Integration and Performance of New Technologies in the CMS Simulation [Slides]
K. Pedro · 2019
CMS upgrade simulation for HL-LHC may be 2–3×slower than Run 2. CMS integration tests of GeantV met all goals: 1. Co-development ensured compatible threading models & interfaces, 2. Similar speedup measured in full experiment software framework, and 3. Efficient path to integration was established. GeantV prototype is a useful demonstrator. The next step is a GeantX project for HPCs w/ GPUs.
