How Lawrence Livermore Is Facing Exascale Power Demands

Jun 9, 2016 | The old adage “you cannot improve what you do not measure" is fresh again in the age of ubiquitous data. When considering the challenges of exascale computing, power is right at the top of the list and the major leadership-class centers want to make sure they're doing everything they can to manage the demands of power today - which can run as high as 10 MW at peak for the largest machines - and in the coming exascale era, when the number could be three times that high. At loads of this magnitude, the largest HPC facilities need to have all the relevant power data within arm's reach. Read more…

Alces Tries Flight on AWS and Life as an HPC SaaS Provider

Jun 9, 2016 | Today, the community of HPC-in-the cloud solution providers is fairly limited. Giant hyperscalers – notably Amazon (AWS), Google (GCP) and Microsoft (Azure) – remain at the core and keep expanding their HPC resources. Circling around them are HPC ‘services specialists’ plugging clients into cloud providers and striving to ease delivery of HPC-in-the cloud to make good on the promise of improved efficiencies and cost reductions. Last week a new HPC Software as a Service (SaaS) player popped up on AWS marketplace – Alces Flight, a UK-based company with roots as an HPC integrator. Read more…

NITRD Proposed $4.5B Budget In the Spotlight

Jun 7, 2016 | Two weeks ago Rep. Darin LaHood, (R-Illinois), sponsor of the 2017 NITRD funding bill - The Networking and Information Technology Research and Development Program - issued a formal statement championing the proposed budget. NITRD, of course, is the nation’s primary source of federally funded work on advanced information technologies (IT) in computing, networking, and software... Read more…

Exiting Intel, James Reinders Offers a Brief Personal Retrospective

Jun 6, 2016 | You may have heard that Intel has encouraged “long timers” (like me) to consider early retirement. Well, the offer was convincing for me. After 10,001 days at Intel, it is time for me to start the next phase of my life. I've accepted the “ERP offer” (early retirement) with my last day being June 24, 2016 (exactly 10,000 days after my start date). I’ll be in the office as much as needed to help transitions and wrap things up. Let me know if you need/want anything from me as I finish up. Read more…

Testing the Waters of Liquid Cooling with Asetek ServerLSL

Jun 6, 2016 |

Trends in chipset wattage, rack density and the need for sustained un-throttled throughput have made it clear that liquid cooling will be a centerpiece for HPC data centers sooner rather than later.  HPC sites in particular are facing issues that purely air cooled servers and cutting edge air cooled data centers will be unable to address for high density HPC clusters.

In some cases, higher performance CPUs and GPUs packed into high density server racks exceed the ability of air flow to provide sufficient cooling. Read more…

TACC Director Lays Out Details of 2nd-Gen Stampede System

Jun 2, 2016 | With a $30 million award from the National Science Foundation announced today, the Texas Advanced Computing Center (TACC) at The University of Texas at Austin (UT Austin) will stand up a second-generation Stampede system based on Dell PowerEdge servers equipped with Intel "Knights Landing" processors, next-generation Xeon chips and future 3D XPoint memory.

Mellanox Spins EZchip/Tilera IP Into BlueField Networking Silicon

Jun 1, 2016 | Mellanox today introduced the BlueField family of programmable processors, the first product technology based on its $811 million acquisition of fellow Iraeli high-tech company EZchip. The fact that the product announcement is taking place just three months after the completion of the purchase speaks to the strong synergies between EZchip and Mellanox, said Bob Doud, senior director of marketing at Mellanox.

Cavium Unveils ThunderX2 Plans, Reports ARM Traction is Growing

May 31, 2016 |

Cavium yesterday rolled out plans for ThunderX2, the next generation of its ThunderX line of ARM system-on-a-chip (SOC) processors. Given all of the recent noise around Intel’s Broadwell and Knights Landing chips, the announcement is a reminder that the ARM camp continues to make what it believes is steady progress into the x86-dominated landscape. Cavium made the announcement at Computex being held this week in Taipei. Read more…

Univa Expands Grid Engine Support for Docker and Intel KNL

May 31, 2016 | Univa today announced general availability of Grid Engine 8.4.0. The latest version of Grid Engine includes many new features including expanded support for Docker containers as well as “preview support” for Intel’s latest Xeon Phi code named Knights Landing processor. Univa also reports fixing more than 80 prior issues. Leading the container enhancements, users can now automatically dispatch and run jobs in Docker containers, from a user specified Docker image.

Intel Announces New Knights Landing Book

May 30, 2016 |

“The fact is that Intel has aggressively decided to build a new kind of processor, which includes a number of advances that make it not only the most scalable processor the world has ever seen, but also one of the most versatile, configurable and highly integrated CPUs ever devised,” explains James Reinders as he describes the upcoming Intel® Xeon Phi™ processor.

With that kind of accolade for the forthcoming processor, you wouldn’t be surprised to hear that James and two other Intel experts—Jim Jeffers and Avinash Sodani—have written a book about it called Intel Xeon Phi Processor High Performance Programming: Read more…
