IT4Innovations National Supercomputing Center (hereinafter IT4Innovations) is a university research institute of VSB –Technical University of Ostrava. IT4Innovations is a leading research, development, and innovation centre active in the field of high-performance computing (HPC), high-performance data analysis (HPDA), and artificial intelligence (AI) operating the most powerful supercomputing systems in the Czech Republic. In these fields, IT4Innovations provides latest technologies as well as expertise to both Czech and international research teams from academia and industry. At the same time, IT4Innovations plays a role of the national research infrastructure.Together with another two national infrastructures, CESNET and CERIT-SC, IT4Innovations constitutes a unique e-infrastructure of the Czech Republic called e-INFRA CZ, which is listed on the National Roadmap for Large Infrastructures for Research, Experimental Development and Innovations, prepared by the Ministry of Education, Youth and Sports of the Czech Republic. Moreover, it is the national node of PRACE (the Partnership for Advanced Computing in Europe –a Pan-European e-infrastructure), and is a member of EuroHPC Joint Undertaking (building a European exascale supercomputer), ETP4HPC (European Technology Platform for High Performance Computing), DBVA/DAIRO (Big Data Value Association), and EUDAT (Collaborative Data Infrastructure), HiPEAC (High Performance Embedded Architectures and Compilers), and I4MS (ICT Innovation for Manufacturing SMEs). IT4Innovations is also registered by the European Commission as a Digital Innovation Hub in the fields of HPC, artificial intelligence, and advanced data analysis. IT4Innovations provides computational resources, know-how and expertise to academia and industry across the Czech Republic and to the European HPC community as well.At present, IT4Innovations is running three supercomputers: Salomon (2 PFlop/s, installed in the summer of 2015), Barbora (849 TFlop/s, installed in the autumn of 2019), and the specialized NVIDIA DGX-2 system for artificial intelligence computation, (2 PFlop/s in AI, installed in the spring of 2019). Moreover, the brand-new petascale Karolina supercomputer with a theoretical peak performance of 15.2 PFlop/s was installed at the centre in 2021 as part of the EuroHPC Joint Undertaking becoming the most powerful supercomputer in the Czech Republic.
