I’ve created a setup guide for Raptor Talos II secure workstations with IBM Power9 processors with NVIDIA GPUs here: GitHub - edowson/raptor-talos-ii-power9-technote: Setup guides for Raptor Talos II Secure Workstation based on IBM's Power9 CPU.
This guide is mainly aimed at users who want to setup an IBM Power9-based system with NVIDIA GPUs for AI, machine learning and robotics software development.
