Right, so I have managed to get the nvidia tools installed and I can see
the files now:
root@zorn:~/slurm-23.02.3# find / -xdev -name libnvidia-ml.so
/usr/local/cuda-12.2/targets/x86_64-linux/lib/stubs/libnvidia-ml.so
/usr/lib/x86_64-linux-gnu/nvidia/current/libnvidia-ml.so
root@zorn:~/slurm-23.02.3# find / -xdev -name nvml.h
/usr/local/cuda-12.2/targets/x86_64-linux/include/nvml.h
and I build with:
root@zorn:~/slurm-23.02.3# ./configure --with-nvml=/usr/local/cuda-12.2
However the config.log seems odd:
root@zorn:~/slurm-23.02.3# grep nvml config.log
$ ./configure --with-nvml=/usr/local/cuda-12.2
configure:23416: checking for nvml.h

ac_cv_header_nvml_h=yes
ac_cv_lib_nvidia_ml_nvmlInit=yes
It seems to say it can't find nvml.h at first, but then sets
'ac_cv_header_nvml_h=yes'. I tried to run make anyway:
root@zorn:~/slurm-23.02.3# make 2>&1 | tee make.log
According to make.log, it looks like gpu_nvml.o was built without error:
root@zorn:~/slurm-23.02.3# grep nvml make.log
Making all in nvml

On the other hand, slurmd doesn't seem to load libnvidia-ml.so, as I
would have expected:

in the config file (but I see other
