In this review we describe a transient type of gas discharge which is commonly called a
streamer discharge, as well as a few related phenomena in pulsed discharges. Streamers …

Block-structured adaptive mesh refinement (AMR) provides the basis for the temporal and
spatial discretization strategy for a number of Exascale Computing Project applications in …

Programming current supercomputers efficiently is a challenging task. Multiple levels of
parallelism on the core, on the compute node, and between nodes need to be exploited to …

We introduce a new relativistic astrophysics code, SpECTRE, that combines a discontinuous
Galerkin method with a task-based parallelism model. SpECTRE's goal is to achieve more …

The cost of data movement has always been an important concern in high performance
computing (HPC) systems. It has now become the dominant factor in terms of both energy …

This paper develops a tree-topological local mesh refinement (TLMR) method on Cartesian
grids for the simulation of bio-inspired flow with multiple moving objects. The TLMR nests …

Turbulence is ubiquitous in the universe and in fluid dynamics. It influences a wide range of
high energy density systems, from inertial confinement fusion to astrophysical-object …

In this paper we discuss a new and very efficient implementation of high order accurate
arbitrary high order schemes using derivatives discontinuous Galerkin (ADER-DG) finite …

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

In this paper we introduce a block-structured adaptive mesh refinement software framework
that incorporates tiling, a well-known loop transformation. Because the multiscale …
