美国正在开发下一代超级计算机 比天河一号更快 新浪科技 张和 北京时间2010年11月15日上午消息，美国正在开发两套运算能力达20千万亿次(petaflop)浮点运算能力的超计算机系统。这两套系统性能将远远超过市场上任何现有计算机，包括最近刚刚获得全球最快计算机称号的中国“天河一号”。 这两套新设备由美国橡树岭国家实验室设计建造。该实验室此前曾设计建造过排名世界第一的“美洲虎”超级计算机。 美国国家计算科学中心主任詹姆斯·海克(James Hack)表示，新超级计算机系统将于2012年进入运行阶段。 IBM也在为劳伦斯利弗莫尔国家实验室建造另一套浮点运算能力超过20千万亿次的超级计算机。IBM称该系统将于明年底部署到实验室，2012年实现生产。劳伦斯利弗莫尔实验室发言人表示，新超级计算机预计将参与2012年6月份的Top500超级计算机排名。 James Hack：  National Center for Computational Sciences Director—James J. Hack James J. Hack directs the National Center for Computational Sciences (NCCS), a leadership computing facility at Oak Ridge National Laboratory supporting transformational science. He identifies major high performance computing needs from scientific and hardware perspectives and puts forth strategies to meet those needs as machines evolve to the petascale, able to carry out a quadrillion calculations per second. An atmospheric scientist, Hack also leads ORNL’s Climate Change Initiative. After receiving a Ph.D. in atmospheric dynamics from Colorado State University in 1980, Hack became a research staff member at the IBM Thomas J. Watson Research Center, where he worked on the design and evaluation of high-performance computing architectures. In 1984 he moved to the National Center for Atmospheric Research, a National Science Foundation-sponsored center, where his roles included senior scientist, head of the Climate Modeling Section, and deputy director of the Climate and Global Dynamics Division. He was one of the principal developers of the climate model that ran on NCCS supercomputers to provide more than one-third of the simulation data jointly contributed by the Department of Energy and the National Science Foundation to the most recent assessment report of the United Nations’ Intergovernmental Panel on Climate Change, the group that shared the 2007 Nobel peace Prize with Al Gore. He has also held an adjoint professor position at the University of Colorado at Boulder and is author or co-author of 98 scientific or technical publications. Hack is a member of the DOE’s Advanced Scientific Computing Advisory Committee and the Working Group on Numerical Experimentation, sponsored by the Joint Scientific Committee for the World Climate Research Program and the World Meteorological Organization Committee for Atmospheric Sciences. He also chairs the Lawrence Livermore National Laboratory/Program for Climate Model Diagnosis and Intercomparison Advisory Committee. He has served on the ORNL Computer Science and Mathematics Division Advisory Committee, a wide variety of NSF high-performance computing review and advisory panels, the U.S. Water Cycle Scientific Steering Group, and was editor for the Journal of Climate. He was also a founding member of DOE’s Computational Science Graduate Fellowship Program, a highly successful educational initiative in which he continues to participate. http://www.nccs.gov/about/organization/management/ |
