abstract = {Mathis Bode, Jens Henrik Göbbert, Jonathan Windgassen and
their collaborators from Argonne National Laboratory (USA)
have won the Best Paper Award for their paper “Scaling
Computational Fluid Dynamics: In Situ Visualization of NekRS
using SENSEI”. It was presented at the “ISAV 2023: In
Situ Infrastructures for Enabling Extreme-scale Analysis and
Visualization” workshop, which took place in conjunction
with the SC23 on 13 November 2023 in Denver, Colorado,
USA.The team describes in their paper a novel pipeline for
in situ and in transit visualization and analysis utilizing
SENSEI, ADIOS2, and ParaView over Python. The aim is to
solve the dilemma having to choose between data accuracy or
decreasing the resolution for Computational Fluid Dynamics
on GPU-powered HPC systems. Their approach makes more
regular data snapshots directly from memory and thus
bypasses the pitfalls of checkpointing. The application
NekRS is a GPU-centric thermal-fluid simulation, which
showcases diverse in situ and in transit strategies.
Experiments on the Polaris and JUWELS Booster supercomputers
were conducted to demonstrate real-world implications, which
offered crucial insights how efficient data management can
be achieved without compromising accuracy.},
