Deciphering boundary layer dynamics in high-Rayleigh-number convection using 3360 GPUs and a high-scaling in-situ workflow
Direct numerical simulations of Rayleigh-Benard convection at Ra=10^12 on 3,360 GPUs, combined with an ASCENT-based in-situ workflow, deliver time-resolved boundary-layer visualization at manageable overhead.
