Description
At INFN-T1 several competing groups submit their payloads to the HTCondor pool with a high level of heterogeneity. In particular, the same group can submit both multi core and single core jobs, and the ratio between these two can change quite rapidly; this and other unpredictable user side behaviours can make difficult for HTCondor administrators to provide user groups with a satisfactory fair share of the available computing resources.
As an attempt to reduce usage imbalances between different user groups, a system to self adjust disparities has been developed and it is being used with good results so far.
