[slurm-users] Priority access for a group of users

[Marcus Wagner]

Hi David,

as far as I know, you can use the PriorityTier (partition parameter) to 
achieve this. According to the manpages (if I remember right) jobs from 
higher priority tier partitions have precedence over jobs from lower 
priority tier partitions, without taking the normal fairshare priority 
into consideration.

Marcus
