Wilkie: SC12 was all about the Science

Over at Scientific Computing World, Tom Wilkie writes that SC12 was all about science.

Nervousness about the commitment of the US Government and the Congress to this sort of long-term investment in technology could be seen at the official SC12 press conference, where Dona Crawford, associate director, Computation, at the Lawrence Livermore National Laboratory, announced that the US Council on Competitiveness is to be funded to the tune of nearly one million dollars over the next three years to develop recommendations to Congress on extreme computing. Why should this be necessary, journalists at the press conference asked, when the Department of Energy had already sent to Congress, in February, its plan to build an exascale machine before the end of the decade.

Will China Win the Race to Exascale?

Over at Computerworld, Patrick Thibidous writes that China has impressed analysts with its rocket-speed commitment to HPC. And with budget cuts threatening to stall next-generation supercomputer development in the U.S., one has to wonder if the Chinese beat us to Exascale with home-grown technologies.

For its Tianhe-1A system, China turned to U.S. chips — Intel’s Xeon processors — but used a China-developed interconnect. With its Sunway BlueLight supercomputer, China used its own chip, the Shen Wie SW 1600 microprocessor, but with InfiniBand interconnects. “You can see what they’re doing,” said Beckman, explaining that China’s developers reduce risk by mixing and matching standard technologies with homegrown approaches. “Now, you can see what’s going to happen,” said Beckman. “You take your homegrown CPU, the homegrown network, and you put them together and you have a machine that from soup to nuts is a technical achievement for China and is really competitive.”

DDN Announces $100 Million Investment In Exascale Computing

This week at SC12, DDN announced a $100 million investment in its research and development efforts, specifically directed at resolving key challenges to achieving Exascale levels of performance in scientific computing. The new investments by DDN represent a substantial percentage of DDN’s engineering resources and will be directed toward technology challenges, which become critical at Exascale proportions, including: I/O Acceleration; Converged Infrastructure; Information Value Extraction; and Energy and Data Center Efficiency.

Data-intensive computing impacts individuals, organizations, industries and governments by enabling the creation of valuable information based on massive volumes of highly complex data,” said Alex Bouzari, CEO and cofounder, DDN. “Significant investment is required to allow researchers to address challenges such as the design of new materials needed for better electric car batteries, the improvement of multi-physics models for more accurate severe weather modeling, and the development of high-resolution cosmological simulations to help understand dark matter and the universe around us. With today’s announcement, DDN is establishing a clear direction for our Exascale computing agenda and reaffirms DDN’s continued central role in the future of supercomputing.”

DDN disclosed that the investments will center around the following critical technologies for Exascale computing:

  • I/O Acceleration: New file system, middleware and storage tiering methods will be required to eliminate scalability barriers associated with conventional methods of file, object and database access in order to achieve 1,000x scalability, TB/s performance and million-way application CPU parallelism.
  • Converged Infrastructure: The convergence of computing, storage and networking technologies will give rise to intelligent and accelerated data storage infrastructures which can co-locate pre-processing and post-processing routines natively within the storage infrastructure to enable applications to access data with increased acuity.
  • Information Value Extraction: Leveraging converged infrastructures, DDN R&D efforts will support the development of scalable data analytics environments to extract actionable insights from vast volumes of unstructured data.
  • Energy and Data Center Efficiency: With the emergence of storage-class memory and software tools, infrastructures can be built with fewer components compared to today’s disk-based technologies. These initiatives will serve to significantly reduce hardware acquisition costs but will also make data centers much more space and power efficient by reducing storage footprint by more than 75%.

This is exciting news for the HPC community looking to see more vendors step up to the plate for the incredibly daunting goal of Exascale computing within this decade. I can tell you that the DDN booth was packed with people all week at SC12. Read the Full Story.

TotalView’s Massive Milestone Towards Exascale Debugging

At the SC12 conference, Rogue Wave Software, announced that TotalView has achieved a significant debugging milestone during testing conducted as part of its strategic scalability initiative, demonstrating its capability to debug a parallel job running on 786,432 processor cores. The tests were conducted on Lawrence Livermore National Laboratory’s (LLNL) Sequoia, its IBM Blue Gene/Q supercomputer .

We are actively working to increase the capabilities of our scientific codes to scale and take advantage of the phenomenal power of Sequoia,” stated Scott Futral, LLNL group leader for Development Environment. “As part of this effort, we are looking for ways to get more on-node parallelism from existing codes and architecting our new codes to support the even more massive degrees of parallelism that we know will be needed in the future. Rogue Wave’s dedication to pushing for ever-increasing scales with its TotalView debugger and the recent tests give us reason to be confident that TotalView will continue to be a critical development tool as we reach higher and higher scales with our own codes.”

Rogue Wave will announce the result of this second set of tests, which demonstrate successful debugging of an even higher number of threads, on Thursday November 15th at 12:00 PM MST. Visit SC12 Rogue Wave booth #3418, to participate in a competition to correctly guess the number of threads TotalView debugged. Read the Full Story.

Interview: AMD’s John Gustafson on the Challenges of Exascale

Over at The Exascale Report, Mike Bernhardt has posted an interesting interview with John Gustafson, newly appointed Senior Fellow and Chief Product Architect for AMD’s Graphics Business Unit.

If you can solve the performance-per-watt problem, then the next challenges are building a good software model, followed by resilience and reliability, all areas where AMD will undoubtedly make key contributions. I’m questioning that we should just be pumping out ten to the eighteenth double precision operations all the time as our goal, because in most areas of computing, there is a way to improve the quality of the computation and the validity of the results, and we need to be taking a much harder look at ‘what the heck are we computing anyway?’ and not just blindly apply finer meshes and more time steps. It’s time to think about the physics really hard and ask what is the problem we are trying to solve.”

Exascale Report: What’s at stake for HPC in the U.S. Presidential Election?

Over at The Exascale Report, Mike Bernhardt writes that supercomputing has a lot at stake with the 2012 U.S. Presidential election.

Politicians on both sides of the fence say they support HPC, but it appears to be nothing more than lip service. We are just not seeing the commitment to the kind of long term strategy needed to drive exascale – or for that matter, even advanced HPC research. We are all at the mercy of what the hardware vendors can build – what they believe will drive product sales in the near term. HPC innovation and exascale development require strong, unified Federal funding, and this goes hand in hand with economic recovery. And, without adequate funding and a strong commitment to technology leadership, I fear the U.S. may not even finish in this world-changing race.”
