Anonymized Summary:

A user reports a CUDA-related error in MATLAB when running on node max-hzgg014 (part of the Maxwell cluster). The error suggests a potential issue with CUDA drivers or compatibility.

Possible Solution:

  1. Check MATLAB-CUDA Compatibility:
  2. MATLAB requires specific CUDA versions. Verify if the installed CUDA version on max-hzgg014 matches MATLAB’s requirements.

  3. Use module avail cuda to list available CUDA versions and load the correct one (e.g., module load cuda/11.2).

  4. Node-Specific GPU Hardware:

  5. max-hzgg014 is part of the HPC Gateway GPU nodes (H200-NVL). These nodes enforce commercial-use-only software policies, and MATLAB is not available on partitions hpcgwgpu or compgpu (see 2025-09-29 update).

  6. If the job is running on compgpu or hpcgwgpu, MATLAB will fail due to licensing restrictions.

  7. Alternative Partitions:

  8. Run MATLAB on non-HPC Gateway partitions (e.g., allgpu or standard CPU nodes) where MATLAB is supported.

  9. Example: bash #SBATCH --partition=allgpu #SBATCH --constraint="V100|P100" # Use older GPUs if needed

  10. Debugging Steps:

  11. Test CUDA functionality outside MATLAB: bash module load cuda/11.2 nvidia-smi # Check GPU visibility
  12. Verify MATLAB’s GPU support: matlab gpuDevice # Check if MATLAB detects the GPU
