WebbSLURM implements another factor of fairness such that not only the Raw Usage of an account is used to calculate the FairShare, but also the Raw Usage of its parent (i.e. the sum of all siblings). This allows that accounts of different parents with the same charged usage and the same shares, get different FairShare due to their sibling accounts. http://www.hpc.iitkgp.ac.in/HPCF/slurmcoord
