Fast and scalable solvers for the Helmholtz equation
… this thesis we develop a new family of fast and scalable algorithms to solve the 2D high-frequency Helmholtz equation in heterogeneous medium. The algorithms rely on a layered domain decomposition and a coupling between subdomains using the Green's representation formula, which reduces the …

Scalable non-blocking Krylov solvers for extreme-scale computing
Krylov solvers are key kernels in many large-scale science and engineering applications for solving sparse linear systems. Extreme-scale systems have many factors that increase communication costs and cause performance variation across cores that can reduce performance at scale. Many Krylov solvers …
