When designing the aerodynamics for each single certainly one of their new fashions, automaker SEAT makes use of Spain’s strongest super-computer, dubbed MareNostrum four.
Other than having the uncooked energy of 40,000 PCs and being housed in a 180-square meter disused chapel on the Polytechnic College of Catalonia in Barcelona, the MareNostrum four can be the seventh strongest pc in Europe, that includes an enormous 165,888 processors.
Different options embody its three,456 nodes, 6,912 chips, 13.7 petaflops and 78,000 kg (171,960 lbs) total weight. It’s no marvel that scientists already use it to simulate the whole lot from how the human coronary heart works to creating predictions about local weather change.
In the meantime, SEAT engineers use it to finish evaluation that may in any other case take months, in just some hours – analyzing automobile aerodynamics in an try to decrease their air drag coefficient.

“With SEAT, I research the affect of wheel hub geometry on the aerodynamics of the vehicles. Every level is analyzed by a set of processors working in parallel. In the event that they had been analyzed individually, it might take months,” stated BSC researcher Oriol Lehmkuhl.
“Working with a wind tunnel is dear and clay fashions deteriorate, so fixed modifications need to be made. The computing energy of the BSC supercomputer allows us to incorporate extra parameters to see how air behaves inside the edges when the wheels are transferring. The concept is to more and more slim the hole between simulation and actuality,” added SEAT aerodynamics engineer, Maria Garcia-Navas.
Proper now, a next-gen MareNostrum 5 is already below improvement and is anticipated to extend the present mannequin’s capability by greater than 20 instances.
