+Abstract
+============
+
+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 practical domain sizes. This intensive requirement renders 
+traditional checkpointing methods ineffective due to the significant slowdown in 
+simulations while saving state data to disk. As we progress towards exascale and 
+GPU-driven High-Performance Computing (HPC) and confront larger problem sizes, the 
+choice becomes increasingly stark: to compromise data fidelity or to reduce resolution.
+To navigate this challenge, this study advocates for the use of in situ analysis and 
+visualization techniques. These allow more frequent data "snapshots" to be taken 
+directly from memory, thus avoiding the need for disruptive checkpointing. We detail 
+our approach of instrumenting NekRS, a GPU-focused thermal-fluid simulation code employing 
+the spectral element method (SEM), and describe varied in situ and in transit strategies 
+for data rendering. Additionally, we provide concrete scientific use-cases and report on 
+runs performed on Polaris, Argonne Leadership Computing Facility’s (ALCF) 44 Petaflop 
+supercomputer and Jülich Wizard for European Leadership Science (JUWELS) Booster, Jülich 
+Supercomputing Centre’s (JSC) 71 Petaflop High Performance Computing (HPC) system, 
+offering practical insight into the implications of our methodology.
