we provide state-of-the-art national supercomputing infrastructure
IT4Innovations is a strategic research infrastructure in the Czech Republic and together with another two infrastructures CESNET and CERIT-SC constitutes e-Infrastructure of the Czech Republic called e-INFRA CZ.
The first supercomputer installed at IT4Innovations was Anselm (94 TFlop/s, installed in the summer of 2013), the operation of which was ceased at the beginning of 2021. Just after its launch in 2015, the Salomon supercomputer with a theoretical peak performance of 2 PFlop/s ranked 40th in the TOP500 list of the most powerful supercomputers in the world. To our users, we have also been providing our specialized NVIDIA DGX-2 system for artificial intelligence with a theoretical peak performance of 130 TFlop/s as well as the extension of the Anselm supercomputer, Barbora,with a theoretical peak performance of 849 TFlop/s built on the latest supercomputing technologies since 2019.
In cooperation with the EuroHPC JU initiative, bringing together important European supercomputing centres, the Karolina supercomputer with a peak performace of 15.2 PFlop/s will be put in operation in IT4Innovations in 2021. We anticipate that this new supercomputer will rank among the first twenty and fifty most powerful supercomputers in Europe and worldwide, respectively.
Our supercomputers are located in a data room with an area of 500 m2 equipped with an elevated floor with a bearing capacity of up to 2.5 t/m2. Under the floor, there is enough space for the power supply system and inlet and outlet of warm water (30-55 °C) and cold water (6-28 °C) supplies, equipped with valves for easy connection of cold water-cooled racks.
The data room is equipped with a fire protection system based on active reduction of oxygen concentration to a level of about 15 %, which physically prevent a fire from starting and spreading.
The data room also has up to 2.5 MW of fully redundant power supply backed up by its own redundant Dynamic UPS. This power supply is cooled by 5 separate cooling circuits, which are equipped with 11 cooling devices of three types and power.
Part of the data room is also comprised of redundant data connections to the national CESNET network, as well as to the Internet.
