let's say I want to submit a large batch job that should run on 8 nodes. I have two partitions, each holding 4 nodes. Slurm will now tell me that "Requested node configuration is not available". However, my desired output would be that slurm makes use of both partitions and allocates all 8 nodes.
A compute node can be a member of multiple partitions, this is how you can handle your case.
Suppose you have 4 nodes in part1 and 4 nodes in part2. Then you can create a new partition "partbig" which contains all 8 nodes.
You may want to configure restrictions on "partbig" if you don't want every user to submit to it, or configure a lower maximum time for jobs.
I hope this helps, Ole
