[slurm-dev] Re: concurrent job limit
Eric, We find that the "honor system" frequently needs to be policed. We use SLURM's QOS and accounting systems to limit the number of concurrent cores, maximum running jobs, and maximum pending jobs. You may want to investigate this. With a QOS, you can apply limits per users (specifically cores), and with accounting you can apply limits per user or as a whole for a group (account).

[slurm-dev] Re: concurrent job limit
Job arrays can kind of be used for that: From http://slurm.schedmd.com/job_array.html: A maximum number of simultaneously running tasks from the job array may be specified using a "%" separator. For example "--array=0-15%4" will limit the number of simultaneously running tasks from this job array to 4.
