[slurm-users] Re: Randomly draining nodes

[Laura Hild via slurm-users]

Apologies if I'm missing this in your post, but do you in fact have a Prolog 
configured in your slurm.conf?

[slurm-users] Re: How does --nodes=min[-max] determine number of nodes to allocate?

[Renfro, Michael via slurm-users]

Not so much about the source, but in the sbatch documentation [1], I think the 
--begin and --nodes parameters might interact. And yes, this is semi-educated 
speculation on my part.

From the nodes= section, “The job will be allocated as many nodes as possible 
within the range specified and without delaying the initiation of the job.” So 
without specifying a begin time, the scheduler will look for the first 
available time it can schedule the minimum number of nodes requested. If it can 
find more nodes, up to the maximum requested, then you’d get a higher number of 
nodes at that time.

Hi,

I am trying to understand how Slurm determines the actual number of nodes to 
allocate to a job specified with –nodes=min[-max]

I’ve been trying to follow the source code through on Github – could anyone 
point me in the right area(s)/source files/functions to look at to understand 
the program logic behind this.

Many thanks in advance,

Declan
