[Mauiusers] fairshare in maui

I may be confused by the differences between moab and maui, but isn't "Moab supports arbitrary depth hierarchical fairshare based on a share tree" what Jan is looking for?  This is described in 6.3.4 of the moab manual.

Hi Jan,

The short answer is 'no'. The fairshare in maui is not hierarchical.  As Gabe notes, you can use 'accounts' to correspond to projects or experiments, but it's still a flat rather than hierarchical share.  I guess you could readily take a logical hierarchical set of shares and convert them to a flat set for the 'leaves' but you would not get the same sort of fairshare between peer nodes in the hierarchy that you would with a 'proper' hierarchical fairshare model.
