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…
tinyMD: A Portable and Scalable Implementation for Pairwise Interactions Simulations
Rafael Ravedutti L. Machado, Jonas Schmitt, Sebastian Eibl +6
This paper investigates the suitability of the AnyDSL partial evaluation framework to implement tinyMD: an efficient, scalable, and portable simulation of pairwise interactions amo…
Kerncraft: A Tool for Analytic Performance Modeling of Loop Kernels
Julian Hammer, Jan Eitzinger, Georg Hager +1
Achieving optimal program performance requires deep insight into the interaction between hardware and software. For software developers without an in-depth background in computer a…
Performance analysis of the Kahan-enhanced scalar product on current multi- and manycore processors
Johannes Hofmann, Dietmar Fey, Michael Riedmann +3
We investigate the performance characteristics of a numerically enhanced scalar product (dot) kernel loop that uses the Kahan algorithm to compensate for numerical errors, and desc…
Automatic Loop Kernel Analysis and Performance Modeling With Kerncraft
Julian Hammer, Georg Hager, Jan Eitzinger +1
Analytic performance models are essential for understanding the performance characteristics of loop kernels, which consume a major part of CPU cycles in computational science. Star…
