SCIENTIFIC DISCOVERYVACET, ESG partner for new Climate toolsVACET, a SciDAC visualization project, is working to help bring advanced visualization technology to the climate modeling and analysis community through a partnership with the Earth Systems Grid (ESG). During the past several months, VACET has been working closely with ESG to prepare both new tools/technologies and material for presentation at the December 2009 climate meeting in Copenhagen. Prior to working with VACET, ESG's viz/analysis tool (Climate Data Analysis Toolkit, CDAT) consisted of only 1D & 2D charting/plotting tools. VACET’s role has been to roll out new 3D/4D visualization technologies that are now included in the CDAT release. This effort is beginning to bear fruit, with the first set of objectives: 3d slicing, isocontouring, multiple linked 3D views, and 3D moviemaking. This image, one frame from the complete video which was shown in the WCRP booth at the climate meeting in Copenhagen, demonstrates the use of the visualization to communicate an important insight. The insight in this example is that the outer layer of the atmosphere is cooling while the lower layer is warming. The other activity conducted in the process of developing this video was demonstrating that this visualization could be realized in real time while transferring massive amounts of data. The real time visualization demonstration was a finalist in the Supercomputing 2009, Bandwidth Challenge, (November 2009). The team was recognized for demonstrating the transfer of 10TB of climate data and producing this visualization in real time on the receiving end. link to highres QT movie (~48MB)

ACM (Association for Computing Machinery) Fellows are recognized for their contributions to computing and computer science that have contributed fundamental knowledge to the field and generated a broad range of innovations in industry, commerce, entertainment, and education.
DOE labs sweep major awards at SC09 conferenceORNL-Led Team Takes Gordon Bell Prize for World’s Fastest Science AppA team led by ORNL’s Markus Eisenbach was named winner of the 2009 ACM Gordon Bell Prize, which honors the world’s highest-performing scientific computing applications. Another team led by ORNL’s Edo Aprà was also among nine finalists for the prize. Results of the contest were announced in Portland, Oregon, during the SC09 international supercomputing conference. The prize is supported by high-performance computing pioneer Gordon Bell and is administered by the Association for Computing Machinery. IBM-LBNL Simulation of Cat-Size Cortex is a Gordon Bell Prize Special Category WinnerA team of researchers from the IBM Almaden Research Center and the Lawrence Berkeley National Laboratory won the prestigious Gordon Bell Prize in the special category for their development of innovative techniques that produce new levels of performance on a real application. This year's prize winners were announced Thursday, Nov. 19, 2009 at the awards session of the SC09 conference in Portland. The ACM Gordon Bell Prize annually recognizes the best performance of scientific applications on supercomputers. more Tennessee Supercomputing Titans Triumph at SC09 HPC Challenge AwardsTwo powerful Cray XT5 systems at the ORNL computing complex outmuscled competitors to win half of this year’s High-Performance Computing (HPC) Challenge awards. Results of the “Best Performance” awards, which measure excellence in handling computing workloads, were announced Nov. 17 at SC09. ORNL’s Jaguar took home the lion’s share of the honors, with three gold medals and one bronze. Kraken, an academic supercomputer located at ORNL and funded by the National Science Foundation (NSF) through a partnership with the University of Tennessee, showed that it too is a contender with two silver medals. Jaguar won first place for speed in solving a dense matrix of linear algebra equations by running the HPL software code at 1,533 teraflop/s (trillion floating point operations per second). Kraken, the world’s fastest academic computer, took second by running HPL at 736 teraflop/s. Jaguar also ranked first for sustainable memory bandwidth by running the STREAM code at 398 terabytes per second. STREAM measures how fast a node can fetch and store information. Jaguar’s third gold was for executing the Fast Fourier Transformation (FFT), a common algorithm used in many scientific applications, at 11 teraflop/s. Kraken took second with a speed of 8 teraflop/s. SDSC, UC San Diego, LBNL Team Wins SC09 'Storage Challenge' AwardA research team from the San Diego Supercomputer Center (SDSC) at UC San Diego and the University of California's Lawrence Berkeley National Laboratory (Berkeley Lab) has won the Storage Challenge competition at SC09, the leading international conference on high-performance computing, networking, storage and analysis held Nov. 14-20 in Portland, Oregon. The research team based its Storage Challenge submission for the annual conference on the architecture of SDSC's recently announced Dash high-performance computer system, a "super-sized" version of flash memory-based devices such as laptops, digital cameras and thumb drives that also employs vSMP Foundation software from ScaleMP, Inc. to provide virtual symmetric multiprocessing capabilities. Berkeley Lab's Peter Nugent and Janet Jacobsen provided the project a production database that they could use for the data challenge, and did so in a short time. more |
