Automatically building a locally managed virtual node grouping to handle a grid job requiring a degree of resource parallelism within a grid environment

A system for building virtual node groupings within a grid environment, comprising:

• a grid environment comprising a plurality of resource nodes identified in physically disparate groups each managed by one from among said plurality of grid managers;
• a particular grid manager from among said plurality of grid managers that locally manages a first selection of resource nodes from among said plurality of resource nodes within a particular physical location of said grid environment;
• said particular grid manager further comprising:
• means for detecting a grid job that requires a particular degree of parallelism for execution within said grid environment;
• means for accessing, from said plurality of grid managers, a current availability and workload of said plurality of resource nodes within said grid environment;
• means for selecting a second selection of resource nodes from among said plurality of resource nodes to build into a virtual node grouping for executing said grid job;
• and
• means for building said virtual node grouping by enabling said particular grid manager to acquire temporary management control over said second selection of resource nodes for a duration of execution of said grid job within said virtual node grouping.

A computer program product, residing on a computer readable medium, for building virtual node groupings within a grid environment, comprising:

• means for enabling detection of a grid job at a particular grid manager from among a plurality of grid managers within a grid environment, wherein said grid job requires a particular degree of parallelism for execution, wherein a plurality of resource nodes within said grid environment are identified in physically disparate groups each managed by one from among said plurality of grid managers, wherein said particular grid manager locally manages a first selection of resource nodes from among said plurality of resource nodes within said grid environment within a particular physical location;
• means for controlling access, from said plurality of grid managers, a current availability and workload of said plurality of resource nodes within said grid environment;
• means for controlling selection of a second selection of resource nodes from among said plurality of resource nodes to build into a virtual node grouping for executing said grid job;
• and
• means for controlling the building of said virtual node grouping by enabling said particular grid manager to acquire temporary management control over said second selection of resource nodes for a duration of execution of said grid job within said virtual node grouping.
