ASC Business Model
Terascale Simulation Facility
Instiitute for Terascale Simulation - Established in
October 1999 and housed within CASC, the ASC
Institute for Terascale Simulation (ITS) sponsors in-house research and collaborative
research with academia in areas of computer science, computational mathematics,
and scientific computing relevant to the Stockpile Stewardship Program. It brings
leading academicians and their students to LLNL on sabbaticals, summer visits,
and short-term visits, to work with Laboratory researchers on the challenging
problems of ASC. The ITS currently concentrates on scalable numerical algorithms,
parallel programming paradigms, and scientific data explorationall with
an emphasis on scalability to tens of thousands of processors.
Center for Applied Scientific Computing - The Center
for Applied Scientific Computing (CASC) conducts collaborative scientific
investigations that utilize the power of high-performance computers and the efficiency
of modern computational methods. Research and development activities are applications-driven
and focus on Department of Energy programmatic objectives that require advanced
computational technologies. Core competencies include high-performance computing,
numerical mathematics, computational physics, algorithm development, and scientific
data management and visualization.
Institute for Scientific Computing Research - The mission
of the Institute for Scientific Computing
Research (ISCR) is to foster collaborations between LLNL and academic researchers
in the areas of scientific computing, computer science, and computational mathematics.
The ISCR is jointly administered by the LLNL's University Relations Program (URP)
and CASC, and this joint relationship also expresses its mission.
The ISCR is the administrative host and technical matchmaker for several dozen
summer or year-round graduate students, post-doctoral fellows, and visiting faculty.
The ISCR also has substantial collaborations with UC researchers that take place
on UC campuses as well as in residence at the Lab. Many of these research collaborations
are centered on the Laboratory's unique computational facilities, which include
the world's most powerful general-purpose scientific supercomputer.
The ISCR also administers the university portion of the ASC ITS, which sponsors
technical workshops and short courses, a distinguished lecturer series, and summer
tutorials for graduate students. An extensive externally networked ISCR cost-effectively
expands the level and scope of national computational science expertise available
to the Laboratory, while disseminating the Laboratory's own contributions to
the national community.
