Hawk Supercomputer Powers Analysis on Quieter Fanatics, Motors

If you happen to’ve ever been in a supercomputer datacenter, you’ll know that they don’t have a tendency to be quiet puts – however now, supercomputing helps make some equipment hum quieter. ebm-papst, a German fan and electrical motor producer, is making use of the Hawk supercomputer on the Top-Efficiency Computing Middle Stuttgart (HLRS) to know how and why its merchandise produce noise.

To know noise – a topic of significance for lots of of ebm-papst’s people-proximate merchandise – the corporate runs wind tunnel experiments at their headquarters, equipping their prototypes with arrays of hyper-sensitive microphones to spot the origins of any noise. However this can be a exhausting, equipment-intensive procedure – and HPC can lend a hand lighten the weight. To that finish, the researchers additionally run aeroacoustic simulations, which might be a area of expertise for Andreas Lucius, an engineer at ebm-papst.

“Each time we habits an experiment we want to construct a prototype, function the wind tunnel, and make measurements. All of the ones issues price money and time,” Lucius defined in an interview with HLRS’ Christopher Williams. “Because the precision of aeroacoustic simulations will get higher, this way has monumental doable to economize and accelerate the improvement procedure.”

“We’ve got a small computing cluster this is enough for lots of conventional aerodynamics simulations, however aeroacoustic simulations require extra efficiency,” Lucius stated. “We want to use an overly superb computational mesh and different forms of modeling approaches in an effort to get to the bottom of small turbulent buildings. This will temporarily expend greater than 10,000 CPU hours, calls for extremely paralleled {hardware}, and takes too lengthy on our personal methods. In eventualities like those, getting access to HLRS’ supercomputer is helping us to get our effects a lot sooner.”

The supercomputer in query: Hawk (pictured within the header), a 5,632-node HPE-built gadget powered via AMD CPUs that delivers 25.16 Linpack petaflops, striking it thirtieth on the newest Top500 checklist.

The use of Hawk, the researchers simulate the operation of a given tool and establish miniscule ranges of undesirable turbulence that would possibly induce noise. ebm-papst says those simulations lend a hand them extra temporarily iterate and expand quieter fan and motor designs. In reality, the simulations have additionally helped beef up the trying out atmosphere: in a single example, a virtual dual of a fan and the trying out atmosphere was once in a position to lend a hand researchers establish (and get rid of) the supply of an sudden noise within the recording – an errant form of a few insulation paneling.

Lucius stated that computing is turning into a big attention for them, specifically when running with shoppers to combine ebm-papst’s merchandise into advanced package.

“Right here we’re now not speaking about 10,000 CPU-hours, however extra like 100,000 CPU-hours,” Lucius stated. “Those are eventualities which are very attention-grabbing and we’re these days looking for strategies that would cut back computing time even for such advanced instances. Our objective isn’t just as a way to analyze the aeroacoustics of such advanced set up instances, but in addition to optimize them mathematically the usage of many simulation runs.”
