摘要:
A method, system, and program for managing escalating resource needs within a grid environment are provided. 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. If the required performance level is not met, then the discrete sets of resources are queried for available resources to meet the required performance level in an order designated by said hierarchy. Available resources in a next discrete set of resource from the hierarchy of discrete sets of resources are added to a virtual organization of resources handling the job within the grid environment. 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 mechanism to permit consolidation of storage subsystem volumes into larger, more easily managed volumes and an operating system device driver which includes a trap mechanism for intercepting calls from a host into logical unit devices that were previously consolidated into a single physical volume. A map converts such calls to a logical unit device into a corresponding offset in the single physical volume. A driver accesses the single physical volume with corresponding offsets to transfer data associated with a particular logical unit device. So, logical unit devices can be consolidated and reconsolidated to single physical volumes and other physical volumes without requiring changes to the operating system or its application software and without requiring application or host downtime.

The invention provides a method, apparatus and system for reducing power consumption involving data storage devices. One embodiment involves a process for storing data in a first memory, and in response to the first memory exceeding a first threshold, migrating the data from the first memory to a second memory. In response to the second memory exceeding a second threshold, the process then involves migrating the data from the second memory to the third memory, wherein the second memory is sized and configured to store data targeted for the third memory to intelligently maintain a portion of the third memory in an inactive state.

Peer-to-peer communications between vehicles providing warning of a collision or near-collision event and/or collision avoidance is controlled by otherwise underutilized air bag deployment processors in respective vehicles. Direction of reception of warning signals is used to selectively control relaying of warning signals at differentiated warning levels, collision avoidance actions and/or in-vehicle warning alarms to operators of vehicles in the vicinity of an event.

In a graphical user interface or other similar processing environment, functionality is provided that enables the selecting of multiple portions of non-contiguous content, and enables such functionality within the same application and also across different applications. Further, a “direct save” function is enabled that allows the user to directly save the multiple portions of selected content to a file. In addition, selected content portions can be categorized, and a mechanism is provided to allow the user to conveniently make use of these various categories for effective content viewing.

A method, system, and program for estimating future grid job costs by classifying grid jobs and storing results of processing grid job microcosms are provided. In general, a client side agent estimates future grid job costs by comparing a current grid job of a particular classification with a history of stored costs for other grid jobs of that customer of that particular classification. In particular, the grid client agent for a client system enabled to submit grid jobs to a grid provider that facilitates a grid environment, calculates a ratio of an application based metric to a grid provider metric for processing a particular grid job. Then, the grid client agent creates a table with an entry comparing the application based metric to a cost per grid provider metric for the grid provider based on the calculated ratio. Next, the grid client agent stores the table with the entry. Then, responsive to detecting a next grid job, the grid client agent estimates a cost for the grid provider to process the next grid job based on a particular number of application based metric operations required for the next grid job, translated by the ratio into the grid provider metric and multiplied by the cost per grid provider metric.

A method, system, and program for setting operation based resource utilization thresholds for resource use by a process are provided. An efficiency-based workload manager samples multiple actual resource use characteristics while a process executes, where the actual resource use characteristics designate a portion of a total amount of system resources available to the process that are utilized by the process at multiple times over a sampling period. Next, responsive to detecting the conclusion of the sampling period, the efficiency-based workload manager determines an operation based resource utilization threshold for the process based on a maximum resource use within the multiple samplings of actual resource use characteristics. Then, the efficiency-based workload manager stores the operation based resource utilization threshold for access by a workload manager, where the workload manager uses the operation based resource utilization threshold to restrict the process to resource use up to the operation based resource utilization threshold within an execution environment managed by the workload manager.

A method, system, and program for facilitating overall grid environment management by monitoring grid activity across disparate grid resources and distributing grid activity to decisional grid modules are provided. A grid workload controller within a computational grid environment monitors real-time grid activity at an application level from multiple disparate grid application environments. The grid workload controller then determines a selection of grid modules within the computational grid environment that require the real-time grid activity to make decisions about the management of the computational grid environment. The grid workload controller distributes the real-time grid activity to the selection of grid modules, wherein the selection of grid modules then make automated decisions within the grid environment to maintain performance requirements.

A method, system, and program for automatically building a locally managed virtual node grouping to handle a grid job requiring a degree of resource parallelism for execution within a grid environment are provided. The grid environment includes multiple resource nodes which are identified by physical location as physically disparate groups each managed by a grid manager. The grid managers include a grid virtual node grouping subsystem that enables a particular grid manager receiving a grid job that requires a particular degree of resource parallelism for execution to build a virtual node grouping of resources from across the grid environment and locally manage the resources included in the virtual node grouping. In particular, the particular grid manager accesses, from the other grid managers, a current availability and workload of each of the physically disparate resource nodes. The particular grid manager selects a selection of resource nodes to build into a virtual node grouping for executing the grid job. The virtual node grouping is built by the other grid managers enabling the particular grid manager to acquire temporary management control over the selection of resource nodes for a duration of the execution of the grid job within the virtual node grouping.
