| SuperLU,
one of the ACTS numerical tools,
is a general-purpose library for
the direct solution of large, sparse,
non-symmetric systems of linear equations
on high performance machines. Serial,
shared memory, and distributed memory
implementations are available. SuperLU
was used in a breakthrough quantum
mechanical computation done on the
NERSC Cray T3E and featured on the
cover of the December 24, 1999 issue
of Science (see page
82) |

The
ACTS (Advanced Computational Testing and Simulation) Toolkit is a
set of computational science tools that were mostly developed at DOE
national laboratories and universities. ACTS is an umbrella project
of the DOE Office of Advanced Scientific Computing Research which
has brought the tools together and is funding developers to provide
tool interoperability. The tools in the ACTS Toolkit provide solutions
for numerical problems, scientific data representations, data manipulation,
visualization, program execution, and distributed computing.
NERSC
provides a centralized source of information about the ACTS
Toolkit on the Web, and other services, including:
- outreach to researchers in new and expanding scientific computing
areas
- educational programs, including workshops and lectures
- evaluation of current tools for interoperability, robustness,
functionality and ease of use
- ongoing support for users in the scientific community.
In
September, NERSC presented a three-day workshop on the ACTS Toolkit
for graduate students and postdoctoral fellows. Toolkit tutorials
were also offered at SC2000 in November.
