- PantheonGPU stress-tests compute, memory, cache, interconnect, and power through focused workloads that capture telemetry and retain results for later comparison.
- Version 1.0.14 ships as a Debian package for Ubuntu and Debian systems, with an install.sh-based portable bundle covering RHEL, Fedora, Rocky Linux, and AlmaLinux.
- The tool auto-detects CUDA, ROCm/HIP, or mock mode at runtime, requiring no explicit --platform flag from the user.
- First-run workload builds are cached under ${XDG_CACHE_HOME:-$HOME/.cache}/pantheongpu/builds/, with PANTHEON_BUILD_CACHE_DIR available as an override.
- Complete removal preserves CUDA, ROCm, system compilers, and benchmark reports stored outside the install and cache directories.
Why it matters: For engineers maintaining heterogeneous GPU fleets, PantheonGPU's automatic CUDA/ROCm/mock detection eliminates the need to juggle separate vendor-specific stress suites — one binary covers NVIDIA, AMD, and offline hardware simulation. Build caching under $XDG_CACHE_HOME/pantheongpu/builds/ skips recompilation on repeat runs, while the uninstall path leaves system CUDA/ROCm installs and benchmark reports untouched for clean dev-environment teardowns.
