[slurm-users] Node selection bitmap

I am currently developing a resource selection plugin and I have noticed
Slurm provides the selection plugin with a node bitmap.
The problem is that the bitmap provided is not consistent.
This means that depending on the number of tasks the bitmap provided
less nodes even if they are available. For example if there are 30
and the job has 20 tasks "--ntasks=20" Slurm will send a bitmap with 20
if the user sets "--nodes=1-30".
Is there any way for slurmctld to provide the selection plugin with a
bitmap excluding only the nodes are allocated to other jobs?
Thank you for your time,
