments [11]
  • Advanced weather modelling with the South African Weather Service (SAWS) [12]

Means of production

edit

In the global north, the private sector has access to the means of production. It can process large-scale data sets, big data analytics & algorithmic data science methods on their HPC infrastructure. HPCs act as methodological gatekeepers, prescribing what forms of educational data science and methodological capital are permitted.[13] Unlike HPC infrastructures in the global north, where the means of production often lies with for-profit companies[13] or well-resourced private universities like Stanford. The CHPC (https://www.chpc.ac.za/) is state-owned and prioritises computational resources and application support for any compute-intensive or machine-learning algorithms.[14] The CPHC collaborates and shares computational clusters with neighbouring countries in the SADC region,[15] to develop relevant human capital.
