Don't waste your energy on Docker, it says here – wait, that can't be right...

Docker may be the darling of DevOps, but it's something of a minor extravagance when it comes to energy consumption. Computer science boffins affiliated with the University of Alberta in Canada have spent some time comparing the energy used running software applications in Docker containers with power consumption on bare metal …

IBM to launch cheap 'n' cheerful Power server for i and AIX userbase

IBM's i and AIX customer bases can buy a cheaper box; its latest Power S812 server comes with just one socket and a single or quad-core processor. It's for relatively light use, in the retail area for example, and as an entry point for non-compute-intense workloads. The S812 box, separate from the 2014 S812L Linux system, is …

Australia teases binning x86 for Power CPUs in new supercomputer

Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) has issued a (regwalled) tender for a new petaflop-class supercomputer that can run either x86 or Power systems silicon. But those keen to declare Intel's high-end reign is coming to an end should not get too excited: the tender may mention Power …

Inside Electric Mountain: Britain's biggest rechargeable battery

From the outside, Elidir Mountain looks like an old industrial site that has returned to nature. The slopes facing the Llyn Peris reservoir have been hacked into terraces by slate quarrying – this was once the second-biggest quarry in the world, with 3,000 workers – but they are now peaceful. Only a few buildings at ground …

Opera claims 50 per cent power savings with browser update

Browser minnow Opera may have less than two per cent of the market, but thinks the 50 per cent boost to battery life it's baked into a new browser will help it to do better. "Modern processors do an amazing job in saving power by taking tiny naps multiple times per second, and what our development team focused on was writing …

Hate noisy jets above you? What if they were charging your phone?

A researcher with Boeing has floated a plan to convert the noise from departing planes into a power source. A US patent application filing by Chin H Toh of the Boeing Company published earlier this week describes a method for using the energy from acoustic waves made by jet engines to power a turbine and generate electricity …

Power10 ... 2020 ... 10nm – suddenly IBM snaps awake, scribbles notes

IBM is dreaming of rolling out Power10 chips using a 10nm process size from 2020, it has emerged. This is rather telling: this means that even though Big Blue has boasted that it has cracked the 7nm barrier, we're not likely to see any IBM chips using that process size until 2023 at the earliest. Back to the Power10 …

Want longer battery life? Avoid the New York Times and The Grauniad

Software developer Santeri Paavolainen says the code powering today's websites is taxing browsers so much, it's having a significant impact on power consumption. The programmer came to that conclusion after a casual examination of news sites including the New Scientist, the BBC, Forbes, The Guardian, and The New York Times, as …

Forget the density, just unlock your cloud's power sweet spot

Talk to a friend or colleague in IT, and pretty soon you’ll get on the topic of big data, the data explosions, and mega data centres. Bar stool logic — and prevailing wisdom — suggests there is no end to our collective hunger for data, and so this must be fed by ever-larger, ever-denser data centres designed, powered and …

Intel raises memory deflector shields in Xeon E7 processor refresh

Intel has given its Xeon E7 processor family its annual refresh, this time emphasising analytics at scale. The new E7-8800/4800 v3 chips use the Haswell micro-architecture, meaning all Chipzilla's Xeons have made the jump. Intel's been a bit cagey, and did not share the list of E7 v3 models as we were going to press, but we' …

The data centre design that lets you cool down – and save electrons

I started my commercial data centre experience in London in the late 1990s. Even back then, most of the service providers were parroting the same mantra: “Your power provision is limited, and we'll charge you through the nose for anything over the basic consumption figure you've signed up to.” The logic most of them gave was …

Green your data centre – without ending up in the Job Centre

Going Green: Tactics (Part 2) Data centres are big, noisy places that seem to have an emphasis on generating heat and making lots of bright lights flash. The first time you visit one, you'd be forgiven for thinking that the service provider's emphasis was on anything but the green credentials. And of course you'd occasionally be quite right: there are DCs …
