PANTHEON

Universal GPU Stress & Diagnostics Suite

Latest Release Live Benchmarks

Why Pantheon?

Pantheon is a cross-platform (CUDA/ROCm) stress testing tool designed to isolate and hammer specific GPU subsystems. Unlike generic benchmarks, Pantheon targets specific silicon limits to expose hardware degradation, thermal throttling, and architecture bottlenecks.

  • VRAM & Infinity Fabric --- Target Memory/GDDR memory and interconnects with aggressive crosstalk patterns to detect bit flips and signal integrity loss.

    Test: memory_write_agg, memory_tsv_thrasher

  • Physical Matrix Cores --- Push hardware Tensor and Matrix cores to their absolute thermal limits using universal FP16/WMMA intrinsics.

    Test: mma_virus, tensor_virus

  • VRM Transients (dI/dt) --- Oscillate maximum load at 10Hz to induce high current transients, testing your power supply and voltage regulators.

    Test: pulse_virus, voltage

  • MMU & TLB Avalanche --- Force near 100% Translation Lookaside Buffer misses with random page-boundary jumps to choke hardware page-table walkers.

    Test: tlb_avalanche

  • ECC & RAS Validation --- Continuously read pristine patterns to expose the latency jitter of active ECC scrubbing and silent data corruption.

    Test: ras_validator

  • Hardware Scheduler --- Spam micro-kernels across 64 concurrent streams to force the GPU dispatcher into multiplexing mode and trigger context switch locks.

    Test: scheduler

Quick Start

The Debian package is the simplest installation path for Ubuntu and Debian systems.

1. Install prerequisites

Install the basic build tools:

sudo apt-get update
sudo apt-get install -y make g++

Then install the compiler for your GPU platform. You only need one:

sudo apt-get install -y nvidia-cuda-toolkit

sudo apt-get install -y hipcc

2. Install Pantheon

Download and install the latest Debian package:

VERSION=1.0.12
wget "https://github.com/saqibkh/pantheongpu_website/releases/download/v${VERSION}/pantheongpu_${VERSION}_amd64.deb"
sudo apt install "./pantheongpu_${VERSION}_amd64.deb"

To uninstall the Debian package later:

sudo apt-get remove pantheongpu

3. Verify the installation

Run a short hardware inventory test:

pantheon --test baseline_metrics --duration 10

Then run a targeted stress test on GPU 0:

pantheon --test fp64_virus --duration 30 --gpu 0

Note

Pantheon automatically detects CUDA, ROCm/HIP, or mock mode. Run the pantheon command directly; you do not need to pass --platform cuda.

Completely remove Pantheon

The native package command above removes Pantheon's package-managed files. To also remove runtime-created files and the current user's compiled workload cache—or to remove a portable installation on RHEL, Fedora, Rocky Linux, AlmaLinux, or another Linux distribution—run:

curl -fsSL https://pantheongpu.com/uninstall.sh | sudo sh

This leaves CUDA, ROCm, system compilers, and benchmark reports stored outside Pantheon's installation and cache directories untouched.

Alternative: install from the release bundle

The release bundle contains the Debian package and an install.sh helper for RHEL-family and other Linux distributions.

VERSION=1.0.12
wget "https://github.com/saqibkh/pantheongpu_website/releases/download/v${VERSION}/pantheongpu_${VERSION}_amd64.tar.gz"
tar -xzf "pantheongpu_${VERSION}_amd64.tar.gz"
cd "pantheongpu_${VERSION}_amd64"
sudo apt install "./packages/pantheongpu_${VERSION}_amd64.deb"

Uninstall a Debian package installation with:

sudo apt-get remove pantheongpu

On RHEL-family and other Linux systems, install the portable bundle with sudo ./install.sh. Remove that installation with:

sudo rm -f /usr/local/bin/pantheon && sudo rm -rf /opt/pantheongpu

Use the complete-removal command above if you also want to clear the current user's compiled workload cache.

Build cache

First-run workload builds are cached under ${XDG_CACHE_HOME:-$HOME/.cache}/pantheongpu/builds/. Set PANTHEON_BUILD_CACHE_DIR to choose another writable cache directory.
