Building Europe's AI Stack — Inside the Barcelona Supercomputing Center

We sat down with the Barcelona Supercomputing Center to talk about what it really takes to turn a continent's scientific ambition into an AI powerhouse. BSC hosts MareNostrum 5 — one of the largest supercomputers in Europe. But raw compute is just the start. The BSC AI Factory, backed by the European Commission, is doing something harder: compressing the journey from idea to deployable AI product for the startups and SMEs who can't afford to wait. The model is simple in concept, hard to execute: energy → chips → infrastructure → models → applications. Five layers. One coherent stack.
