[slurm-users] How to set association factor in Multifactor Priority

    I found that a new "Association Factor" is introduced in 19.05 to be part of Job_priority calculation. Can I set it for each SLURM account so job priority can be differentiated based on job accounts?

    Association Factor
    Each association can be assigned an integer priority. The larger the number, the greater the job priority will be for jobs that request this association. This priority value is normalized to the highest priority of all the association to become the association factor.

    Job_priority =
	site_factor +
	(PriorityWeightAge) * (age_factor) +
	(PriorityWeightAssoc) * (assoc_factor) +
	(PriorityWeightFairshare) * (fair-share_factor) +
	(PriorityWeightJobSize) * (job_size_factor) +
	(PriorityWeightPartition) * (partition_factor) +
	(PriorityWeightQOS) * (QOS_factor) +
	SUM(TRES_weight_cpu * TRES_factor_cpu,
	    TRES_weight_<type> * TRES_factor_<type>,
	- nice_factor

Thank you!
