Driving Efficiency, Liquid Cooled GPUs Debut at Computex


Within the worldwide effort to halt local weather change, Zac Smith is a part of a rising motion to construct information facilities that ship each excessive efficiency and vitality effectivity.

He’s head of edge infrastructure at Equinix, a world service supplier that manages greater than 240 information facilities and is dedicated to changing into the primary in its sector to be local weather impartial.

“We now have 10,000 clients relying on us for assist with this journey. They demand extra information and extra intelligence, typically with AI, they usually need it in a sustainable method,” stated Smith, a Julliard grad who acquired into tech within the early 2000’s constructing web sites for fellow musicians in New York Metropolis.

Marking Progress in Effectivity

As of April, Equinix has issued $4.9 billion in inexperienced bonds. They’re investment-grade devices Equinix will apply to lowering environmental influence by means of optimizing energy utilization effectiveness (PUE), an trade metric of how a lot of the vitality a knowledge heart makes use of goes on to computing duties.

Information heart operators try to shave that ratio ever nearer to the best of 1.0 PUE.  Equinix amenities have a median 1.48 PUE at this time with its finest new information facilities hitting lower than 1.2.

Equinix is making regular progress within the vitality effectivity of its information facilities as measured by PUE (inset).

In one other step ahead, Equinix opened in January a devoted facility to pursue advances in vitality effectivity. One a part of that work focuses on liquid cooling.

Born within the mainframe period, liquid cooling is maturing within the age of AI. It’s now extensively used contained in the world’s quickest supercomputers in a contemporary type referred to as direct-chip cooling.

Liquid cooling is the following step in accelerated computing for NVIDIA GPUs that already ship as much as 20x higher vitality effectivity on AI inference and excessive efficiency computing jobs than CPUs.

Effectivity By Acceleration 

If you happen to switched all of the CPU-only servers working AI and HPC worldwide to GPU-accelerated programs, you might save a whopping 11 trillion watt-hours of vitality a 12 months. That’s like saving the vitality greater than 1.5 million properties eat in a 12 months.

Immediately, NVIDIA provides to its sustainability efforts with the discharge of our first information heart PCIe GPU utilizing direct-chip cooling.

Equinix is qualifying the A100 80GB PCIe Liquid-Cooled GPU to be used in its information facilities as a part of a complete strategy to sustainable cooling and warmth seize. The GPUs are sampling now and will likely be typically out there this summer season.

Saving Water and Energy

“This marks the primary liquid-cooled GPU launched to our lab, and that’s thrilling for us as a result of our clients are hungry for sustainable methods to harness AI,” stated Smith.

Information heart operators goal to remove chillers that evaporate thousands and thousands of gallons a water a 12 months to chill the air inside information facilities. Liquid cooling guarantees programs that recycle small quantities of fluids in closed programs centered on key scorching spots.

“We’ll flip a waste into an asset,” he stated.

Identical Efficiency, Much less Energy

In separate assessments, each Equinix and NVIDIA discovered a knowledge heart utilizing liquid cooling might run the identical workloads as an air-cooled facility whereas utilizing about 30 p.c much less vitality. NVIDIA estimates the liquid-cooled information heart might hit 1.15 PUE, far under 1.6 for its air-cooled cousin.

Liquid-cooled information facilities can pack twice as a lot computing into the identical house, too. That’s as a result of the A100 GPUs use only one PCIe slot; air-cooled A100 GPUs fill two.

NVIDIA sees energy financial savings, density good points with liquid cooling.

A minimum of a dozen system makers plan to include these GPUs into their choices later this 12 months. They embody ASUS, ASRock Rack, Foxconn Industrial Web, GIGABYTE, H3C, Inspur, Inventec, Nettrix, QCT, Supermicro, Wiwynn and xFusion.

A International Pattern

Laws setting energy-efficiency requirements are pending in Asia, Europe and the U.S. That’s motivating banks and different giant information heart operators to guage liquid cooling, too.

And the expertise isn’t restricted to information facilities. Automobiles and different programs want it to chill high-performance programs embedded inside confined areas.

The Highway to Sustainability

“That is the beginning of a journey,” stated Smith of the debut of liquid-cooled mainstream accelerators.

Certainly, we plan to comply with up the A100 PCIe card with a model subsequent 12 months utilizing the H100 Tensor Core GPU based mostly on the NVIDIA Hopper structure. We plan to help liquid cooling in our high-performance information heart GPUs and our NVIDIA HGX platforms for the foreseeable future.

For quick adoption, at this time’s liquid-cooled GPUs ship the identical efficiency for much less vitality. Sooner or later, we anticipate these playing cards will present an choice of getting extra efficiency for a similar vitality, one thing customers say they need.

“Measuring wattage alone will not be related, the efficiency you get for the carbon influence you’ve got is what we have to drive towards,” stated Smith.
