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…
On the Challenges of Energy-Efficiency Analysis in HPC Systems: Evaluating Synthetic Benchmarks and Gromacs
Rafael Ravedutti Lucio Machado, Jan Eitzinger, Georg Hager +1
This paper discusses the challenges encountered when analyzing the energy efficiency of synthetic benchmarks and the Gromacs package on the Fritz and Alex HPC clusters. Experiments…
Energy-aware operation of HPC systems in Germany
Estela Suarez, Hendryk Bockelmann, Norbert Eicker +19
