In this paper, a new approach to vectorization of algorithms of computational fluid dynamics
to simulate the dynamics of astrophysical objects is presented. A co-design of a …

Smoothed particle hydrodynamics (SPH) schemes need to be enhanced by dissipation
mechanisms to handle shocks. Most SPH formulations rely on artificial viscosity and, while …

This article studies mini‐applications—Minisweep, GenASiS, GPP, and FF—that use
computational methods commonly encountered in HPC. We have ported these applications …

We use OpenMP to target hardware accelerators (GPUs) on Summit, a newly deployed
supercomputer at the Oak Ridge Leadership Computing Facility (OLCF), demonstrating …

We present an initial report on 160 simulations of a highly simplified model of the post-
bounce core-collapse supernova environment in three spatial dimensions (3D). We set …

This paper describes algorithms for nonrelativistic hydrodynamics in the toolkit for high-order
neutrino radiation hydrodynamics (thornado), which is being developed for multiphysics …

A computational hydrodynamic model of interacting galaxies is presented. The interstellar
medium (ISM) is described by a model of gravitational multicomponent single-velocity …

High-bandwidth storage tiers are becoming more common for their capability to absorb high-
rate, bursty I/Os. Notably, the designs of these fast storage tiers differ from system to system …

The large-scale computer simulation of a system of physical fields governed by partial
differential equations requires some means of approximating the mathematical limit of …

We present an overview of a software system, Bellerophon, built to support a production-
level HPC application called CHIMERA, which simulates core-collapse supernova events at …
