Not sure it will help, but you can specify:

bf_max_job_array_resv=#

to tell Slurm how many array elements to do forward reservations for.  It 
won't affect how many Slurm will start per cycle though so I suspect it's not 
a useful feature.

I was hoping the Slurm "Workload Characterization Key" (WCKey) feature would 
help, but it looks like it's only a way to label jobs for reporting purposes 
rather than making scheduling decisions on them.

I'm out of ideas sorry!

All the best,
Chris
