Dr. Happy Sithole speaks to Balungile Belz to explain why Lengau, a supercomputer developed by South Africa's Council for Scientific and Industrial Research (CSIR) and its partners, is important for Afrikaโ€™s development. Lengau is a super computer with processing speed capable of a thousand-trillion floating point operations per second (FLOPs). Floating point operations or flops are used in computing to calculate extremely long numbers.

With over 40 000 cores, the machine is the fastest computer on the African continent owing to its speed of roughly one petaflops (1000 teraflops) which is 15 times faster than the previous system named Tsessebe (Setswana for Antelope).
