Abstract

The International Journal of High Performance Computing Applications, Volume 40, Issue 2, Page 123-141, March 2026.
We present a thorough performance and energy consumption analysis of the LULESH proxy application in its OpenMP and MPI variants on two different clusters based on Intel Ice Lake (ICL) and Sapphire Rapids (SPR) CPUs. We first study the strong scaling and ...
