IIT4Innovations National Supercomputing Center at VSB – Technical University of Ostrava is a leading research, development, and innovation centre active in the field of high-performance computing (HPC) and data analysis (HPDA). IT4Innovations operates the most powerful supercomputing systems in the Czech Republic, which are provided to Czech and foreign research teams from both academia and industry. Together with the CESNET and CERIT-SC institutions, IT4Innovations constitutes e-INFRA CZ, a strategic research infrastructure of the Czech Republic. It currently operates four supercomputers — Anselm (launched in summer of 2013, 94 TFlop/s), Salomon (launched in summer of 2015, 2 PFlop/s), Barbora (launched in autumn of 2019, 849 TFlop/s), and NVIDIA DGX-2, a specialized system for artificial intelligence calculations, (launched in spring of 2019, 130 TFlop/s ando 2 PFlop/s in AI). In 2021, a petascale system Karolina with a theoretical peak performance of about 15.2 PFlop/s is to be launched within the EuroHPC Joint Undertaking project.

The key research areas of IT4Innovations include big data processing and analysis, machine learning, development of parallel scalable algorithms, solution of computationally demanding engineering problems, advanced visualization, virtual reality, modelling for nanotechnologies, and material design.  For more information, see
