234. Performance-Aware Software Engineering: Utilizing Analysis Tools in the Development Workflow of Aerospace Applications

10/1/26, 10:20 AM

Abstract

This presentation provides an overview of the use of tools for verifying parallel performance and correctness at the DLR institute in Dresden.
Typical use cases, examples of identified bottlenecks and their performance impact as well as problems uncovered are shown for both individual and coupled applications.
Additionally, automated builds are demonstrated for coupled problems involving...

227. A Diagnostic Tool for Phase-Aware Resource Allocation in Malleable HPC Workloads

10/1/26, 10:50 AM

Abstract

As these systems become larger and more complex, managing efficient utilization of resources becomes increasingly challenging.
While de-facto job schedulers such as Slurm and Flux improve resource utilization at various levels, for example by enabling job concurrency, the traditional static allocation of computational resources at job start compels users to provision for peak demand across...

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

10/1/26, 11:20 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...
