The PLEIADI partition delivered ~250k CORE hours supporting astrophysical simulations and data processing. The LOFAR partition consumed ~510k CORE hours for radio astronomy data processing. Key infrastructure improvements include the implementation of an automatic node power-down system, reducing idle power consumption by 61%.ELETTRONICOenTechnical reporthttps://doi.org/10.20371/INAF/TechRep/372
