Cray System to Help Steward Gulf After Deepwater Horizon

Today Cray today announced that the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE) will acquire a Cray XE6m supercomputer to help predict the fate of hydrocarbons released into the environment during normal and hurricane weather conditions. Funded funded by the Gulf of Mexico Research Initiative (GoMRI), CARTHE is a 10-year, […]

Video: Electronic-Photonic Integration within Switches and Routers

In this video, Michael R. Watts from MIT presents: Electronic-Photonic Integration within Switches and Routers. We review recent successes in silicon photonics and how the new capabilities afforded by silicon photonics will impact future Ethernet, Infiniband, and ultimately optical domain switches and routers. Specifically, we consider the impact silicon photonics can have on the cost, […]

OpenFabrics Workshop Comes to Zurich Sept. 24-25

The OpenFabrics Alliance will hold its the inaugural Zurich Workshop User Event September 24-25 in Rüschlikon. With the support of IBM Zurich Research, the OFA is pleased to bring this forum to OFS/OFED users in EMEIA, so that they may connect face-to-face and share knowledge with other users across the globe,” said Jim Ryan, Chairman, […]

Video: University of Hawaii Protests Loss of Supercomputing Contract

Keoki Kerr from Hawwii News Now reports that the University of Hawaii is protesting the loss of a lucrative contract to manage the Maui Supercomputer Center. The new contract could be worth as much as $70 million over the next 10 years. In its losing bid, UH partnered with defense contractor Lockheed Martin, which operates […]

Michael Wolfe on OpenACC Kernels and Parallel Constructs

Michael Wolfe from The Portland Group writes that OpenACC kernel constructs and parallel constructs are two ways to solve the same problem: identifying loop parallelism and mapping it to the machine parallelism. The kernels construct is more implicit, giving the compiler more freedom to find and map parallelism according to the requirements of the target […]

UPSCALE Project Awarded Record Supercomputing Time for Climate Modeling

The PRACE Partnership for Advanced Computing in Europe has awarded a record amount of supercomputer processing time to Prof. Pier Luigi Vidale and his UPSCALE project team. The UPSCALE project aims to increase fidelity of global climate simulations and our understanding of weather and climate risk, by representing fundamental weather and climate processes more completely. […]

Video: An Overview of the CAPS OpenACC Compiler

In this video, CAPS presents an overview of the OpenACC programming standard. They describe the main directives and provide a set of guidelines to get started with OpenACC, providing a set of concrete examples to illustrate the programming concepts. The OpenACC Application Program Interface describes a collection of compiler directives to specify loops and regions […]

Knights Corner Under the Hood

Over at SemiAccurate, Charlie Demerjian has posted an in-depth look at Intel’s Knights Corner from the recent Hot Chips conference. In the end, what you have is an unspecified number of cores, each grouped with an unspecified number of memory controllers, all running Linux. The world is reached with TCP/IP, and to the coder, it […]

Supercomputers Helped New Orleans prepare for Hurricane Isaac

Hurricane Isaac made landfall last night west of New Orleans, dumping over a foot of rain on the city. Over at Computerworld, Patrick Thibodeau writes that improved supercomputer modeling helped New Orleans plan better for the storm surge. In 2005, when Katrina landed, the capability to model storm surge, while good, may be rudimentary compared […]

Video: Adaptiva Epiphany-IV Outperforms x86 While Consuming Only 2 Watts

In this video, Yaniv Sapir from Adapteva demonstrates the the Epiphany-IV 28nm multicore silicon performance. The video shows how the Epiphany processor beats an x86 processor while executing a parallel matrix multiplication demo written entirely in ANSI-C. The Epiphany microprocessor architecture is a supremely scalable shared memory architecture, featuring up to 4,096 processors on a single […]
