...... (c) From on 2008.12.13: "Genetic Data Transfer Time Between TGen-ASU To Be Slashed By Light-speed Computer Connection" More... "Because of the huge amounts of data generated by TGen's experiments, it now take as long as 12 days using conventional cables to transmit 7 terabytes of information from a typical experiment 10 miles between TGen's downtown Phoenix labs and ASU's new Saguaro 2 supercomputer in Tempe."

From Cray To NVIDIA To OpenCV
2010.09.21: "Cray to Add NVIDIA GPUs to the Cray XE6 Supercomputer"
   "Our customers have expressed a growing interest in having 
    accelerator technology in Cray systems, and we believe a 
    Cray XE6 blade with NVIDIA GPUs will provide the performance, 
    scalability, and reliability that a growing segment of our 
    customer base is looking for." -- Barry Bolding, a Cray VP
2010.09.23: "NVIDIA Adds GPU Acceleration for OpenCV Application Development"
   "Computational power in Computer Vision has been a limiting factor 
   not only for the use of recent powerful algorithms in object 
   recognition, tracking and 3D reconstruction, but also has limited 
   the creativity of algorithms people are willing to invent," said 
   Gary Bradski, senior researcher at Willow Garage, and founder of 
   OpenCV. "With CUDA GPU acceleration, many OpenCV algorithms will 
   run five to ten times faster, making current algorithms more 
   practical for application developers and allowing the invention 
   and combination of more capable applications in the future."


   "My research lab uses OpenCV extensively in our autonomous vehicles."

      engineering at Stanford University Thrun's Homepage Bradski - Senior Researcher Wiki

Supercomputing: There's an App for That
The TACC (Texas Advanced Computing Center) is a computing center that is probably going to end up doing great things.
   "What if you could perform supercomputing calculations 
    in real-time, on your smartphone, in any location?"

   "Researchers at the Massachusetts Institute of Technology 
    (MIT), collaborating with staff at the Texas Advanced 
    Computing Center (TACC), have created an application 
    that does just that." There's an App for That

NOAA and the ORNL Collaborate on CMRS
CMRS stands for Climate Modeling and Research System.
   "In Year 1, the new CMRS provides a 5x increase in computational 
    capability over NOAA's current largest system. In the second year, 
    the capacity quadruples to more than 1.1 petaflops. This is a 
    huge resource, delivered in step with the scientific community's 
    needs." Climate Research Collaboration Sets Lofty Goals for New Supercomputer

    processing power and yet have almost none of the features 
    of the computers we build today. Don't you find this odd?" future of computing? The SpiNNaker million processor computer

OHPC is "Omnipresent High Performance Computing" and DARPA wants it as part of its UHPC (Ubiquitous High Performance Computing) program. the petaflop: DARPA wants quintillion-speed computers

[23 June 2010, top] On Exascale Computing Challenges
The following was copied from National Economic Council's "A Strategy for American Innovation: Driving Towards Sustainable Growth and Quality Jobs" found on the website.
   "An 'exascale' supercomputer capable of a million trillion calculations 
    per second - dramatically increasing our ability to understand the 
    world around us through simulation and slashing the time needed to 
    design complex products such as therapeutics, advanced materials, 
    and highly-efficient autos and aircraft." - Challenges to exascale computing (by Irving Wladawsky-Berger)

The DoD Likes Cray Supercomputers
Cray Inc. announced it had "won three high-performance computing awards from the U.S. Department of Defense that total more than $45 million."
   "Cray said its supercomputers will be used to support basic and 
    applied research, and product development and evaluation. These 
    systems will help to protect the military through the development 
    of new materials, fuels, armor and weapons systems, and assist 
    long-term weather predictions to plan humanitarian and military 
    operations throughout the world."

Upon receiving this contract, Cray will have "supercomputing systems at five of the six DoD Supercomputing Resource Centers in the U.S."

On 23 February 2010, prior to the announcement, CRAY shares closed at $5.17 per share.

Smokey Bear Needs HPC
I remain a sucker for catchy headlines and the headline "Smokey Bear Now Studies Computer Science" attracted my attention.

In a nutshell, computing is being used to better "understand wildfire behavior and predicting its spread."

   "Even on supercomputers, you're really limited," Cunningham said. 
   "To have your smallest scale at 1 meter and your biggest scale at 
    let's say 10, or 100, kilometers you just can't do it based on 
    the computational power available." -- Phil Cunnigham is a 
    "former Florida State University associate professor of 
     meteorology who has just moved to LANL (Los Alamos National
     Laboratory [home the Roadrunner supercomputer]). Bear Now Studies Computer Science

Cray Adds New Customers
Cray issued a press release announcing they had a couple of new customers.

Tokyo, Japan-based Institute of Statistical Mathematics will use supercomputing to "perform statistical data analysis, statistical modeling, mathematical analysis and statistical interference."

In Germany, the University of Duisburg-Essen will use supercomputing to "support its scientific work in chemistry, physics, mathematics and engineering. Research will include the development of parallel algorithms, large-scale computations of electronic structure and molecular dynamics of nano materials, as well as structural mechanics and biomechanics studies."

   "The simulations that will be performed on our new Cray 
    supercomputer will contribute significantly to the atomistic 
    understanding of structure and reactivity in the nano sciences, 
    energy technology and material sciences, as well as to insight 
    into structural and biomechanical problems." 
    -- Prof. Dr. Eckhart Spohr at University of Duisburg-Essen 

I liked encountering the word atomistic.

Supercomputer-Based Healthcare Reform?
I'm of the opinion that Andrew Loebl is correct.
   "Combining and analyzing health care data in real time could 
    save as much as $50 billion a year by eliminating waste and 
    preventing fraud in government-run health care programs, and 
    also could improve the quality of medical care, said Andrew 
    Loebl, a senior researcher in the lab's Computational Science 
    and Engineering Division."

Right now the roadmap is for exa-scale computing by 2018. Could it happen sooner? I thank maybe. the world's fastest supercomputer combat health care waste?

#in2020 Exaflops Computing
I (@mathbabbler) tweeted the following on 2009.01.02.
   #in2020 Exaflops computing (i.e. 1,000,000,000,000,000,000 
   arithmetic calculations per second).

A few months ago the interval 2018-2020 was used as a prediction as to when we would have exa-scale computing; however, now 2018 seems to be the target year.
