We have connected the Sitola lab to 100 GE. This is an important step in the upgrade of the CESNET backbone network. While in the past 100Gbps speeds were only available in the backbone network, today it is also possible to connect individual institutes, laboratories, scientific facilities, or even instruments at these speeds in the CESNET3 network. The Sitola laboratory is a joint laboratory of the CESNET association, the Faculty of Informatics, and the Institute of Computer Science at Masaryk University. Research in the laboratory focuses on advanced technologies for high-performance comp

MetaCentre manages these computing and data resources to solve very demanding tasks in the field of science and research. For more information, see the ZČU press relea

Yesterday, prizes were awarded to the successful solvers of our traditional CTF competition The Catch, which we organise as part of Safety Month. The most successful ones were rewarded not only with a commemorative medal but also with interesting gifts. This year's winner is a participant under the nickname "klarz", who thus joins the ranks of award-winning participants, after the Czech Republic, Slovakia, and France, with Norway.
