A Modest Proposal for Petascale Computing

February 8, 2008

In an editorial in the February 8 issue of HPCwire titled “A Modest Proposal for Petascale Computing,” editor Michael Feldman writes:

In typical forward-thinking California fashion, the folks at Lawrence Berkeley National Laboratory (LBNL) are already looking beyond single petaflop systems, even before a single one has been released into the wild. LBNL researchers have started to explore what a multi-petaflop computer architecture might look like. Even ignoring the challenge of software concurrency, they point out that power and system costs will determine how such machines can be built....

At last year's SIAM Conference on Computational Science and Engineering, LBNL researchers Lenny Oliker, John Shalf, [and] Michael Wehner authored a presentation about what kind of supercomputer would be required for a climate modeling system with kilometer-scale fidelity.

Feldman describes this research as a “paradigm shift [in] thinking about supercomputers as appliances rather than as general-purpose computers.” The complete HPCwire article can be read here.

About Computing Sciences at Berkeley Lab

The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.

ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 7,000-plus scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are Department of Energy Office of Science User Facilities.

Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
