Concrete flow researchers to use Argonne supercomputer
January 24, 2008The Argonne National Laboratory of the Department of Energy (DoE) announced on Jan. 17, 2008, that a team of researchers at the National Institute of Standards and Technology (NIST) has been awarded 750,000 central processing unit (CPU) hours on the IBM Blue Gene/P supercomputer at the Argonne Leadership Computing Facility. The allocation is one of 55 awards of supercomputer time given in a peer-reviewed competition known as the Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program.
The NIST team of William George, Judith Terrill, Nicos Martys, John Hagedorn and Edward Garboczi will use the granted time to study the flow, dispersion and merging of densely suspended, diversely sized and shaped materials (primarily cement in concrete) under a variety of conditions. Access to the Argonne machine will allow computer modeling at a level and range impossible with existing facilities at NIST. The ability to better model real conditions will significantly improve the scientific basis for prediction and measurement of the flow properties of concrete.

The Supermen: The Story of Seymour Cray and the Technical Wizards Behind the Supercomputer by Charles J. Murray (Author) The SUPERMEN "After a rare speech at the National Center for Atmospheric Research in Boulder, Colorado, in 1976, programmers in the audience had suddenly fallen silent when Cray offered to answer questions. He stood there for several minutes, waiting for their queries, but none came. When he left, the head of NCAR's computing division chided the programmers. 'Why didn't someone raise a hand?' After a tense moment, one programmer replied, 'How do you talk to God?'" —from The SUPERMEN The Story of Seymour Cray and the Technical Wizards behind the Supercomputer "They were building revolutionary, not evolutionary, machines. . . . They were blazing a trail—molding science into a product. . . . The freedom to create was extraordinary." —from The Supermen In 1951,... |
