CCTTSS Research and Development Agenda

The mission of the Center is to develop tools and techniques for component-based software development for high-performance scientific simulations. To support this mission, the Center's research and development agenda is divided into four thrust areas, each coordinated by one of the Center's Principal Investigators. Further details can be found in the Center's SciDAC proposal.

Thrust Area	Activities	Coordinator	Institutions
Overall Center Leadership		Rob Armstrong, SNL	all
Component Frameworks	Integration of prototype frameworks (parallel, distributed, multi-threaded) Language interoperability Component deployment Graphical application builder	Gary Kumfert, LLNL	ANL, IU, LANL, LLNL, SNL, UU
Scientific Components	Development of abstract interfaces and component implementations Scientific data objects: distributed arrays, structured and unstructured meshes, etc. Linear, nonlinear, and optimization solvers Steering and visualization Multi-threading and load redistribution Fault tolerance "Quality of service" research	Lois McInnes, ANL	ANL, IU, ORNL, PNNL, SNL, UU
Parallel Component Coupling	Parallel "MxN" data redistribution Component-based solutions Framework-based solutions Parallel remote method invocation Data decomposition description Model coupling Parallel data exchange Data transformations	Jim Kohl, ORNL	LLNL, LANL, ORNL, UU
User Outreach	General education and outreach activities for component-based software development and the Common Component Architecture Collaboration with adopting projects (tool developers and scientific applications) "In-house" component-based software development/integration research with computational chemistry and global climate modeling application domains as primary foci	David Bernholdt, ORNL	ANL, ORNL, PNNL, SNL and others
