The Barcelona Supercomputing Center, Centro Nacional de Supercomputación (BSC-CNS) is the national centre for supercomputing in Spain and one of Europe's main hubs for high-performance computing (HPC). Founded in 2005, the centre manages MareNostrum, one of Europe's most powerful supercomputers, serving international scientific and industrial demand for advanced computational resources. The BSC plays a central role in the European HPC ecosystem: it coordinates the Spanish Supercomputing Network (RES), was a founding member of Partnership for Advanced Computing in Europe (PRACE), and is now the host body of the EuroHPC JU, supporting investment in and access to large-scale HPC infrastructure. The centre is characterised by a multidisciplinary research approach that includes several fields: Computer Science, Life Sciences, Earth Sciences, Computational Engineering, and Computational Social and Humanities, developed in close collaboration with European universities, industry, and research programs. The centre inherits the know-how of the former European Centre for Parallelism in Barcelona (CEPBA). This consolidates decades of experience in efficient computing technologies and scientific applications. Over time, the BSC has become a European benchmark for attracting talent and promoting HPC as a strategic tool for competitiveness, technological autonomy, and innovation.
