BERKELEY, CA — Scientists at the U.S. Department
of Energy’s Lawrence Berkeley National Laboratory will help lead the development
of a new generation of tools and technologies for scientific computing
under a new $57 million program announced August 14 by the DOE. Under
the program, called Scientific Discovery through Advanced Computing (SciDAC),
Berkeley Lab scientists will lead six of the projects and are key partners
in another six projects.
Berkeley Lab has received approximately $1.9 million for the remainder
of fiscal year 2001 under SciDAC and expects to received more than $6
million annually for the next three to five years, as long as the program
continues.
SciDAC is an integrated program that will help create a new generation
of scientific simulation codes. The codes will take full advantage of
the extraordinary computing capabilities of terascale computers (computers
capable of doing trillions of calculations per second) to address ever
larger, more complex problems. The program also includes research on improved
mathematical and computing systems software that will allow these codes
to use modern parallel computers effectively and efficiently. Additionally,
the program will develop "collaboratory" software to enable
geographically separated scientists to effectively work together as a
team, to control scientific instruments remotely and to share data more
readily.
In all, 51 projects were funded nationwide, involving collaborations
among 13 DOE national laboratories and more than 50 colleges and universities.
More than 150 proposals had been submitted for funding under SciDAC.
"Berkeley Lab’s success in this very competitive SciDAC process
demonstrates the extensive experience and expertise of our staff, and
their ability to determine the best approaches for solving some of the
most challenging problems in computational and computer science,"
said Laboratory Director Charles Shank.
"Berkeley Lab is home to the world’s most powerful unclassified
supercomputer as well as some of the world’s most advanced scientific
research facilities," Shank continued. "Under the SciDAC program,
we will be developing the next generation of scientific simulation codes
to help scientists across the country take even greater advantage of these
resources as they study some of the biggest scientific questions ever
-- What will be the energy source of the future? Is our climate changing?
What are the secrets of our genetic makeup? What is our universe made
of?"
Horst Simon, director of Berkeley Lab’s National Energy Research Scientific
Computing Division, added, "We’re gratified that our lab’s leading-edge
expertise in such areas as Grid technologies, applied mathematics, benchmarking
computer performance and scientific data management have been recognized
and that our staff members are in the vanguard of creating the scientific
computing environment of the future. "With these research projects
now under way, the Department of Energy is poised to redefine how scientific
research is conducted -- and the results will be real breakthroughs in
solving some of the most important scientific problems of our time."
Here are the SciDAC programs Berkeley Lab scientists will be leading:
- Algorithmic and Software Framework for Applied Partial Differential
Equations: The goal is to develop a high-performance framework for solving
partial differential equations arising from problems in magnetic fusion,
accelerator design and combustion -- key mission areas for the DOE.
- Scientific Data Management Integrated Software Infrastructure Center:
Terascale computing (performing trillions of calculations per second)
and large scientific experiments produce enormous quantities of data
that require effective and efficient management, a task that can distract
scientists from focusing on their core research. The goal of this project
is to provide a coordinated framework for the unification, development,
deployment, and reuse of scientific data management software.
- High-End Computer System Performance: This project will focus on how
specific scientific applications can best be run on high-performance
computers. The results of this research are expected to permit the generation
of realistic performance levels, and to determine how applications can
be written to perform at the highest levels and how this information
can be applied to the design of future applications and computer systems.
- Advanced Computing for 21st Century Accelerator Science
and Technology: This project will establish a comprehensive terascale
simulation environment for use by the U.S. particle accelerator community.
This simulation environment will enable accelerator physicists and engineers
across the country to work together to solve the most challenging problems
in accelerator design, analysis, and optimization, advancing the frontiers
of accelerator science and technology.
- DOE Science Grid: This is a multi-laboratory collaborative project
to develop, evaluate and deploy the needed services to support the DOE
Science Grid. A Grid refers to an infrastructure that enables the integrated,
collaborative use of high-end computers, networks, databases, and scientific
instruments owned and managed by multiple organizations. Grid applications
often involve large amounts of data and/or computing and often require
secure resource sharing across organizational boundaries, and are thus
not easily handled by today’s Internet and Web infrastructures. Such
an infrastructure is expected to revolutionize collaborative research
by teams of science around the nation.
- Advanced Methods for Electronic Structure: This project is one of
several in the area of chemical sciences and will focus on the calculation
of the physical and electronic structure of molecules with greater accuracy.
Berkeley Lab scientists will also be collaborating with other national
laboratories and universities on the following SciDAC projects:
- Terascale Optimal Partial Differential Equations Simulations Center:
Large-scale simulations of importance to the DOE often involve the solution
of partial differential equations (PDEs). In such simulations, continuous
(infinite-dimensional) mathematical models are approximated with finite-dimensional
models. To obtain the required accuracy and resolve the multiple scales
of the underlying physics, the finite-dimensional models must often
be extremely large, thus requiring terascale computers. This project
focuses on developing, implementing, and supporting optimal or near
optimal schemes for PDE simulations and closely related tasks. (Lead
institution: Old Dominion University)
- Collaborative Design and Development of the Community Climate System
Model for Terascale Computers: A multi-institutional team will develop,
validate, document and optimize the performance of this coupled climate
model using the latest software engineering approaches, computational
technology and scientific knowledge. (Lead institution: Los Alamos National
Laboratory)
- Scalable Systems Software Integrated Software Infrastructure Center:
This project will address the lack of software for effective management
and utilization of terascale computing resources. This project will
create a virtual center of experts working together to develop an integrated
suite of machine-independent, scalable systems software needed for the
SciDAC program. The goal is to provide open-source solutions that work
on systems ranging in size from small to large. (Lead institution: Oak
Ridge National Laboratory)
- National Collaboratory to Advance the Science of High Temperature
Plasma Physics for Magnetic Fusion Energy: This project will advance
scientific understanding and innovation in magnetic fusion research
by enabling more efficient use of existing experimental facilities and
more effective integration of experiment, theory, and modeling throughout
the national magnetic fusion research community, comprised of over 1,000
researchers from over 40 institutions. The National Fusion Collaboratory
will enable networked real-time data analysis and instantaneous communication
among geographically dispersed teams of experimentalists and theoreticians.
(Lead institution: General Atomics)
- Earth Systems Grid II -- Turning Climate Databases into Community
Resources: High-resolution, long-duration simulations performed with
advanced DOE climate models will produce tens of petabytes of output.
To be useful, this output must be made available to global change impacts
researchers nationwide, both at national laboratories and at universities,
other research laboratories, and other institutions. This project will
create a virtual collaborative environment that links distributed centers,
users, models, and data, significantly increasing the scientific productivity
of U.S. climate researchers by turning climate datasets into community
resources. (Lead institution: Argonne National Laboratory)
- Particle Physics Data Grid Collaborative Pilot: This pilot project
will develop, acquire and deliver vitally needed Grid-enabled tools
for data-intensive requirements of particle and nuclear physics. Novel
mechanisms and policies will be vertically integrated with Grid middleware
and experiment-specific applications and computing resources to form
effective end-to-end capabilities. (Lead institutions: University of
Wisconsin, California Institute of Technology, and Stanford Linear Accelerator
Center)
Concurrently with the announcement of the SciDAC grants, DOE also announced
