Pantheon

No. Pantheon automatically detects CUDA, ROCm/HIP, or mock mode. You run the pantheon command directly without passing --platform.

The Debian package is the simplest path for Ubuntu/Debian. A portable release bundle is available for RHEL-family systems and other Linux distributions, installed via ./install.sh.

Run sudo apt-get remove pantheongpu for package-managed files, plus curl -fsSL https://pantheongpu.com/uninstall.sh | sudo sh to also remove runtime-created files and the current user's compiled workload cache. This leaves CUDA, ROCm, system compilers, and benchmark reports outside Pantheon's directories untouched.

Yes, you can run pantheon --test baseline_metrics --duration 10 for a short hardware inventory test, which gives baseline metrics without lengthy stress runs.

First-run workload builds are cached under ${XDG_CACHE_HOME:-$HOME/.cache}/pantheongpu/builds/. You can override this with the PANTHEON_BUILD_CACHE_DIR environment variable.

Yes, Pantheon includes a public performance database for live benchmarks and comparisons, and results are stored locally for your own comparisons.
