For the first time during the heritage days, visit the IN2P3 Computing Center. As a national research infrastructure, the CC-IN2P3 is a CNRS unit that processes computer data from the largest scientific experiments in high-energy physics. The CC-IN2P3 has two computer rooms hosting several thousand servers and libraries to store nearly 340 petabytes of data on magnetic tapes. Come and discover this gem of the CNRS’s computer heritage during a 45-minute guided tour (without prior reservation).
