[slurm-users] Job are pending when plenty of resources available

[Marcus Wagner]

Hi Mike,

but that would mean, that 409978 requests nearly the whole cluster. I'm 
wondering for what resources it waits.
Yet, there are nearly 32000 nodes idle. I would assume, such one node 
job would fit. But you are right, depends on the higher prio job.

Best
Marcus
