1. A computer-implemented method for determining a capacity of a grid environment to handle a job specified by a virtual job request, comprising: receiving, from a client system, a virtual job request for processing a job within a grid environment at a bid controller via a network; determining a total required workload for said virtual job request; and calculating a capacity of said grid environment to handle said total required workload, wherein a bid is enabled to be automatically generated responsive to said virtual job request based on said capacity of said grid environment to handle said total required workload.
