Re: [slurm-users] How to set default partition in slurm configuration

2023-01-25 Thread Diego Zuccato

Hi Xaver.

Just add "Default=Yes" to the definition of the partition you want to 
have as default. See

https://slurm.schedmd.com/slurm.conf.html#OPT_Default

If you just want Slurm select any partition that maches user's requests, 
you can use

JobSubmitPlugins=all_partitions

Dear slurm-user list,

I am aware that this question sounds very simple and it should be
resolved by just taking one look at the documentation, but for some
reason I am unable to find where I can set the default partition in the
slurm configuration.

For me it feels like simply the last added configuration becomes
automatically the default configuration, but I might be wrong in this
assessment of the situation. However, I would prefer just setting a key
instead of fiddling around with the positioning of partition definitions.

I only found reference to the "default partition" in `JobSubmitPlugins`
and this might be the solution. However, I think this is something so
basic that it probably shouldn't need a plugin so I am unsure.

Can anyone point me towards how setting the default partition is done?

Best regards,
Xaver Stiensmeier

[slurm-users] GPU: MPS vs Sharding

2023-01-25 Thread Ward Poelmans

Hi,

Slurm 22.05 has a new thing called GPU sharding that allows a single GPU to be 
used by multiple jobs at once. As far as I understood the major difference with 
the MPS approach is that this should generic (not tied to NVidia technology).

Has anyone tried it out? Does it work well? Any caveats or downsides compared 
to MPS?

Thanks,


Ward
