The invention relates to controlling the participation and performance management of a distributed set of resources in a grid environment. The control is achieved by forecasting the behavior of a group of shared resources, their availability and quality of their performance in the presence of external policies governing their usage, and deciding the suitability of their participation in a grid computation. The system also provides services to grid clients with certain minimum levels of service guarantees using resources with uncertainties in their service potentials.

A technique for hot deploying/redeploying applications in a grid computing environment to improve operating efficiency and reduced overhead. In one example embodiment, this is accomplished by notifying a client application manager associated with each of one or more grid nodes about a type of data transfer protocol to use upon receiving a new version of an application release bundle by a repository server. The new version of the application release bundle is then hot deployed/redeployed on running one or more application servers in the associated grid using an appropriate hot deployment plug-in based on the data transfer protocol by each client application manager.

A hybrid of grid-based and graph-based search computations, together with provision of a sparse search technique effectively limited to high-probability candidate nodes provides accommodation of path constraints in an optimization search problem in substantially real-time with limited computational resources and memory. A grid of best cost (BC) values are computed from a grid of map cost (MC) values and used to evaluate nodes included in the search. Minimum segment/vector length, maximum turn angle, and maximum path length along a search path are used to limit the number of search vectors generated in the sparse search. A min-heap is preferably used as a comparison engine to compare cost values of a plurality of nodes to accumulate candidate nodes for expansion and determine which node at the terminus of a partial search path provides the greatest likelihood of being included in a near-optimal complete solution, allowing the search to effectively jump between branches to carry out further expansion of a node without retracing portions of the search path. Capacity of the comparison engine can be limited in the interest of expediting of processing and values may be excluded or discarded therefrom. Other constraints such as approach trajectory are accommodated by altering MC and BC values in a pattern or in accordance with a function of a parameter such as altitude or by testing of the search path previously traversed.
