MareNostrum 5 is a heterogeneous EuroHPC supercomputer installed at the Barcelona Supercomputing Center. Its Lenovo Neptune liquid-cooled CPU partition spans 6,400 Sapphire Rapids nodes delivering 40 petaflops, complemented by accelerator nodes with NVIDIA H100 GPUs and experimental European technologies for AI workflows. Warm-water cooling and building heat reuse keep PUE near 1.1 while the 314-petaflop system powers programs like Destination Earth’s climate digital twins, precision medicine, and sovereign European language models.
