Intel’s new 18-core Haswell Xeon chips will try to preempt the ARM server onslaught

Intel Xeon E7 Ivy Bridge-EX die (15 core)


Intel has released a new batch of Xeon chips — the Xeon E5 v3 range – and by all accounts it’s the most impressive set of server products the company has shipped in years. While these new chips are based on the now-familiar Haswell core, they aren’t just retreads of existing silicon — Intel has pushed core counts all the way up to 18 cores per socket, integrated sophisticated new Turbo mechanisms, added new forms of cache monitoring, moved its entire platform over to DDR4, and can individually gate each CPU core for maximum power savings.

With up to 45MB of L3 and a dual ring bus that uses multiple interfaces to maximize inter-chip bandwidth, the Xeon E5 v3 (Haswell-EP) lineup is a truly formidable slice of silicon. Tech Report reports (sorry) that Intel has even implemented a cluster-on-die option that gives users more fine-grained control over which domain threads execute within (Intel reports single-digit performance gains in some cases from fine-tuning the chip in such fashion).
Combine the new features and higher core counts, and the Haswell-EP family tears through its own predecessors, exceeding performance on Xeon parts just a year old by as much as 20%.

The gains don’t apply in every scenario or situation — much as we saw with Haswell-E, there are cases where higher core clocks and smaller thread counts carry the day. What I find most interesting about the hardware, however, is the way that Intel is clearly moving to shore up its enterprise divisions against the oncoming ARM server push.

Locking up the high end

Calxeda may have collapsed but it’s not the only ARM server company looking to make a name for itself. AMD has its own ARM products set to deploy in 2015 with a custom ARM core following in 2016. The newcomer Cavium is prepping its ARM-based ThunderX core, and there are rumors that Google and Facebook might build custom servers of their own. AppliedMicro’s X-Gene is also finally set to start shipping on 28nm (40nm parts are already available).
None of these parts are a threat to Intel’s server business as it exists today — in fact, they all face substantial scaling challenges and a dire need for ecosystem development that will limit sales and shipments in the first few years. All the price/performance advantages in the world don’t mean much if a new CPU doesn’t support the full range of software that needs to run on it, and Intel is fully aware of it.
Just because ARM poses no serious threat in 2015-2016, however, doesn’t mean it couldn’t be facing a longer-term strategic competitor — and that’s one reason why Intel is migrating what used to be EX-class features and capabilities into the more mainstream EP segment. (The photo at the top of the story, incidentally, is 15-core Xeon E7 Ivy Bridge-EX chip.)
Haswell-EP
The new Haswell-EP ring bus design and core counts
The reason I think it’s fair to judge these new Haswell-EP parts as part of Intel’s opening gambit against an ARM threat is that the server market tends to move more slowly and deliberately than desktop or consumer spaces. Tablet market share can change in a matter of months if a particularly popular Android or iOS device launches, but workstation and enterprise server deployments tend to be long-term affairs. With its huge set of new SKUs and capabilities, Intel has launched a series of parts that dares up-and-coming players to try and match them.
It’s a daring move. Rather than simply retrenching and fighting on clock speed or core count, the Haswell-EP family is designed to stretch from low-power, high-efficiency cores to massive 18-core monsters — and all of this is on the midrange server platform.
If Intel’s strategy works, it won’t keep ARM products from gaining any market share at all — but it could end up confining them to the less profitable segments of the market — just as Chipzilla successfully confined AMD more than ten years ago.

The Smart Home Is Going To Be A Huge Boon To Accessibility

The Smart Home Is Going To Be A Huge Boon To Accessibility
I reach for the iPhone tucked down the side of my wheelchair and launch the Hive app. After a couple more taps on the screen, there’s an audible click from across the room. A few seconds later, I hear the boiler sparking up before the central heating finally kicks in. It’s a familiar sound, but this time the experience is profoundly different.
I break out in a smile knowing that I will never again need to take a stick and whack the boiler’s out-of-reach array of switches each time I want to override the central heating schedule or adjust its settings. Nor will I have to ask somebody else to operate the central heating for me. The future is here and it just got a little more evenly distributed.
The smart home — which at its most basic is enabling various devices around the home, such as thermostats, lighting and door locks, to be connected to the Internet and controlled via a smartphone — is going to be a huge boon to accessibility. However, like a lot of technology before it, this vision of the future has been prohibitively expensive (and often overly complex), putting it beyond the reach of many, including people like me who have a physical disability and for whom smart home technology could potentially make the most difference. That’s starting to change.
More recently, a raft of new smart home products have been coming to market, both from traditional consumer electronics companies and startups alike, helped by the rise in crowdfunding via platforms like Kickstarter and IndieGoGo. Unlike the uber smart home systems traditionally sold by smart home specialists, however, these new generation of products tend to take a small pieces, loosely joined approach that makes it easier (and cheaper) to dip a toe in the smart home waters.
The disadvantage, of course, is that discrete devices, by their very nature, don’t always talk to one another, requiring a separate app each to operate, and aren’t nearly as smart as they could be. But that too is changing.
For iOS users, Apple has unveiled HomeKit, its own (somewhat locked down) platform for integrating third-party smart home devices, letting them interact with each other, as well as with Apple’s Siri.
Google-owned Nest is also opening up through its “Works with Nest” developer program, which positions the company’s Nest Learning Thermostat as the hub of the smart home, enabling other apps and devices to utilise the smart thermostat’s motion sensor and feed into its self-learning capability.
Others vying to become a smart home standard are Quirky’s Wink, and Samsung-acquiredSmartThings. The Internet of Things ‘recipe’ service IFTTT is also doing a good job at providing some level of interoperability between disparate smart devices.
It’s still early days, however, and this is reflected in the cobbled-together nature of my own smart home setup. It currently sports a Hive smart thermostat from British Gas, two sets of smart lightbulbs from Philips and LIFX, a Belkin smart plug and motion sensor, and an Apple AirPlay-enabled home audio system.
But, while my approach has been tentative so far, I’ve already experienced enough first-hand to know that, just like other enabling technology before it, the smart home has the potential to change my world for the better.

British Gas Hive Active Heating

Hive Active Heating is a smart thermostat from UK energy household name British Gas, with technology provided by AlertMe. The device replaces your existing thermostat and boiler switch, enabling your home’s central heating to be programmed and controlled via the excellent Hive iOS and Android smartphone apps, or the Hive website.
theappCommands are actually sent via the cloud, so require the Hive system to be permanently connected to the Internet in addition to your home’s WiFi network. However, this also means you’re able to toggle your heating even when you are away from home, which is especially convenient on a freezing British winter’s night.
More recently, British Gas has added geo-location features to alert you if you accidentally leave the heating on when leaving the house or if you’re returning home and the temperature is set lower than you find comfortable.
On the downside, Hive Active Heating doesn’t feel especially smart, at least not compared to other smart thermostats on the market. Here I’m thinking of Nest’s self-learning algorithms that help it understand how long your home takes to heat up in various weather conditions, or Tado’s geo-fencing functionality that means it can be set to automatically switch on your heating as you approach home.
There’s no open API yet either, meaning that other smart home devices and apps can’t interact with Hive, though I’m hopeful this will change in the future. However, none of the above takes away from Hive’s accessibility credentials; being able to control the central heating via my laptop and smartphone has been truly empowering.
Pros
  • Well-designed apps for iOS, Android and web.
  • Control your central heating and hot water when you are away from home.
  • Unlike competitors, Hive Active Heating includes free installation from a qualified British Gas engineer.
  • Doesn’t over-rely on the use of the Hive apps but reassuringly includes physical controls on the Hive thermostat itself.
Cons
  • Consists of three separate hardware components: a hub, receiver, and thermostat.
  • Not especially smart and no API for integration with third-party apps.

Philips Hue

Philips Hue is a ‘connected’ lighting system that comprises various LED-based colour-changing lightbulbs and other lighting products, which can be controlled over your local WiFi network and, optionally, the cloud. Like Hive, the Hue’s main accessibility draw is the ability to adjust your home’s lighting via a smartphone.
My setup consists of a Hue starter kit (see our full review), providing three LED multicoloured lightbulbs, and the required Hue hub, which can talk to up to 50 bulbs on the same local area network. This lets me use my iPhone to switch any of the three Hue bulbs — two in the lounge and one in the hallway — on and off, along with adjusting their intensity and colour. The latter feels a tad gimmicky at first but soon becomes a great way of changing up the atmosphere of a room, which is especially useful as somebody who works predominantly from home.

There’s one accessibility caveat, however: If someone turns the lights off at the existing wall switch, the corresponding Hue lightbulbs no longer receive power and are therefore temporally disconnected from the network and can’t be controlled by the Hue app. This isn’t an issue specific to Philips Hue, but is common across almost all connected lighting solutions. Nonetheless, until you retrain your household’s collective muscle memory, be prepared to lose that new-found independence at the flick of a switch.
The other major plus of Hue is its growing ecosystem, which is already seeing an increasing number of third-party apps and services add support for Philips’ connected lighting. This means, for example, that you aren’t stuck using the official iOS and Android app, which is just as well since it’s overly complex and not particularly intuitive.
Pros
  • Set up was super quick and easy, even if I wasn’t keen on putting yet another hub in my living room.
  • Nice looking bulbs.
  • Excellent developer support, resulting in a plethora of third-party apps and service integration.
  • Control you bulbs over the cloud so you can make it look like someone is home even when they aren’t.
Cons
  • Overly-complex and unintuitive official app.
  • At only 600 lumens, the Hue connected lightbulbs could be brighter.
  • Doesn’t come in bayonet versions, thus requiring an adaptor for use in most British households.

LIFX

Startup LIFX is a direct competitor to Phillips Hue, and offers a similar accessibility proposition: theability to control your home’s lighting via smartphone apps and the cloud. However, unlike Hue, the LIFX connected bulbs don’t require a separate hub and, instead, connect directly to your home WiFi network. As a result, they are more expensive per bulb, but have less upfront cost, since you don’t need to purchase a starter kit but can begin with a single bulb.
Bulb_Resting_White_B
A few other noticeable differences compared to Hue: The LIFX bulbs are considerably brighter, running at a maximum of 1,017 lumens, and colours seem more vibrant, which may be important depending on your take on multicoloured lighting. The official LIFX app for iOS and Android is also a lot more intuitive than Philips Hue.
However, third-party support and the platform as a whole feels less mature, although this is steadily improving. The LIFX bulbs themselves are pretty bulky, too, and can run rather hot at times.
Pros
  • At around 1,000 lumens, LIFX bulbs are significantly brighter than Hue.
  • Intuitive app for iOS and Android.
  • Doesn’t require a hub.
Cons
  • Bulbs are bulky and may suit a longer lampshade depending on your current setup.
  • Third-party support isn’t as widespread as Hue.
  • Expensive per bulb, despite a cheaper entry cost.

Belkin WeMo Switch + Motion

372.jpg-3The Belkin WeMo Switch + Motion is my first foray into home automation, rather than making the home smarter simply by being connected. It consists of two hardware components: a WiFi-enabled power plug/outlet, and an accompanying motion sensor, which can be placed somewhere else in the home.
The former lets you turn devices on and off via the WeMo Switch and app, providing a similar accessibility advantage as the other smart home devices. The latter, meanwhile, goes one step further, and enables devices to be switched on and off based on motion, such as people entering and exiting a room, together with other rules, like time of day — all programmed via the very intuitive WeMo app.
While I haven’t quite figured out the ideal accessibility use case for motion detection, one example I’ve played with is having a fan come on and off depending on whether or not anybody is in the room. By combining IFTTT, which WeMo supports, you could also, theoretically, set a rule that adjusts this behaviour based on local weather conditions, too. If the outside temperature is low, don’t switch on the fan regardless of any motion detected.
Pros
  • Very easy to install and configure.
  • Intuitive iOS and Android app, and rule-based system.
  • Support for IFTTT, extending the possibilities of basic home automation.
Cons
  • The Belkin Switch is quite bulky and may not allow for another device to be plugged in side-by-side on a typical UK twin power outlet.
  • Expensive to get started.

Apple’s AirPlay

Apple’s AirPlay technology, which lets compatible devices stream audio (and video and photos) to each other, should probably count as the start of my smart home journey, although I didn’t know it at the time.
airfoil-mainThrough the combination of an iPhone, iMac, Airport Express WiFi adaptor, and the excellent AirFoil app, I’m able to stream and control music from my smartphone or computer to two separate home audio/speaker setups in the lounge and bedroom/home office, respectively. This includes music stored in iTunes, and other sources, such as Spotify running on my laptop.
Once again, the accessibility advantage is the ability to remotely control my digital music collection and connected home audio system via an app.
Pros
  • Mostly it ‘just works’.
  • Widespread support on iOS.
  • Lots of AirPlay-compatible connected speakers on the market.
Cons
  • One of a number of competing media streaming standards, so support isn’t as ubiquitous as it could be.
  • Apple’s AirPort Express is expensive, though there are cheaper third-party alternative AirPlay-compatible WiFi adaptors available.

WHAT’S NEXT?

The burgeoning smart home currently means different things to different people. As it stands, for a device to qualify as being ‘smart’ it simply needs to be connected, either locally and/or via the cloud — and this alone provides greater accessibility. However, over the next few years, the smart home is going to become a lot smarter by making better use of data and increasing integration between devices and platforms, with the end-goal being home automation.
Right now, smart home devices tend to give you a lot of control but require far too much intervention; as my colleague Natasha Lomas says, an app for everything is not particularly smart or liberating. In contrast, the idea behind home automation is to have the home take care of you, rather than you needing to take care of it.
This could be anything from blinds automatically opening and closing, based on factors such as time of day, ambient lighting or weather conditions, or the lamp in your home office coming on as you approach your desk, via the use of Beacon technology (an idea I’m going to explore after recently backing Airfy’s successful Kickstarter campaign).
In fact, with a new generation of smart home devices coming to market that pack an array of sensors, from motion or proximity detection, to something that measures air quality, the possibilities of home automation are going to become almost limitless. And it’s not hard to see how that future could further improve accessibility and the lives of people with disabilities. Or anybody else, for that matter. Just how I like it.
