This week, we’re taking you to visit one of most powerful computers in the world! It’s called MareNostrum 4, and it’s housed in a former chapel in Barcelona, Spain. We’ll find out how scientists are using supercomputers to tackle some of the world’s biggest problems. Researchers Eduard Porta and Claudia Rosas explain what it’s like to work with one of the fastest machines in the world.

See photos from Lindsay’s visit to MareNostrum 4, and learn more about supercomputers on our blog.
