Exascale Computing: The View from Argonne

June 21, 2012

As a result of the dissolution of DARPA's UHPC program, the driving force behind exascale research in the US now resides with the Department of Energy, which has embarked upon a program to help develop this technology. To get a lab-centric view of the path to exascale, HPCwire asked a three of the top directors at Argonne National Laboratory -- Rick Stevens, Michael Papka, and Marc Snir -- to provide some context for the challenges and benefits of developing these extreme scale systems.

HPC and the Spirit of St. Louis

June 20, 2012

Every year, as the International Supercomputing Conference in Germany approaches, our good friends here at HPCwire invite me to reflect on the trends of the past 12 months, not so much to provide a potentially tedious list of specific events, product deliveries, and TOP500 mantras but rather to convey a personal sense of what it all adds up to and possibly means for the future of HPC.

TOP500 Gets Dressed Up with New Blue Genes

June 19, 2012

The 39th TOP500 list was released today at the International Supercomputing Conference in Hamburg, Germany, with a new machine at the top. Sequoia, an IBM Blue Gene/Q machine, delivered a world record 16 petaflops on Linpack, knocking RIKEN's 10-petaflop K Computer into second place. The Japanese K machine had held the TOP500 title for a year. Read more…

Intel Will Ship Knights Corner Chip in 2012

June 18, 2012

On Monday at the International Supercomputing Conference in Hamburg, Intel announced that Knights Corner, the company's first manycore product, would be in production before the end of 2012. The company also released a few more details about the upcoming product line, including the creation of a new Xeon brand for the architecture, some performance updates on pre-production silicon, and Cray's adoption of MIC as part of its future Cascade supercomputer.

Mellanox Cracks 100 Gbps with New InfiniBand Adapters

June 18, 2012

Mellanox has developed a new architecture for high performance InfiniBand. Known as Connect-IB, this is the company’s fourth major InfiniBand adapter redesign, following in the footsteps of its InfiniHost, InfiniHost III and ConnectX lines. The new adapters double the throughput of the company’s FDR InfinBand gear, supporting speeds beyond 100 Gbps. Read more…

HPC Lists We’d Like to See

June 15, 2012

Since the release of the first TOP500 list in June of 1993, the HPC community has been motivated by the competition to place high on that list. We’re now approaching the twentieth anniversary of the TOP500. In recent years, two additional lists have gained traction: the Green500 and the Graph 500. Would a few more lists be useful?

Student Cluster Challenge Makes ISC Debut

June 13, 2012

For the first time in its history, ISC will host its first international Student Cluster Challenge (SCC), heretofore a mainstay of the US-based SC conference in November. Now the competition is moving far beyond its “fan favorite” origins to take center stage this June in an international venue. Read more…

The TOP500 Celebrates 20th Anniversary, Will it Survive 20 More?

June 12, 2012

With the upcoming release of the TOP500 next week, the latest rankings are usually a hot topic of discussion this time of year. Over the past 20 years, the list has proven to be a useful and popular compilation of supercomputers for the HPC community. In this exclusive interview, Professor Hans Meuer, considered by many to be the driving force behind the project, offers his thoughts on the TOP500; its past, present, and future. Read more…

End-to-End Support Toward Accelerating Discovery and Innovation with a Converged HPC and AI Supercomputer

A workload-driven system capable of running HPC/AI workloads is more important than ever. Organizations face many challenges when building a system capable of running HPC and AI workloads. There are also many complexities in system design and integration. Building a workload driven solution requires expertise and domain knowledge that organizational staff may not possess.

This paper describes how Quanta Cloud Technology (QCT), a long-time Intel® partner, developed the Taiwania 2 and Taiwania 3 supercomputers to meet the research needs of the Taiwan’s academic, industrial, and enterprise users. The Taiwan National Center for High-Performance Computing (NCHC) selected QCT for their expertise in building HPC/AI supercomputers and providing worldwide end-to-end support for solutions from system design, through integration, benchmarking and installation for end users and system integrators to ensure customer success.
