The Centre for High Performance Computing (CHPC) at the Council for Scientific and Industrial Research (CSIR) on Tuesday unveiled Africa's fastest computer.
The powerful machine has a speed of one petaflops, meaning is can process a thousand-trillion floating point operations per second.
Named Lengau (the Setswana word for 'cheetah'), the supercomputer has over 40 000 cores and is 15 times faster than its predecessor - marking significant progress by engineers.
But why is this important?
" or our country to grow at the required rate, as set out in the National Development Plan, it needs to change gear by building capacity in the production and dissemination of knowledge," Dr Thomas Auf der Heyde, Deputy Director-General: Research Development and Support at the Department of Science and Technology, said at the unveiling of the computer.
"The CHPC represents a deliberate move by this country to invest in modernising our research and development. High-performance computing and advanced data technologies are powerful tools in enhancing the competiveness of regions and nations," he said.
It is likely that Lengau will feature among the world top 200 fastest computers.
Dell collaborated with the CSIR to create the computing beast.
