Some servers have accelerators and you'll want their analysis tools installed as well: e.g., on Intel GPU servers, the intel-gpu-tools package; on NVIDIA, nvidia-smi. On cloud instances, adding Mbytes to the base server image can add seconds, or fractions of a second, to instance deployment time. This list is a minimum.
