ClusterBench: A Framework for Cluster-Wide Continuous Benchmarking and Regression Testing
Aditya Ujeniya, Jan Eitzinger, Thomas Gruber +2
Data centers need tooling that validates an entire installation rather than individual nodes, at acceptance and at regular intervals thereafter. This requires dispatching identical…
Wattlytics: A Web Platform for Co-Optimizing Performance, Energy, and TCO in HPC Clusters
Ayesha Afzal, Georg Hager, Gerhard Wellein
The escalating computational demands and energy footprint of GPU-accelerated computing systems complicate informed design and operational decisions. We present the first release of…
Architectural Trade-offs in the Energy-Efficient Era: A Comparative Study of power-capping NVIDIA H100 and H200
Aditya Ujeniya, Jan Eitzinger, Georg Hager +1
Modern NVIDIA GPUs like the H100 (HBM2e) and H200 (HBM3e) share similar compute characteristics but differ significantly in memory interface technology and bandwidth. By isolating…
AI Application Benchmarking: Power-Aware Performance Analysis for Vision and Language Models
Martin Mayr, Sebastian Wind, Lukas Schröder +4
Artificial Intelligence (AI) workloads drive a rapid expansion of high-performance computing (HPC) infrastructures and increase their power and energy demands towards a critical le…
