Attachments: patch to scrub non-alnums

patch to scrub non-alnums

Hi,

I've been looking at the AutoDetect=nvml functionality.  In our case we have a graphics card with parentheses in the name, so this results in the automatic gres name "nvidia_titan_x_(pascal)" with the parentheses included.  We also have Titan X and Titan Xp cards so I don't want to rely on a substring match of just titan_x.

Example graphics card names from nvidia-smi -L output:
"NVIDIA TITAN X (Pascal)", "NVIDIA GeForce GTX TITAN X", "NVIDIA TITAN Xp"


I've applied a local patch (attached) that enhances gpu_common_underscorify_tolower to remove all non-space and non-alnum characters.

I don't think this is a massive priority to change in Slurm, but it's possible this bug report will be helpful to another admin.

Thanks,
Ben.

Hello, I would like to join this request as we have the same issue. This is the name we currently obtain using nvml:

- nvidia_titan_x
- tesla_p100-pcie-12gb
- nvidia_titan_rtx
- nvidia_geforce_rtx_2080_ti
- tesla_v100-pcie-32gb
- nvidia_geforce_rtx_3080
- nvidia_geforce_rtx_3090
- nvidia_rtx_a5000
- nvidia_rtx_a5500
- nvidia_rtx_a6000
- nvidia_a100-pcie-40gb
- nvidia_a100_80gb_pcie
- nvidia_geforce_rtx_4090
- nvidia_rtx_5000
- nvidia_h100_nvl
- nvidia_h200_nvl
- nvidia_rtx_pro_6000_blackwell
- nvidia_geforce_rtx_5090

We would expect something coherent such as vendor_architecture_model_interface_vram
