Accelerating Eigenpair Computations
Solvers for Edge Plasma Simulation
High Performance Geometric Multigrid
Develop efficient linear and eigensolver algorithms and fast, scalable, library implementations. Integrate the new algorithms and software into DOE applications.
Current expertise in SSG includes:
- dense linear algebra
- factorization-based sparse linear solvers
- multigrid methods
- sparse eigensolvers
- communication-avoiding algorithms -- see, e.g., http://bebop.cs.berkeley.edu/
- mathematical software and libraries
