[slurm-users] extended list of nodes allocated to a job

[Alain O' Miniussi]

Hi,

I'm looking for a way to get the list of nodes where a given job is running in a uncompressed way.
That is, I'd like to have node1,node2,node3 instead of node1-node3.
Is there way to achieve that ?
I need the information outside the script.

Thanks

Given a job ID:

 

scontrol show hostnames $(scontrol show job some_job_id | grep ' NodeList=' | cut -d= -f2) | paste -sd,

 

Maybe there’s something more built-in than this, but it gets the job done.

Hi Alain,

I don't know if slurm can do that natively. python-hostlist, https://www.nsc.liu.se/~kent/python-hostlist/, may provide the functionality you need. I have used it in the past to generate a list of hosts that can be looped over.

Hope that helps.

Sean

Hi Sean,

A colleague pointed to me the following commands:

#scontrol show hostname x[1000,1009,1029-1031]
x1000
x1009
x1029
x1030
x1031
#scontrol show hostlist x[1000,1009,1029,1030,1031]
x[1000,1009,1029-1031]
#

“sinfo” can expand compressed hostnames too:

$ sinfo -n lm602-[08,10] -O NodeHost -h

lm602-08            

lm602-10            

$

I didn’t know that one! Thank you.
