Leeds Testing Iceotope Liquid Server Cooling Technology

Staff — Sat, 02 Mar 2013 15:47:22 +0000

A revolutionary liquid-cooled computer server that could slash the carbon footprint of the internet is being tested at the University of Leeds.

While most computers use air to cool their electronics, all of the components in the new server are completely immersed in liquid. The power-hungry fans of traditional computing are replaced by a silent next-generation liquid-cooling process that relies on the natural convection of heat.

But the significance of the new Iceotope server lies less in the novelty of its design than in the bite it could take out of the huge electricity demands of the internet servers that form the fabric of our online lives. Its designers calculate that the server cuts energy consumption for cooling by between 80 percent and 97 percent.

A 2011 report by Datacenter Dynamics estimated that the world’s data centres currently use 31 gigawatts of power, the equivalent of about half of the UK’s total peak electricity demand. A 2008 report by McKinsey and Company projected that data centre carbon emissions will quadruple by 2020 and a year-long investigation by the New York Times, published in September, criticised the industry for its energy waste.

UK company Iceotope designed and built its new server working with team of researchers led by Dr Jon Summers from the University of Leeds’ School of Mechanical Engineering. The first production system has now been installed at the University after two years of testing prototypes.

Dr Summers, whose team used computational fluid dynamics to model how the coolant flows through the new server’s components, said: “The liquid we are using is extraordinary stuff. You could throw your mobile phone in a tub of it and the phone would work perfectly. But the important thing for the future of computing and the internet is that it is more than 1,000 times more effective at carrying heat than air.”

Adaptive Computing Taking Scientific Visualization to New Heights

Staff — Wed, 06 Feb 2013 16:58:02 +0000

In this special guest feature from Scientific Computing World, Chad Harrington, VP of marketing at Adaptive Computing, reflects on visualization workloads.

It doesn’t take a pair of rose-coloured aviator glasses to visualise this scenario: imagine you’re an aerodynamics engineer and you’re scanning a 3D simulation of your latest concept plane. You pan, zoom and otherwise manipulate the simulation that visualises airflow around the wings and fuselage. The simulation is massively pixilated and highly compute-intensive, and yet you’re viewing and manipulating it on a three-year-old laptop. What’s more, several of your colleagues are on a conference call with you, and they’re manipulating those same pixels in the same session from multiple locations using typical office PCs and even tablets.

The fact is that this scenario is a reality in leading-edge visualization environments today. That’s because an integrated solution consisting of HPC workload management software and visualization software is doing for 3D simulation workloads what Software as a Service did for 2D applications: keeping applications and data together on the server side where they can be accessed simultaneously by multiple PCs, thin clients and mobile devices on the same session. And compute resources can be used more efficiently than ever before.

For IT managers, visualization workload optimization couldn’t arrive sooner. That’s because today it’s not unusual for 3D simulations to top out at 50 gigabytes or more. Worse still, they’re getting bigger every year and workload management issues are following suit. Workstations are becoming obsolete faster than ever before – usually in less than three years – and, of course, licensing, troubleshooting, patching and updating requirements at widely dispersed offices and desks are costly, time-consuming hassles. Network congestion and latency are serious issues, too, as is leakage of proprietary data.

Upfront workstation costs also continue to be a key concern. Deskside workstations feature high-end CPUs, top-of-the-line GPUs, and lots of memory. And they are single-purpose machines. Once a simulation is up and running, the system’s usefulness is tapped out. Adding insult to injury, workstations must be sized for the largest potential simulation job. So, even if small- or mid-sized technical visualization sessions are the norm, the workstation must be overbuilt to handle the worst-case scenario. Given today’s widely dispersed and mobile workforce – and the need for elasticity when it comes to compute and network resources – the immovable and otherwise rigid deskside workstation is an idea that’s gone the way of the zeppelin.

Instead of having expensive hot, loud, underutiliszed workstations taking up space under desks, it makes sense to have 3D CAD/CAE and other scientific visualization applications and data housed on shared virtualization clusters. Users get the full power of a high-end, GPU-enabled machine – as if it’s under their desks – while GPUs and other high-performance compute resources are shared by multiple sessions.

In addition, compute capabilities can be ‘right-sized’ on the fly, and utilization can be maximised. Rather than clogging networks by transferring source data for full workloads, this approach minimises bandwidth use. Likewise, support, updating and replacement of hardware and software are more efficient, less costly processes that do not affect users nearly as much as when those processes are completed at individuals’ desks. And by keeping data sets closer to the centralised resources, you can minimise security risks by ensuring tighter access control and data security.

Perhaps the most important benefit, however, is the ability to share these visualizations anywhere, using virtually any computing device. Users are able to securely work where it makes the most sense – in conference rooms, at home after work or wherever they are authorised to do so. As a result, workforce collaboration and productivity can improve dramatically.

Adaptive Computing, the largest provider of private cloud management and high-performance computing (HPC), has recently added two versions of its Moab HPC Suite that make these capabilities possible. Moab HPC Suite Application Portal Edition and Remote Visualization Edition are designed to maximise backend processing efficiencies and leverage next-generation access models. By simplifying the collection and interpretation of data, these solutions can help reduce the time it takes to achieve meaningful results.

Many companies have major investments in HPC in the data centre, and, generally, those resources aren’t used at anywhere near capacity. The same can be said for visualization workstations that are dispersed throughout many companies. But the good news is that those resources can now be brought together in a private technical compute cloud that handles both HPC and visualization. In many cases, GPUs can be shared between computational and visualization workloads – dedicated to visualization workloads during the day and HPC computational requirements through the night. HPC workload management software policies can be put in place to automatically determine which sessions and jobs go where. Those policies can also be set up to establish reservations for higher-priority workloads at specified times of the day or night.

Radio Free HPC on the First Rule of Exacale: Do Not Talk about Exascale

Rich Brueckner — Tue, 29 Jan 2013 12:30:36 +0000

In this episode of Radio Free HPC, the topic of Exascale is under the hosts’ scrutiny once again as they discuss some interesting stories released by The Exascale Report featuring opinion by Bill Gropp of NCSA and Bill Harrod of DOE.

Rule #1: You do not talk about Exascale. (Kind of like rule #1 of Fight Club, except the guys keep breaking it.) Why not? Because too many of the people talking about Exascale are having the wrong conversation about it.

What should the conversation be? Should it be about the systems themselves, or about the work that can be done only with those systems — the science that we can’t yet do? Spoiler alert: Dan and Henry disagree on this. But a peaceful vibe reigns once again as they discuss what The Exascale Report calls “The Three Noble Truths” of Exascale, which sounds kind of Zen and cool — as if it was coined by Exascale Samurai.

And finally… is it time to talk about Zetta-scale?

Nvidia Wins $20 Million DARPA Contract

Staff — Fri, 04 Jan 2013 16:09:15 +0000

Nvidia has been awarded a contract worth up to $20 million from the Defense Advanced Research Projects Agency (DARPA) to research embedded processor technologies that could lead to dramatic improvements in the ability of autonomous vehicles to collect and process data from onboard sensors.

DARPA is the US Defense Department’s research and development arm. The five-year contract, awarded under DARPA’s Power Efficiency Revolution For Embedded Computing Technologies (PERFECT) programme, will fund research for processors that are 75 times more energy-efficient than current embedded solutions.

The goal is to enable surveillance and computer vision systems in ground and airborne vehicles to collect and analyse much more data than can be processed today in real time.

Existing embedded processors deliver about one gigaflop of performance (one billion floating point operations each second) per watt. The Nvidia programme, known as Project Osprey, will research low-power circuits and extremely efficient architectures and programming systems that enable 75 gigaflops per watt.

The technologies developed with this program can transform the capabilities of embedded systems, making autonomous vehicles more practical and intelligent,’ said Steve Keckler, senior director of architecture research at Nvidia. “This research will help Nvidia continue to advance mobile computing for both government and consumer applications.”

European Mont-Blanc Project Selects Samsung Multicore ARM Processor

Staff — Thu, 06 Dec 2012 19:19:48 +0000

The Mont-Blanc European project has selected the Samsung Exynos platform as the building block for powering its first integrated low power-high performance computing (HPC) prototype.

The aim of Mont-Blanc project is to design a new type of computer architecture capable of setting future global HPC standards, built from today’s energy efficient solutions used in embedded and mobile devices.

The Samsung Exynos 5 Dual is built on 32nm low-power HKMG (High-K Metal Gate), and features a dual-core 1.7GHz mobile CPU built on ARM Cortex-A15 architecture plus an integrated ARM Mali-T604 GPU for increased performance density and energy efficiency. It has been featured and market proven in consumer and mobile devices such as Samsung Chromebook and Google’s Nexus 10.

This will be the first use of an embedded mobile SoC in HPC, which enables the Mont-Blanc project to explore the challenges and benefits of deeply integrated energy-efficient processors and GPU accelerators, compared to traditional homogeneous multicore systems, and heterogeneous CPU + external GPU architectures.

The Exynos 5 Dual packs the most powerful ARM processors with a programmable GPU in a low-power mobile device that would normally be in someone’s pocket and running on a battery. Its performance density, energy efficiency, and low market price make it an extraordinary building block for prototyping a new generation of HPC systems.’ said Alex Ramirez, coordinator of the Mont-Blanc project.

During the first year of activities, Mont-Blanc has focused on deploying successfully an HPC system software stack and full-scale scientific applications on ARM platforms, proving that ARM-based architectures are feasible alternatives for HPC. Now the efforts gear towards integration of the Exynos platform on a HPC solution, and software exploitation of the embedded GPU.

An Apps Store for HPC?

Rich Brueckner — Fri, 23 Nov 2012 15:10:35 +0000

Over at Computerworld, Patrick Thibodeau writes that easily available and affordable “Apps” are coming to HPC. In the mobile space Apps tend to be simple packages that do one thing very well. For HPC, an App would work the same way on a specific task, such as modeling and simulating the flow of a fluid through a pipe.

I think this can be the disruption to what’s been a pretty stagnant software world for the last decade,” said Tom Lange, Proctor & Gamble’s director of modeling and simulation, of the potential of apps. Lange believes that apps can help “democratize” HPC and make simulation analysis “an everyday part of decision-making.”

How would this work? Such an App model is already in place at NSF’s NanoHub.org, where researchers can get access to more than 250 codes. Read the Full Story.

Interview: Seeking Your Customers for HPC Innovation Excellence Awards

Rich Brueckner — Fri, 28 Sep 2012 16:46:15 +0000

Last year, IDC rolled out their HPC Innovation Excellence Awards designed to recognize noteworthy achievements in high performance computing. Nominations are due Oct. 22, 2012, so I caught up with IDC’s Chirag Dekate to learn more.

insideHPC: Why did IDC create Innovation Awards?

Chirag Dekate: The HPC Innovation Excellence Award Program was created to showcase success stories involving HPC across universities, research laboratories and industry. The program seeks to increase awareness of benefits of adopting HPC and justifying HPC investments across the user community, including emerging SMEs / SMBs. Through increased awareness of the quantified impact of HPC technologies and capabilities, regional, national and international funding agencies can better measure the socio-economic impact of HPC. The award program also facilitates garnering public support for continued visionary investment software, services and infrastructure towards performance and data-intensive oriented computing.

insideHPC: Why do you think that HPC ROI has been so difficult to quantify?

Chirag Dekate: We all know viscerally that HPC makes important contributions. From the weather forecasts that we check every morning to designing the automobiles that we drive every day, from consumer products like diapers and detergent container designs to aircraft engines, simulation driven by HPC and data intensive computing are seminal technologies that impact almost every single aspect of our daily lives. But finding a large number of quantified examples of ROI from HPC has been really difficult. Some HPC users don’t track their ROI from HPC, and others need help with quantifying ROI from information on hand. The Innovation Excellence Award Program was designed to identify a larger number of quantifiable success stories and to help successful users to quantify their achievements as needed. .

insideHPC: Can you tell us about some of the past winners and what set them apart?

Chirag Dekate: Past winners of the HPC Innovation Excellence Award include a broad spectrum of end users and technology developers across multiple verticals throughout the world. The DOD HPC Modernization program has won multiple awards for their innovative application of high performance computing in several critical scenarios such as virtual prototyping of countermeasures and more. The Beijing Genomics Institute won awards for the breakthrough application of HPC technologies to accelerate the innovation and commercialization of genomic solutions. Several national laboratories and supercomputing centers including LLNL, NERSC, the Ohio Supercomputing Center, the Shanghai Supercomputing Center, CDAC, Cornell University CAC, and others have won recognition for their efforts in broadening the impact of HPC technologies.

All of the simulations demonstrated one or more of these criteria: economic impact, acceleration of key industrial and simulation processes, and more. IDC worked with several application candidates to develop ROI narratives based on econometrics and market impact.

insideHPC: What makes for a good submission?

Chirag Dekate: Many users of high performance computing and data intensive computing have important stories to tell. But the achievements have to be both impressive and quantified. In some cases it is easy to develop ROI quantifications, as the economic impact is relatively obvious. In other cases, IDC works with the candidates to determine the economic impact of the technologies. We’re a research organization, and we can often relate their achievements to other research data we’ve created or have access to.

insideHPC: When is the next round of submissions and awards?

Chirag Dekate: The award program accepts submissions year-round. Nominations can be submitted through the HPC Innovation Excellence Award Website. The awards winners are announced around the two major supercomputing conferences – International Supercomputing Conference (June) and the Supercomputing Conference (November). The deadline for the upcoming round of submissions for the HPC Innovation Excellence Award is October 22, 2012. Winners will be announced at the IDC Breakfast Briefing at the Supercomputing Conference, on November 13, at the Hilton Salt Lake City.

In this video, Alex Ramirez from the Universitat Politècnica de Catalunya presents: The Mont-Blanc Approach Towards Exascale.

During the 90′s, microprocessors killed the vector supercomputers as soon as they implemented the required features for HPC due to their lower costs and higher energy efficiency. Nowadays, we may be ready to take the next step and see how embedded processors , which are implementing the required features for HPC, may kill microprocessors due to their lower cost and higher energy efficiency. The Mont-Blanc project leads a new approach towards energy efficient supercomputers based on mobile and embedded technologies.”

DARPA Sees UPSIDE of Analog Computing

Rich Brueckner — Mon, 27 Aug 2012 15:36:11 +0000

Over at Wired Magazine, Robert McMillan writes that DARPA is funding a new program called UPSIDE that will investigate analog computing as a means of achieving better power efficiency. The idea is to have chipmakers build analog processors that can do probabilistic math without forcing transistors into an absolute one-or-zero state, a technique that burns energy.

Darpa’s 54-month program will run in two phases. During the first companies will build chips using probabilistic techniques. During the second, they will build mobile imaging systems using the chips. Hammerstrom expects the systems to be faster and “orders of magnitude more power-efficient.”
