Space-Time Parallel Direct Numerical Simulation of Rayleigh-Bénard Convection

Thomas Saupe, Thibaut Lunet, Mathis Bode +3

Rayleigh-Bénard convection (RBC) is a model for turbulent flow and challenging to simulate by direct numerical simulation (DNS). Adequate resolution of all relevant length scales r…

4D Parallelism Unlocks Exascale Bayesian Neural Networks for High-Fidelity Atmospheric Modeling

Deifilia Kieckhefen, Juan Pedro Gutiérrez Hermosillo Muriedas, Lars Helge Heyen +12

We present BEAST, the first-ever Bayesian Swin Transformer for atmospheric forecasting on 0.25 global resolution able to accurately quantify both aleatoric and epistemic un…

LongVU-TTT: Causal Test-Time Training for Visual Resampling in Long Video Understanding

Mahmoud Ahmed, Sameh Abdulah, Olatunji Ruwase +3

Long-video MLLMs must model temporal change before a limited visual-token budget removes most frame evidence. We introduce LongVU-TTT, which inserts a convolutional Test-Time Train…

Cross-Layer Energy Analysis of Multimodal Training on Grace Hopper Superchips

Mahmoud Ahmed, Sameh Abdulah, Olatunji Ruwase +4

Multimodal deep learning models enable joint learning across heterogeneous data sources, including text, images, and video, but their rapid scaling introduces significant memory an…

Deciphering boundary layer dynamics in high-Rayleigh-number convection using 3360 GPUs and a high-scaling in-situ workflow

Mathis Bode, Damian Alvarez, Paul Fischer +10

Turbulent heat and momentum transfer processes due to thermal convection cover many scales and are of great importance for several natural and technical flows. One consequence is t…

No sustained mean velocity in the boundary region of plane thermal convection

Roshan J. Samuel, Mathis Bode, Janet D. Scheel +2

We study the dynamics of thermal and momentum boundary regions in three-dimensional direct numerical simulations of Rayleigh-Bénard convection for the Rayleigh number range $10^5 \…
