They&#8217;ve now built a pipeline of talent,&#8221; said Johnston.<\/p>\n\n\n\n<p>At Wits, the HPC and Big Data Interest Group recently attended an international competition using the CSIR-provided hardware as its infrastructure backbone.<\/p>\n\n\n\n<p>The student-led group used the hardware to run massively complex weather simulations, protein-folding problems, and fluid dynamics models.<\/p>\n\n\n\n<p>&#8220;The protein folding example was exciting for me because it was the first time I saw my visualisation at one of these competitions,&#8221; said Wits student Kevin Ebrahim.<\/p>\n\n\n\n<p>&#8220;It was very eye-opening to see all the work that went into just a simple video clip of the protein folding.&#8221;<\/p>\n\n\n\n<p>Reinhard Jansen van Vuuren, a senior member of the Wits HPC group, said the team&#8217;s weather simulations were important for understanding climate change.<\/p>\n\n\n\n<p>&#8220;In these simulations, you&#8217;re able to predict heatwaves, storms, rain, and different pressures in certain areas,&#8221; he said.<\/p>\n\n\n\n<p>&#8220;All of these are then combined to provide not only visuals, but also data to predict natural disasters.&#8221;<\/p>\n\n\n\n<p>He said that the collaboration with the CSIR and the HPC Ecosystems Project was the backbone of the group, and the reason Wits can do the teaching and competitions it can.<\/p>\n\n\n\n<p>&#8220;The resources we have from them are what we use to teach, to train and to learn, and it allowed us to build a little ecosystem within Wits.&#8221;<\/p>\n\n\n\n<p>Internationally, the HPC Ecosystems Project has evolved into a global ecosystem and has won international awards.<\/p>\n\n\n\n<p>The project aimed to begin sending decommissioned HPC hardware to Angola and the Democratic Republic of Congo (DRC) after a need was identified there.<\/p>\n\n\n\n<p>It has deployed infrastructure across the continent, including South Africa, Madagascar, Mauritius, Malawi, Lesotho, Eswatini, Botswana, Namibia, Zambia, and Kenya.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2
