Project Description
Whenever a computer supports two or more activities, it needs to schedule them so that resources are shared appropriately. Conventional schedulers allow some users to exploit the system and take a large part of the machine's resources and make it is easy for a user to accidentally or intentionally create a program that takes over large amounts of the machine time. The Fair Share Scheduler overcomes these problems and allows computer resources to be fairly and precisely shared between users, programs or organisations. It was originally motivated by the challenges of supporting a large student and staff population on a single machine which ground to a halt at assignment deadlines until FairShare forced the fair sharing of resources to all users.
Fair Share has been commercialised by Aurema Pty Ltd (formerly Softway). It has been licenced for global deployment to Sun Microsystems, Compaq, Siemens[tm], SGI[tm], Cray[tm] and other leaders of server technology.
