[slurm-users] Questions about SLURM configure options

[Elliott Slaughter]

Hi,

I have some questions about SLURM configuration options:

--with-pmix

I was confused about this because I thought that SLURM had its own first-party PMIx implementation, but I can't see a configuration option to control it. (And also, building without this option does not appear to generate a PMIx library.)

I was going to build against https://github.com/openpmix/openpmix, is that how people normally do this?

--with-nvml

Is this required for GPU binding, or does it do something else? What would I lose if I don't use this?

--with-hwloc

Similarly, I know what hwloc does, but what specific impact does this have on SLURM? Do I lose CPU core binding if I don't compile this?

Thanks.

Oh, and also, does it matter if hwloc itself is built against CUDA/NVML or not? Will SLURM take advantage of that functionality if available, and if so what capabilities does it add?

Elliot,

The proper use of `--with-pmix` is documented at https://slurm.schedmd.com/mpi_guide.html

I don't know anything about your other questions.
