FZU Computing Centre

The FZU Computing Centre, part of the Institute of Physics of the AS CR, has evolved significantly since its inception in 2002. It supports high-energy physics experiments like D0 at Fermilab and LHC experiments at CERN, as well as solid-state and astroparticle physics research. With substantial computing power and storage capabilities, including over 3000 cores for high-energy physics analysis, the centre has undergone significant hardware upgrades and improvements in network infrastructure to enhance data processing efficiency.
