[slurm-users] hierarchies/dependencies between QoSs

[Sebastian Schmutzhard-Höfler]

Hi,

is there a way to have hierarchies/dependencies between different QoS's, 
except from preemption?

Is it possible to change the qos of a running job?

We have qos=gpus2, qos=gpus4 and qos=gpus6 (allowing a certain maximal 
total number of gpus for the user). I want that the running/pending 
qos=gpus2 jobs are converted to qos=gpus4 jobs when a qos=gpus4 job is 
submitted, and also, when qos=gpus4 jobs are already running, new 
qos=gpus2 jobs are subimtted automatically as qos=gpus4 jobs.

Thanks,

Sebastian
