Thomas Sterling’s ISC 2016 Closing Keynote

Jun 23, 2016 |

Capturing the sparkle, wit, and selective skewering in Thomas Sterling’s annual closing ISC keynote is challenging. This year was his 13th, which perhaps conveys the engaging manner and substantive content he delivers. Like many in the room, Sterling is an HPC pioneer as well as the director of CREST, the Center for Research in Extreme Scale Technologies, Indiana University. Read more…

South Africa Team Claims Third ISC Student Cluster Championship

Jun 23, 2016 | At an awards ceremony held yesterday at ISC 2016 in Frankfurt, Germany, a roar of applause filled the auditorium as Team South Africa took to the stage to collect their third HPCAC-ISC Student Cluster Competition championship prize from HPC luminary Thomas Sterling. "I have to say that this is extraordinary," said Sterling, who was helping to officiate along with Gilad Shainer (of Mellanox). Read more…

Around the HPC World in 81 Slides with IDC

Jun 21, 2016 | IDC presented its annual HPC Update at ISC yesterday. As usual it was a whirlwind tour encompassing HPC market data, technology trends, new IDC initiatives, announcement of the ISC16 Innovation Award recipients, and an update on IDC's DOE-funded study to demonstrate HPC’s ROI.

Intel Launches ‘Knights Landing’ Phi Family for HPC, Machine Learning

Jun 21, 2016 | From ISC 2016 in Frankfurt, Germany, this week, Intel Corp. announced that its new Xeon Phi product family, formerly code-named Knights Landing, is now shipping for high-performance computing and machine learning workloads. The company had been shipping to early customers for the last six months and was waiting to ramp up production before making the product generally available. The window also gave OEMs time to complete their readiness, said Intel's Charlie Wuischpard. Read more…

HPE Tackles Phi, Debuts Mfg. Solution and New HPC Software Environment

Jun 20, 2016 |

Hewlett Packard Enterprise (HPE), now about eight months into its transition as a separate entity, retained the prestige of fielding the most systems of any vendor on the Top500 list announced at the ISC2016. HPE had 127 systems (25.4 percent) though the number was down from 155 just six months ago. Other ISC news included introduction of a vertical solution for manufacturing developed with ANSYS, announcement of expanded use of Intel (Knights Landing, Omni-Path) and Mellanox (EDR) technology, and the unveiling of a new HPE software environment for HPC.

Baidu Researcher Pushes GPU Scalability for Deep Learning

Jun 20, 2016 | Greg Diamos, senior researcher, Silicon Valley AI Lab, Baidu, is on the front lines of the reinvigorated frontier of machine learning. Before joining Baidu, Diamos was in the employ of NVIDIA, first as a research scientist and then an architect (for the GPU streaming multiprocessor and the CUDA software). Given this background, it's natural that Diamos' research is focused on advancing breakthroughs in GPU-based deep learning. Ahead of a paper he is presenting at the 33rd International Conference on Machine Learning, Diamos answered questions about his research and his vision for the future of machine learning. Read more…

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…
