Abstract: A method and article for efficiently accessing resources in a multiprocessor computer system. Multiple resources are grouped into nodes and system resource descriptors are maintained as data structures. The method incorporates traversing one or more of the data structure to efficiently allocate resources within a grouping of nodes. Each node in the system is assigned a node identifying number. This number identifies a node location within a multiprocessor and is used to determine latency between nodes. Accordingly, storing the system architecture information in a data structure format provides for an efficient method of accessing system resources and determining latency for specific processes and access patterns.

Abstract: Multiple two dimensional graphs are combined into a single two dimensional graph wherein correlations between dimensions are maintained. Dimensions in the graph can be superimposed on each other and displayed while maintaining the two dimensional format. This enables the two dimensional graph to be converted to three or more dimensions while maintaining the format and presentation in a two dimensional visual display.

Abstract: A method and computer system for efficiently handling high contention locking in a multiprocessor computer system. At least some of the processors in the system are organized into a hierarchy, and process an interruptible lock in response to the hierarchy. The method utilizes two alternative methods of acquiring the lock, including a conditional lock acquisition primitive and an unconditional lock acquisition primitive, and an unconditional lock release primitive for releasing the lock from a particular processor. To prevent races between processors requesting a lock acquisition and a processor releasing the lock, a release flag is utilized. Furthermore, in order to ensure that the a processor utilizing the unconditional lock acquisition primitive is granted the lock, a handoff flag is utilized.

Abstract: A method, apparatus, and article of manufacture to dynamically address and resolve an improper shut-down of an application. Internal state data of the application is stored in persistent memory. New internal state data is dynamically created and authenticated following an improper shut-down of the application. Responsive to the authentication, the application is re-started with the authenticated new internal state data, without being subject to an immediate improper shut-down.

Abstract: A method and apparatus for restricting access of an application to computer hardware. The apparatus includes both an authentication module and a validation module. The authentication module is within the trusted firmware layer. The purpose of the authentication module is to verify a cryptographic key presented by an application.

The camera turret comprised of two hemispheres has a full 360 degree freedom of pan rotation and up to 140 degree of tilt rotation. The mount includes a tilt assembly embedded within the turret and a pan assembly external to the turret. The tilt assembly in communication with a tilt feedback device provides a tilt movement to the turret. The pan portion in communication with a pan feedback device provides a pan movement to the turret. The mount is configured to be mounted on a land based vehicle, a water based vehicle, or an aerial vehicle.

Abstract: A computer storage library is configured to include a plurality of storage media, with individual storage media housed in respective individual storage slots. Each of the storage media slots may communicate with a storage controller, which in turn may communicate with a host through a network connection. A delivery device is provided for enabling a connection between individual storage slots and a host via the controller on demand. The delivery device enables the storage media to remain stationary during the connection process.

Abstract: A method and system for localizing and resolving a fault in a cluster environment. The cluster is configured with at least one multi-homed node, and at least one gateway for each network interface. Heartbeat messages are sent between peer nodes and the gateway in predefined periodic intervals. In the event of loss of a heartbeat message by any node or gateway, an ICMP echo is issued to each node and gateway in the cluster for each network interface. If neither a node loss not a network loss is validated in response to the ICMP echo, an application level ping is issued to determine if the fault associated with the absence of the heartbeat message is a transient error condition or an application software fault.

Abstract: A method and apparatus are provided to support autonomic computing for system configuration. Common base events (CBEs) are generated and, based upon system configuration, are employed to monitor system resources and to resolve system configuration conflicts prior to an error. A symptom database stores a set of rules for the configuration information. The configurations CBEs for the system configuration are compared with the symptom rules, and any discrepancies between the two elements are communicated to a user prior to an occurrence of an error in the system. Accordingly, an autonomic computer system is provided to support system configuration data.

Abstract: The instantaneous flow of an injector for gaseous fuels is calculated by measuring the pressure and temperature of a test gas injected inside a measuring chamber connected to the external environment in a continuous manner through a given outlet section and using a calculation formula, in which the instantaneous flow of the injector is a function of on the measured pressure, of a first factor as a function of a volume of the measuring chamber and the measured temperature, and of a second factor as a function of the measured temperature and the outlet section.

Abstract: Disclosed is an application program which can directly access a transmit buffer of a serial port. Data written into the transmit buffer by the application program is transferred into a receive buffer of the serial port via a switching element. The computer BIOS is enabled to directly access the receive buffer and therefore read the data written by the application program. The state of the switching element may be controlled by the application program to selectively allow data transfer from the transmit buffer to the receive buffer. A jumper plug may be used to create a short circuit between the transmit buffer and the receive buffer instead of closing the switching element.

Abstract: Method and framework for identifying optimal allocations of computing resources in a complex, distributed data processing environment. A plurality of server models are established, with each server model including one or more server nodes and each server node having an associated set of capacity attributes. Similarly, a plurality of service models are established, each service model including one or more service nodes and each service node having an associated set of demand attributes. The server models are defined with a layered relationship as are the service models. A node that is part of a model in one layer corresponds to a model in the next-lower layer. The invention generates optimized mappings of service nodes that are described in user-selected service models to server nodes that are described in user-selected server models, as a function of the associated sets of demand and capacity attributes.

Abstract: When a mobile node suffers an abrupt shut down while operating in a foreign network and recovers in its home network, the present invention enables the mobile node to reestablish communication capability, without time delay, with the nodes that had established one or more communication sessions with the mobile node prior to the abrupt shut down. The mobile node of the present invention includes an update module that determines whether additional information needs to be sent to the nodes in communication with the mobile node prior to the mobile node suffering an abrupt shut down. Based on that determination, the update module may provide additional information to such nodes.
