The award was announced at the Supercomputing 2010 conference, Nov. 18 in New Orleans.\u003C\/p\u003E\u003Cp\u003EBiros and his 11 teammates, which included colleagues not only from Georgia Tech but also from Oak Ridge National Laboratory (ORNL) and New York University (NYU), created a blood-flow simulation of 260 million deformable red blood cells flowing in plasma. The team ran its application on ORNL\u2019s Jaguar supercomputer. Using 196,000 of Jaguar\u2019s 224,000 processor cores, the application pushed the machine to 700 trillion calculations per second, or 700 teraflops. The simulation amounted to successful resolution of 90 billion unknown dimensions in space, and topped the previous largest blood-flow simulation (of 14,000 cells) by four orders of magnitude.\u003C\/p\u003E\u003Cp\u003E\u201cWe put this team together to tackle the mathematical and computational challenges associated with blood-flow simulation, and while our research is an important step, it is only a first step, which we hope to expand upon in the coming years,\u201d said Biros, who has a joint appointment in the Wallace H. Coulter Department of Biomedical Engineering. \u201cMoving forward, I hope this award spotlights Georgia Tech\u2019s research and contributions to high-performance computing. We are honored to have received the prize and are truly grateful for the recognition of our work by our colleagues.\u201d\u003C\/p\u003E\u003Cp\u003EThe simulation is described in a paper, \u0022Petascale Direct Numerical Simulation of Blood Flow on 200K Cores and Heterogeneous Architectures,\u201d presented at SC10. Georgia Tech team members included assistant professor Richard Vuduc; research technologist Logan Moon; adjunct scientist Ilya Lashuk; graduate students Abtin Rahimian and Aparna Chandramowlishwaran (both Ph.D. students in CSE), and Aashay Shringarpure (M.S. student in computer science); and former undergraduate intern Dhairya Malhotra. ORNL team members included Future Technologies group leader Jeffrey Vetter (who has a joint appointment in Georgia Tech\u0027s School of CSE) and postdoctoral researcher Rahul Sampath. Professor Dennis Zorin and postdoctoral researcher Shravan Veerapaneni were the NYU team members.\u003C\/p\u003E\u003Cp\u003E\u201cWe are very proud of George and all his teammates from such esteemed partner institutions as Oak Ridge National Lab and NYU,\u201d said Zvi Galil, John P. Imlay Jr. Dean of Computing at Georgia Tech. \u201cSupercomputing is the tool that will enable science to address some of the truly grand challenges of our time, from curing our most pernicious diseases to successfully predicting severe weather. At Georgia Tech we are committed to attracting the best high-performance computing researchers in the country\u2014and giving them the tools they need to do their work.\u201d\u003C\/p\u003E\u003Cp\u003EPart of what made the team\u2019s accomplishment so impressive is that their application simulated not artificially spherical blood cells that retain their shape, but realistic cells that deform as they move through plasma. In announcing the award, Horst Simon, associate laboratory director for computing sciences at Lawrence Berkeley National Laboratory (and a former Bell Prize winner), called the simulation a \u201cvery challenging multiscale, multiphysics problem\u201d and its successful execution \u201ca very significant accomplishment.\u201d\u003C\/p\u003E\u003Cp\u003E\u201cWe would like to thank the National Science Foundation and the \nDepartment of Energy for their support and for providing the \ncomputational resources that made these calculations possible,\u201d Biros said. \u201cOur long-term goal is to investigate the design of diagnostic \nmicrofluidic devices and develop a quantitative understanding of blood \nclotting mechanisms. The main challenge in modeling blood flow is \nresolving the hydrodynamic \ninteractions between erythrocytes with the surrounding plasma.\u201d\u003C\/p\u003E\u003Cp\u003EThe Bell Prize, named for supercomputing pioneer Gordon Bell, has been awarded every year since 1987 in recognition of the world\u2019s fastest supercomputing application. It carries a $10,000 cash prize for the winner.\u003C\/p\u003E\u003Cp\u003E###\u003Cstrong\u003E\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EAbout the Georgia Tech College of Computing\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EThe Georgia Tech College of Computing is a national leader in the creation of real-world computing breakthroughs that drive social and scientific progress.
