The project is called Alya Red and the goal is fairly straightforward: to make an anatomically accurate computer simulation of one of the most complex systems in the human body. The amount of math necessary to simulate the electrical impulses that drive heartbeats takes 10,000 separate processors. The supercomputer, one of the 500 most powerful in the world, driving this simulation is housed in a deconsecrated 19th-century chapel called Torre Girona, now home to the Polytechnic University of Catalonia. This video is not to be missed.
