Zero-sum game

It is conceivable to think of a Grid Scheduler as the mediator to a zero-sum game.  The number of resources do not change — not taking into account the hype that is cloud these days with elastic computing.  If the number of resources available to a scheduler and in turn the clients/players of the system is constant, the number of CPU’s that one client gets assigned directly affects the number of CPU’s that has been “taken” away from the pool of resources available to the second client.

As the total number of resources does not change, and one players action based on fairshare scheduling affects the number of resources that it gets assigned, one can conclude:

Based on client’s task submission strategy, a client realizes a utility that is directly a result of the number of resources it received – or got assigned to by the scheduler.
