Development of technology and computer architecture – from 1-processor serial computers to supercomputers
On October 26, 2021 the third lecture of our „Supercomputing in science“ series took place on the premises of the Computational centre of the Slovak Academy of Sciences Doc. Šperka, who is also responsible for the Computer museum, showed development of computer architectures and it’s components, such as CPU, GPU and RAM.
Computational power increased thanks to new technologies and innovations in semiconductor device fabrication and enabled doubling the number of components per integrated circuit every two years – this trend is described by the Moore’s law. However, we are now approaching physical limits in this area.
Another way of speeding up calculations is to use parallel approach, supported by today’s supercomputer architectures, including high-speed interconnecting network. Doc. Šperka described the history from the first parallel vector computers and Cray-1 supercomputer up to modern supercomputers.
Lecture series is a joint activity of the Computer museum COO SAS and National Competence Center for HPC. NCC, as the primary contact point for HPC in Slovakia, covers, among other things, educational and dissemination activities in this area.
