Towards Optimal Petascale Simulations

Towards Optimal Petascale Simulations” (TOPS) is a project funded by
the SciDAC Program at the US Department of Energy (DOE). The project,
which focuses on solver technology, involves partly research and partly
software development. The solvers under consideration include those for
linear and nonlinear equations, eigenvalue calculations, and
PDE-constrained optimization. The project is also concerned with the
deployment of the solver technology in many thrust areas of DOE, such as
accelerator modeling and design, subsurface reactive transport, quantum
chromodynamics, fusion energy research, and materials science. An
important goal of the project is the research and development of
scalable solvers that will allow large-scale scientific simulation codes
to run on forthcoming petascale computer architectures. In this
presentation, the scope of TOPS and some of its on-going work will be
discussed.
