Scaling Computational Fluid Dynamics: In Situ Visualization of NekRS using SENSEI
Victor A. Mateevitsi, Mathis Bode, Nicola Ferrier +9
In the realm of Computational Fluid Dynamics (CFD), the demand for memory and computation resources is extreme, necessitating the use of leadership-scale computing platforms for pr…
Distributed Neural Representation for Reactive in situ Visualization
Qi Wu, Joseph A. Insley, Victor A. Mateevitsi +3
Implicit neural representations (INRs) have emerged as a powerful tool for compressing large-scale volume data. This opens up new possibilities for in situ visualization. However,…
Farpoint: A High-Resolution Cosmology Simulation at the Gigaparsec Scale
Nicholas Frontiere, Katrin Heitmann, Esteban Rangel +7
In this paper we introduce the Farpoint simulation, the latest member of the Hardware/Hybrid Accelerated Cosmology Code (HACC) gravity-only simulation family. The domain covers a v…
The Last Journey. I. An Extreme-Scale Simulation on the Mira Supercomputer
Katrin Heitmann, Nicholas Frontiere, Esteban Rangel +10
The Last Journey is a large-volume, gravity-only, cosmological N-body simulation evolving more than 1.24 trillion particles in a periodic box with a side-length of 5.025Gpc. It was…
The Outer Rim Simulation: A Path to Many-Core Supercomputers
Katrin Heitmann, Hal Finkel, Adrian Pope +10
We describe the Outer Rim cosmological simulation, one of the largest high-resolution N-body simulations performed to date, aimed at promoting science to be carried out with large-…
The Q Continuum Simulation: Harnessing the Power of GPU Accelerated Supercomputers
Katrin Heitmann, Nicholas Frontiere, Chris Sewell +6
Modeling large-scale sky survey observations is a key driver for the continuing development of high resolution, large-volume, cosmological simulations. We report the first results…
The Universe at Extreme Scale: Multi-Petaflop Sky Simulation on the BG/Q
Salman Habib, Vitali Morozov, Hal Finkel +9
Remarkable observational advances have established a compelling cross-validated model of the Universe. Yet, two key pillars of this model -- dark matter and dark energy -- remain m…
Multiscale simulation of blood flow in brain arteries with an aneurysm
Leopold Grinberg, Vitali Morozov, Dmitry A. Fedosov +4
Interfacing atomistic-based with continuum-based simulation codes is now required in many multiscale physical and biological systems. We present the first results from coupled atom…
