Why the U.S. Must Lead in Supercomputing

“China officially claimed the world’s second-fastest computer earlier this month. China was in fifth place just six months ago — and is expected to have the world’s fastest machine by year end. While its systems currently rely on U.S. components, China is already constructing comparable machines using its domestic technology. These challenges to U.S. leadership in supercomputing and chip design threaten our country’s economic future.”

So begins an opinion piece by DOE Undersecretary for Science Steven E. Koonin in this morning’s San Francisco Chronicle. Read more.

CS Announces New Safety Competition

Berkeley Lab Computing Sciences staff are encouraged to send near-miss safety hazards and safety suggestions to Safety Coordinator Betsy MacGowan. Horst Simon, Betsy MacGowan, and the CS Safety Committee will select the “CS Safety Top 10” suggestions that provide the greatest improvement to Lab safety. Employees who submit the winning entries will be recognized with a Spot Award, which includes a cash prize.

This safety competition is being launched as part of Berkeley Lab’s initiative to transform the safety culture at the Lab. The competition is open to CS staff, guests and matrixed employees, and is intended to increase awareness of safety issues within CS, CRD, and NERSC. The “CS Safety Top 10” winners will be featured on the Computing Sciences website. All safety submissions for the first cycle are due on August 31, and the winners will be announced in September. Deadlines, winners, and the Top 10 list will be announced periodically in InTheLoop.

This Week’s Computing Sciences Seminars

A Forward Looking Evolutionary View of Computing for a Large Physics Experiment (STAR)
Monday, June 14, 9:30–10:30 am, 50F-1647
Jerome Lauret, Brookhaven National Laboratory, Leader, STAR Software and Computing Project

As Moore’s Law has driven exponential growth in compute and storage, it has also driven growth in the capabilities and data generation of experimental physics. Three orders of magnitude increase in storage and compute resource needs for the STAR experiment since its inception (the 10th year of data taking is just completed) are driving a transition from localizing resources in a dedicated facility to utilizing shared, opportunistic and even commercial cloud resources. STAR has been a participant in the development of grid computing in the Particle Physics Data Grid and Open Science Grid and is currently active in the utilization of cloud resources accessed through grid infrastructure. The Cloud paradigm is an important and necessary evolution of a distributed computing model beyond the foundation technologies provided by grid services. The driving forces in the computational aspects of experimental physics will continue to demand evolution of the software and computing capabilities of STAR. We are currently on the threshold of the transition from serial computing (embarrassingly parallel) to efficient use of multi-core processors. With these and other trends, the next 5+ years promises to be dynamic, challenging and exciting for STAR and experimental physics in general.

High Performance Flow Simulations on Graphics Processing Units
Thursday, June 17, 12:00–1:00 pm, 90-3122
Wangda Zuo, LBNL Energy and Environmental Technologies Division

Building design and operation often requires real-time or faster-than-real-time simulations for detailed information on air distributions. However, none of the current flow simulation techniques can satisfy this requirement. To solve this problem, a Fast Fluid Dynamics (FFD) model has been developed. The FFD can solve Navier-Stokes equations at a speed of 50 times faster than Computational Fluid Dynamics (CFD). In addition, the computing speed of the FFD program has been further enhanced up to 30 times by executing in parallel on a Graphics Processing Unit (GPU) instead of a Central Processing Unit (CPU). As a whole, the FFD on a GPU can be 1500 times faster than the CFD on a CPU.

Consortium for Electric Reliability Technology Solutions Organization and Research Overview
Thursday, June 17, 2:00–3:30 pm, 50B-4205
Joseph Eto, LBNL Energy and Environmental Technologies Division

The U.S. electric power system is in the midst of a fundamental transition from a centrally planned and utility-controlled structure to one that will depend on competitive market forces for investment, operations, and reliability management. Electricity system operators are being challenged to maintain the reliability of the grid and support economic transfers of power as the industry’s structure changes and market rules evolve. Meanwhile, the U.S. economy depends more than ever on reliable and high-quality electricity supplies. New technologies are needed to prevent major outages such as those experienced on August 14, 2003, which cost an estimated $4–10 billion and affected tens of millions of customers.

The Consortium for Electric Reliability Technology Solutions (CERTS) was formed in 1999 to research, develop, and disseminate new methods, tools, and technologies to protect and enhance the reliability of the U.S. electric power system and efficiency of competitive electricity market. CERTS’ vision is to:

  • Transform the electricity grid into an intelligent network that can sense and respond automatically to changing flows of power and emerging problems;
  • Enhance reliability management through market mechanisms, including transparency of real-time information on the status of the grid;
  • Empower customers to manage their energy use and reliability needs in response to real-time market price signals; and
  • Seamlessly integrate distributed technologies—including those for generation, storage, controls, and communications—to support the reliability needs of both the grid and individual customers.

The founding members of CERTS are LBNL, ORNL, PNNL, SNL, NSF’s Power System Engineering Research Center, and the Electric Power Group. LBNL serves as the program office for CERTS (http://certs.lbl.gov/).

Link of the Week: Ranking and Mapping Scientific Knowledge

Science is a massively parallel human endeavor to explain and predict the nature of the physical world. In science, knowledge is acquired cumulatively and collaboratively—and the principal mode for sharing this knowledge is the institution of scholarly publishing. In science, ideas are built upon ideas, models upon models, verifications upon prior verifications. This cumulative process of construction leaves behind it a latticework of citations, from which we can reconstruct the geography of scientific thought and retrace the paths along which intellectual activity has proceeded.

The Eigenfactor Project is a non-commercial academic research project sponsored by the Bergstrom lab in the Department of Biology at the University of Washington. They aim to use recent advances in network analysis and information theory to develop novel methods for evaluating the influence of scholarly periodicals and for mapping the structure of academic research. Results include maps of how different fields of science influence each other, and samples of four different ways of visualizing information flow in science. You can check out the rankings of individual journals from their home page.
