Managing escalating resource needs within a grid environment

A computer program product for managing escalating resources needs of a job submitted in a grid environment, the computer program product comprising:

• one or more computer-readable tangible storage devices;
• program instructions, stored on at least one of the one or more storage devices, to organize, by a grid management system, at least one resource into a hierarchy of discrete sets of resources comprising a plurality of local resources, a plurality of capacity on demand resources, and a plurality of external grid resources, said grid management system for managing said at least one resource from a grid environment comprising a plurality of computing systems each comprising said at least one resource and communicatively connected over a network to share each said at least one resource through at least one grid service;
• program instructions, stored on at least one of the one or more storage devices, to receive a plurality of separate job requests from a plurality of client systems over said network at a grid management system;
• program instructions, stored on at least one of the one or more storage devices, to submit a particular job from among said plurality of jobs received at a said grid management system from a particular client system from among said plurality of client systems to a virtual organization comprising a first selection of said plurality of local resources from among said hierarchy of discrete sets of resources;
• program instructions, stored on at least one of the one or more storage devices, to monitor a performance level of said virtual organization handling said particular job;
• program instructions, stored on at least one of the one or more storage devices, to compare said performance level of said virtual organization with a performance requirement for said particular job;
• program instructions, stored on at least one of the one or more storage devices, responsive to a performance level of said virtual organization not meeting a required performance level for said particular job, to query said hierarchy of discrete sets of resources in an order designated by said hierarchy from among said second selection of capacity on demand resources and said third selection of external grid resources to meet said required performance level for said particular job;
• and
• program instructions, stored on at least one of the one or more storage devices, responsive to identifying at least one available additional resource from said hierarchy of discrete sets of resources, to add said at least one available additional resource to said virtual organization of said resources handling said particular job within said grid environment, such that escalating resource needs of said particular job in said grid environment are managed by hierarchically adding resources from discrete sets of resources within said grid environment to said virtual organization of said resources already handling said particular job.
