With a booth, EuroCC@Greece took part in the Science Festival (ASF) held in Technopolis City of Athens from October 21–23, 2022.  In addition to learning about the EUROCC project, which aims to enable computational science in the Open Science Era from an early age, hundreds of children and their professors participated.  Partners from BRFAA, the National Infrastructures for Research and Technology (which coordinates EuroCC@Greece), and the Computational-based Science and Technology Research Centre (CaSToRC) of the Institute of Cyprus (which coordinates EuroCC@Cyprus) participated in the booth. They gave presentations on how computational science is made possible by the HPC programs, such as EOSC and NI4OS projects, and the EuroCC project.
