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.

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/Blue_Gene_Q_small.jpg” alt=”” width=”75″ height=”75″ />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.
<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/knights_corner_chip.jpg” alt=”” width=”83″ height=”63″ />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.

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.

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?
<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/beowulf_student_cluster.png” alt=”” width=”99″ height=”79″ />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.
<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/Hans_Meuer.jpg” alt=”” width=”85″ height=”85″ />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.
<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/Guus_Dekkers_small.jpg” alt=”” width=”107″ height=”89″ />Designing an aircraft is one of the more expensive endeavors in the manufacturing business. It’s no surprise that large manufacturers like Boeing and Airbus have turned to computing, and especially high performance computing, to streamline the effort. To get a sense of the current state of the art, we asked Guus Dekkers, CIO of EADS and Airbus, to shed some light on the computational challenges involved.
