ROCm & AMD GPU Computing Skill

Hardware

• GPU: AMD Radeon RX 6800 XT (Navi 21)
• VRAM: 16GB
• Architecture: gfx1030
• Kernel: 6.8.0-55-generic (with amdgpu-dkms)

Installed ROCm Components

• ROCm 6.3.2
• rocminfo
• rocm-smi
• hip-runtime-amd
• miopen-hip
• rocblas
• rocfft
• rocrand

Essential Commands

GPU Monitoring

rocm-smi                           # GPU status
rocm-smi --showproductname         # GPU info
rocm-smi --showpid                 # Show processes
rocminfo                           # Detailed ROCm info

Environment Variables

# Add to ~/.bashrc for permanent setup
export PATH=/opt/rocm/bin:$PATH
export LD_LIBRARY_PATH=/opt/rocm/lib:$LD_LIBRARY_PATH

PyTorch with ROCm

# Install PyTorch for ROCm
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm6.0

# Verify GPU access
python -c "import torch; print(torch.cuda.is_available()); print(torch.cuda.get_device_name(0))"

Docker with ROCm

docker run -it --device=/dev/kfd --device=/dev/dri --group-add video rocm/pytorch:latest

Performance Tuning

• Set HSA_OVERRIDE_GFX_VERSION=10.3.0 for compatibility
• GPU temperature: Check with rocm-smi (normal <85°C)
• Power limit: 264W (default)

Common Issues

• "No ROCm-capable GPU": Check kernel is 6.8.0-55, not 6.17
• Missing libraries: Ensure /opt/rocm/lib is in LD_LIBRARY_PATH
• Permission denied: User must be in 'render' and 'video' groups
