226. Automated Metadata Collection, Standardization, and FAIR Publication of HPC Performance Data in NFDIxCS

10/2/26, 9:00 AM

Abstract

Traces and profiles produced by HPC tools such as Score-P and CUBE are essential for performance analysis and optimization. However, these datasets are rarely shared in a reusable form because important contextual information is often missing. Details about the hardware, software environment, application configuration, and scheduler settings are required to interpret and reproduce an...

230. Checkpoint-Based State Comparison for Localizing Correctness Regressions in Scientific Codes

10/2/26, 9:30 AM

Abstract

Performance optimization of scientific and high-performance computing (HPC) applications frequently introduces subtle behavioral changes that go unnoticed until they manifest as incorrect scientific results. Detecting whether such changes alter computed state, and precisely where in the code and iteration space a divergence first occurs, remains a largely manual and time-consuming...

225. Parallel Scalability Analysis of a Hierarchical Adaptive Mesh Refinement Workflow

10/2/26, 10:00 AM

Abstract

Computational fluid dynamics underpins aerospace development. However, accurate simulation of full aircraft configurations at in-flight speeds requires large grids and, hence, massive parallelism on high performance computers. For such applications, adaptive mesh refinement (AMR) allows to lower the computational effort by refining the mesh at locations of interest. As this happens during the...
