We were honored to have Olivier Schreiber from AMD present at the SIMULIA Americas Users Conference, May 3-4, 2023 in Novi, Michigan.

Abstract: Users of SIMULIA Abaqus Standard and Explicit should be able to rely on significant performance improvements with each new generation of system CPU. Systems powered by dual 32-core and 64-core 4th Gen AMD EPYC™ processors demonstrate outstanding generational performance uplifts compared to dual 32-core and 64-core 3rd Gen AMD EPYC processors across a variety of SIMULIA Abaqus Standard and Explicit benchmarks. In this talk we will present the latest performance results and show how multi-node runs exhibit scaling for both Standard and Explicit. SIMULIA Abaqus upgrade from 2022 to 2023 performance benefits will also be covered. Lastly, we will offer recommendations for Hybrid-MPI mode run configurations with number of ranks equal to number of NUMA domains, and number of threads equal to the number of cores per NUMA domain within other constraints.

Bio: Olivier Schreiber has been a High-Performance Computing Applications Engineer at HP, SGI, HPE and now AMD since 2001 and contracted at SpaceX, Virgin Orbit and Google X.  Before that, he was at Boeing North American and McDonnell Douglas as a Principal Engineer/Scientist/Computing Specialist.  Earlier, he was a Nastran developer at The MacNeal-Schwendler Corporation.  Olivier holds an MS and PhD in Aerospace Engineering from the Georgia Institute of Technology. For his thesis, he developed a time marching multiprocess interactive Computational Fluid Dynamics code with graphical 3D visualization and user interface which led to five publications. His initial engineering diploma is from France's Supaero.
