We discuss the design decisions, design alternatives, and rationale behind the third
generation of Peano, a framework for dynamically adaptive Cartesian meshes derived from …

We present sam (oa) 2, a software package for a dynamically adaptive, parallel solution of
2D partial differential equations on triangular grids created via newest vertex bisection. An …

We investigate in this paper the behaviors of the Riemann solvers (Roe and Harten-Lax-van
Leer-Contact (HLLC) schemes) and the Riemann-solver-free method (central-upwind …

Numerical methods based on solving the Riemann problem of the decay of an arbitrary
discontinuity are extremely demanding of computational resources. Applying the data of …

We discuss vectorization of normal and transverse Riemann solvers for the single-and multi-
layer shallow water equations. Our approach is simple and portable, as it is based on auto …

We describe code optimization and parallelization procedures applied to the sequential
overland flow solver FullSWOF2D. Major difficulties when simulating overland flows …

Programmability is one of the key challenges of Exascale Computing. Using the actor model
for distributed computations may be one solution. The actor model separates computation …

We present an efficient Finite Volume solver for the shallow water equations using an actor
extension of the X10 programming language, ActorX10, as programming model. Each actor …

Widespread application of supercomputer technologies in various spheres of life, as well as
the need of high-performance calculations allows us to speak about the relevance of the …

The thesis investigates parallel adaptive structured triangular grids that are generated
corresponding to the Sierpinski space-filling curve. Stack-and stream-based data structures …
