Located at the Barcelona Supercomputing Center, MareNostrum 5 is part of a network of European supercomputers and is used to conduct research in fields such as biomedicine, geophysics, atmosphere, energy, society and economy, providing valuable data to the international scientific community.

Gerard Escaich Folch visits the picturesque chapel Torre Girona, where the MareNostrum supercomputer is installed. There, he meets José María Cela Espín, the director of Computer Applications in Science and Engineering at the Barcelona Supercomputer Centre. His department uses the 314 petaflops of MareNostrum 5’s processing power to develop software to efficiently exploit super-computing capabilities through the simulations and modeling. A flop is the unit to define how powerful a computer is, and is based on the number of calculations per second it can make. A standard computer would take 46 years to perform what MareNostrum 5 can achieve in just one hour.

Host Beth Cohen learns about the future of computing and we talk to Jan Nogué, a quantum engineer from Qilimanjaro Quantum Tech responsible for building the groundbreaking computer at BSC. We also discuss the cybersecurity risks associated with these new technologies and the measures that the BSC is taking to remain one step ahead of the hackers.

This week’s Catalan phrase is ‘Aquí hi ha gat amagat!’ which translates literally as ‘There is a cat shut in here!’. It is used to express suspicion that there is more to something than meets the eye… Rather like the case of Schrödinger’s cat, which can be simultaneously alive and dead, or that of qubits, the unit of measurement used in quantum computing.
