China Debuts 93-Petaflops ‘Sunway’ with Homegrown Processors

Jun 19, 2016 |

You may have heard the rumors, but now it’s official: China has built and deployed a 93 petaflops LINPACK (125 petaflops peak) Chinese-made supercomputer at its Wuxi Supercomputer Center, near Shanghai. A few days ago HPCwire received an advance copy of a report on the new system prepared by TOP500 author Jack Dongarra detailing the feeds and speeds and proffering perspective on its strengths and weaknesses.

NVIDIA Debuts PCIe-based P100; Broadens Aim at CPU Dominance

Jun 19, 2016 |

NVIDIA seems to be mounting a vigorous effort to dethrone the CPU as the leader of the processor pack for HPC and demanding datacenter workloads. That’s a tall order. Introduction at ISC 2016 of a PCIe-based version of is new Tesla P100 card is one element in the strategy. It should ease the upgrade path for many. But really, NVIDIA’s mantra has been shifting since introduction of the Pascal chip and DGX-1 platform last April. Read more…

What Knights Landing Is Not

Jun 18, 2016 |

As we get ready to launch the newest member of the Intel Xeon Phi family, code named Knights Landing, it is natural that there be some questions and potentially some confusion.

I have found that everything is clear, when we really understand that Knights Landing is an Intel processor. That makes it NOT Knights Corner. That makes it NOT a GPU. Read more…

Offloading vs. Onloading: The Case of CPU Utilization

Jun 18, 2016 |

One of the primary conversations these days in the field of networking is whether it is better to onload network functions onto the CPU or better to offload these functions to the interconnect hardware.

Onloading interconnect technology is easier to build, but the issue becomes the CPU utilization; because the CPU must manage and execute network operations, it has less availability for applications, which is its primary purpose. Read more…

Mellanox Advances ‘In-Network Computing’ with ConnectX-5 Adapter

Jun 16, 2016 | Networking specialist Mellanox has announced ConnectX-5, the next-generation of its 100G InfiniBand and Ethernet adapter line. The company says the new device will help organizations take advantage of real-time data processing for high performance computing (HPC), data analytics, machine learning, national security and ‘Internet of Things’ applications. ConnectX-5 was designed to connect with any computing infrastructure - x86, Power, GPU, ARM, and FPGA - and it employs a variety of offload engines, which can be classified into two camps.

Heading into ISC16, OpenHPC Releases Latest Stack with 60-plus Packages

Jun 16, 2016 | SC15 was sort of a muted launch party for OpenHPC – the nascent effort to develop a ‘plug-and-play’ software framework for HPC. There seemed to be widespread agreement the idea had merit, not a lot of knowledge of details, and some wariness because Intel was a founding member and vocal advocate. Next week, ISC16 will mark the next milestone for OpenHPC, which has since grown into a full-fledged Linux Foundation Collaborative Project and today released version 1.0.1 of OpenHPC (build and test tools).

Paul Messina Shares Deep Dive Into US Exascale Roadmap

Jun 14, 2016 | Ahead of ISC 2016, taking place in Frankfurt, Germany, next week, HPCwire reached out to Paul Messina to get an update on the deliverables and timeline for the United States' Exascale Computing Project. The ten-year project has been charged with standing up at least two capable exascale supercomputers in 2023 as part of the larger National Strategic Computing Initiative launched by the Obama Administration in July 2015.

OpenACC Adds Support for OpenPOWER; Touts Growing Traction

Jun 13, 2016 | In a show of strength leading up to ISC the OpenACC standards group today announced its first OpenPOWER implementation, the addition of three new members – University of Illinois, Brookhaven National Laboratory, and Stony Brook University – and details of its expanding 2016 training schedule. Michael Wolfe, technical director of OpenACC, also talked with HPCwire about thorny compiler challenges still remaining as... Read more…

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…
