A digital data file storage system is disclosed in which original data files to be stored are dispersed using some form of information dispersal algorithm into a number of file “slices” or subsets in such a manner that the data in each file share is less usable or less recognizable or completely unusable or completely unrecognizable by itself except when combined with some or all of the other file shares. These file shares are stored on separate digital data storage devices as a way of increasing privacy and security. As dispersed file shares are being transferred to or stored on a grid of distributed storage locations, various grid resources may become non-operational or may operate below at a less than optimal level. When dispersed file shares are being written to a dispersed storage grid which not available, the grid clients designates the dispersed data shares that could not be written at that time on a Rebuild List. In addition when grid resources already storing dispersed data become non-available, a process within the dispersed storage grid designates the dispersed data shares that need to be recreated on the Rebuild List. At other points in time a separate process reads the set of Rebuild Lists used to create the corresponding dispersed data and stores that data on available grid resources.

The grid resources may include resources from, e.g., other logical partitions within the logically partitioned system, logical partitions from other logically partitioned systems, another type of system, a cluster, and the like. Further, one or more of the systems associated with the grid may include on-demand resources that are also available to supplement resources based upon the demands of the client. Embodiments may also monitor resource usage by the client and meter billable usage of the grid resources and / or on-demand resources based upon agreements between service providers and clients.

A method, system, and program for dynamic grid job distribution from any resource within a grid environment. Multiple resources enabled to handle grid jobs are connected via at least one network within a grid environment. Each of the multiple resources is enabled to distribute an availability and ability to handle grid jobs within the grid environment. Each of the multiple resources is also enabled to access the availability and ability to handle grid jobs of all of the other resources within the grid environment. The distribution of and access to current information may be organized as a hierarchical resource directory system or as a peer-to-peer resource distribution system. Further, resources within the grid environment are also enabled to receive a grid job and a job object, as a receiving resource. The job object received at a receiving resource describes at least one requirement for the grid job submitted to the receiving resource. The receiving resource determines the most suitable resource to handle the job from among the grid resources, wherein the ability to handle grid jobs by the most suitable resource meets the at least one requirement for the grid job and the most suitable resource indicates an availability to receive the grid job. The receiving resource then controls submission of the job to the most suitable resource for handling the job.

A job is submitted into a first selection of resources in a grid environment from among a hierarchy of discrete sets of resources accessible in the grid environment. Discrete sets of resources may include locally accessible resources, enterprise accessible resources, capacity on demand resources, and grid resources. The performance of the first selection of resources is monitored and compared with a required performance level for the job.

In particular, the virtual organization of resources may include the first selection of resources and the added resources which are distributed across heterogeneous systems. If capacity on demand resources are allocated and added to the virtual organization, then the capacity on demand resources are deallocated when no longer needed.

A Grid Proxy Architecture for Network Resources (GPAN) is proposed to allow Grid applications to access resources shared in communication network domains. GPAN bridges Grid services serving user applications and network services controlling network devices through its proxy functions such as resource data and management proxies. Working with Grid resource index and broker services, GPAN employs distributed network service peers (NSP) in network domains to discover, negotiate and allocate network resources such as bandwidth for Grid applications. An elected master NSP is the unique Grid node that runs GPAN and represents the whole network to share network resources to Grids without Grid involvement of network devices. GPAN provides the Grid Proxy service (GPS) to interface with Grid services and applications, and the Grid Delegation service (GDS) to interface with network services to utilize network resources. Resource-based XML messaging is employed for the GPAN proxy communication.
