摘要:
A method, apparatus, and article of manufacture are provided to support security in a distributed grid computer cluster. Each non-node root node in the cluster is configured with a local security agent, and the root node is configured with a security controller to manage each of the security agents of each non-root node. The security agent of each non-root node is in communication with an associated configuration file that contains data private to the respective non-root node, to allow the security agent to manage security local to the node. The security controller of the root node is in communication with a controller configuration file that contains data that applies to all security agents in the grid cluster, to allow the controller to manage the security agents.

Embodiments of the invention relate to a container with one or more secondary objects housed in the container and configured with indicia to communicate a message. One or more secondary objects in communication with a weight are housed in the container. A combination of the weight and buoyancy characteristics of the secondary object(s) supports floating of the secondary object in the fluid.

A method, system, and article are provided for monitoring performance of hardware devices. Each hardware device is configured with an agent, and the server is configured with a coordinator. The agent collects device data at a first modifiable frequency and communicates the collected data to the coordinator at a second dynamically modifiable frequency. The collected data is periodically monitored and the first and second frequencies are modified subject to evaluation of the collected and monitored data.

Embodiments of the invention relate to modeling communities associated with groups of data items. Tools are provided to iteratively assign data items to communities and to update topic and participant distribution in the assigned communities. As the distributions are updated, the characteristics of the communities are updated. Each activity area is defined from the perspective of a single user. Participants in a community are connected to a user, but not necessarily to each other. The combination of formations of communities and the statistical aspect of evaluating characteristics of the communities provides a multi-facetted organization of connections between data items and associated participants.

A method and apparatus are provided to create a parent XSD document that separately identifies localized data and non-localized content definitions. A tool is employed to parse the localized content definitions from the non-localized content definitions. The parsing tool generates a child XSD document pertaining to the localized content definitions identified within the parent XSD document. One or more child XML documents are created to store data pertaining to the localized content definitions of the child XSD document. Localized content is isolated in a child XML document that is governed by a corresponding child XSD document, wherein the corresponding child XSD document is derived from the parent XSD document. Just as with any other XML document, the localized content in the isolated child XML document is supported by querying and validation by XML tools.
摘要:
Embodiments of the invention relate to profiling activity. Content is captured and keywords are identified in the captured content. In response to the keyword identification, rules associated with the keywords are identified. These rules are employed to identify and capture relevant content in real-time.
摘要:
Embodiments of the invention relate to dynamic power management of storage volumes and disk arrays in a storage subsystem to mitigate loss of performance resulting from the power management. The volumes and arrays are prioritized, and in real-time power is selectively reduced in response to both the prioritization and an energy savings goal. A feedback loop is provided to dynamically measure associated power gain based upon a lowering of power consumption, and device selection may be adjusted based upon received feedback.

Embodiments of the invention relate to data replication and block allocation in a file system to support write transactions. Regions in a cluster file system are defined to support a block allocation. Blocks in the defined regions are allocated to support the data replication. A pipeline manager is provided to schedule population of the blocks in the allocated region(s) based upon network characteristics.

A method and system are provided for splitting a live-range of a variable in frequently executed regions of program instructions. The live-range of a variable is split into multiple sub-ranges, each of which can be assigned to a different register or spilled into memory. The amount of spill code is reduced in frequently used regions of code by coalescing the live ranges based on profile information obtained after splitting the live ranges at every join and fork point in a control flow graph.
