SURF, a cooperative association of Dutch educational and research institutions dedicated to driving digital innovation in the country’s economy, is building the Netherlands’ most powerful supercomputer in the Amsterdam Data Tower at the Amsterdam Science Park.

The project, which was announced on Monday, will replace SURF’s existing supercomputer, Cartesius, with a new facility capable of delivering computing power equivalent to 14 petaflops at peak performance (roughly equal to that of 100,000 laptops). 

Chinese tech multinational Lenovo has been selected to provide the necessary infrastructure to build the machine, following the completion of a tender process on February first. Funding is being provided through an €18mn grant from the Netherlands Ministry of Education, Culture and Science, as well as €2mn from SURF’s own coffers.  

SURF, in a press statement, says it chose Lenovo’s bid due to its superior proposals in the fields of performance and sustainability, adding that the deal will allow for the largest possible amount of scientific research within the organisation’s budget. 

"Researchers' need for computing power, data storage and data processing is growing exponentially. In the design of the new supercomputer, usability for scientific research is paramount,” said Walter Lioen, manager of Research Services at SURF.  

“It is not designed for the highest ranking in the top 500 fastest supercomputers in the world. Moreover, the system must be suitable for all fields of science, from astronomy and research into climate change to medical and social sciences. In addition, we must be able to flexibly scale up the supercomputer in the future."

The new supercomputer will be built using Lenovo’s ThinkSystem servers, which use cutting edge AMD EPYC processors and the latest generation NVIDIA GPUs, which are essential to machine learning workloads

Lenovo’s cooling techniques have been selected for maximum energy efficiency, using water cooling technology that reportedly requires 90% less energy than air cooling fans. 

The installation will begin some time this month, and the new super computer is expected to be online by mid-2021. 

"We are very pleased to contribute to a project that will not only enrich scientific research in the Netherlands, but also deliver a smarter and, thanks to our water-cooling technology, more energy-efficient system,” commented Tina Borgbjerg, General Manager for Benelux and the Nordics at Lenovo DCG.

“The enormous power that this national supercomputer will deliver demonstrates our expertise in HPC, and the scale of this deal further confirms our commitment to the Benelux region and to the Netherlands."

3 ways crypto mining is impacting the data centre industry

Spiking prices of cryptocurrencies like Dogecoin and Bitcoin are driving a new subset of the data centre industry that’s as risky as it is lucrative

Around the world - particularly in Russia, Eastern Europe and China - the global rise of crypto currency values has been driving an en masse industrialisation of the mining process. The trend has been bubbling away for several years, as the home mining rig has largely found itself edged out by hyperscale server farms comprising some of the largest data centres anywhere in the industry - all designed to mine crypto. 

The demands placed on a facility built and run as a mining operation are somewhat different to those placed on a hyperscale cloud facility or enterprise data centre. Reliability isn’t so much of an issue; if a mine goes down for a few hours, money is lost, but your data centre won’t take half the websites in Western Europe down along with it. 

On the flipside, density and cooling are much, much more important. To make a crypto mining operation profitable, you need to be harvesting more crypto currency (be it Ethereum, Dogecoin, or the perennial Bitcoin) than you’re paying for electricity by a significant margin. As a result, some of the most efficient cooling and hyper-dense rack architecture from the past few years - like two-stage liquid cooling - has originated as a crypto mining solution. Now, hyperscale cloud operators in particular are recognising the benefits of these innovations and applying them to other aspects of the data centre industry.

1. Liquid Cooling 

Crypto data centres have always been as dense as possible, with their racks running at maximum capacity all day, all year round. By contrast, the average enterprise or cloud data centre isn’t necessarily running at peak capacity 24/7; workloads fluctuate with demand. However, as that demand has skyrocketed over the past year in particular, cloud and enterprise operators have looked to crypto’s preference for liquid cooling as a way to run data centres closer to the ragged edge of performance than ever before. 

One example of this is LiquidStack. The Hong Kong startup makes a revolutionary two-phase liquid cooling solution for data centres, which was developed over a number of years inside Bitfury, one of the world’s leading crypto miners. “Bitfury is sharing our knowledge with the global data center community and we are excited that Microsoft and other internet giants can benefit from our years of experience and investment to best practice liquid cooling,” said Joe Capes, CEO of LiquidStack in an interview with Data Centre Magazine. 

Now, LiquidStack is going mainstream, with substantiated rumours that Microsoft is looking to adopt their DataTank solutions across its ever-expanding portfolio of hyperscale cloud regions. 

2. Denser HPC 

One of the issues that liquid cooling solves is how to create ultra-dense server racks that can function at high temperatures. Crypto miners have been grappling with this problem for about a decade now, and the lessons they’ve learned are being happily adopted by the burgeoning data centre HPC market - which is swelling in response to greater AI adoption and increasingly-sizable data sets. 

With the density that mining rigs can achieve, server architects are cramming hundreds of kilowatts into individual racks - although it should be noted that this is still relatively rare. A 2020 survey from the Uptime Institute still found that the average density of data centre racks was growing rapidly, however. 

“We expect density to keep rising. Our research shows that the use of virtualization and software containers pushes IT utilization up, in turn requiring more power and cooling. With Moore’s law slowing down, improvements in IT can require more multi-core processors and, consequently, more power consumption per operation, especially if utilization is low. Even setting aside new workloads, increases in density can be regarded a long-term trend,” said the report. 

In 2020, average rack densities of 20kW and higher became a reality for many data centre operator. 

3. Sustainability Concerns 

Now for the more worrying news. The industrial scale and massive power consumption inherent to the crypto mining business - and the negative attention that miners are now starting to receive from government - could point towards a concerning future for data centre operators in the wider industry. 

Last week, the Chinese government announced that it would open an inquiry into the participation of Beijing’s largest data centre operators - which include the country’s three largest telecom firms - in crypto mining. At a time when the PRC government is attempting a significant reversal of its approach towards sustainability, the significant power draw of crypto mining activities may be one more hurdle than China cares to deal with. 

The Indian government is mulling a blanket criminalisation of all crypto mining in the country and, in the US, the State of New York is also looking into tightening regulatory restrictions on the industry. 

While crypto mining data centres are not the same as cloud or enterprise facilities, operators should be careful lest the ire of lawmakers be the latest trend to make its way from the crypto sector into the mainstream.
