Paralleling processing system and method. When clusters are formed based on strongly connected components, a single cluster (fat cluster) having at least a predetermined number of blocks, or an expected processing time exceeding a predetermined threshold, is formed. The fat cluster is subjected to an unrolling process to make multiple copies of the processing of the fat cluster and to assign the copies to individual processors. Processing of the fat cluster is executed by the multiple processor devices in a pipelined manner. If a fat cluster to be iteratively executed cannot be executed in the pipelined manner because a processing result of an nth iteration of the fat cluster depends on a processing result of a preceding iteration of the fat cluster an input value needed for execution of the fat cluster is generated based on a certain prediction, and the fat cluster is speculatively executed.

Upon reception, by the destination network server, of the datagram sent by the network load balancing system, the MAC address in the destination MAC address field of the datagram MAC header is identified as being the MAC address of the selected destination network server, and the IP datagram is processed if the identified cluster public IP address in the destination IP address field of the datagram IP header, is defined as a non-advertising alias in the interface table of the destination network server.

A method and system for election of a cluster leader in a storage area network is provided Each node in a grouping of storage area network nodes communicates with each of the nodes on a periodic basis to determine if any of the nodes have failed (42). In the event of a cluster fault, each node may request a position of cluster leader. A pruning protocol (60) is invoked to ensure efficient convergence of a single cluster leader candidate to favor a majority grouping leader candidate to become the new cluster leader. In the event the leader candidate from the majority grouping has failed to become the new cluster leader, a minority grouping leader candidate can become the cluster leader. Following the pruning protocol, a voting protocol (100) is invoked followed by lock of the quorum disk (138) by the elected cluster leader candidate.

Ocean bottom seismic cables are subject to rolling motions due to seismic wave fields and current action which cause poor receiver ground-coupling and signal distortion, particularly along the cross-line and vertical axes. Two multi-axial receivers are mounted on opposite sides of the cable in a single cluster. When the cable rolls, the axial response of one receiver of the cluster cancels the axial response of the other receiver of that cluster.

A group of network devices, such as Ethernet switches, are logically configured as a single cluster, with one commander device and one or more expansion devices. Each device in the cluster contains an embedded HTML server that facilitates configuration and management of the network device via a management station running a Web browser. Each device in the cluster is identified by a unique Universal Resource Locator (“URL”). However, only the cluster commander is required to have an IP address. The cluster commander redirects and translates configuration and management requests from the Web browser on the management station so that requests are processed by the appropriate device in the cluster. The exchange of information between the Web browser on the management station and the devices in a cluster is accomplished via redirection of HTTP GET and POST methods. This provides a consistent, device-independent interface between the device and the Web browser on the management station.

A hybrid quorum / consensus and primary-backup fault-tolerance model in an object-based distributed data storage system. When a primary manager fails, a hierarchy of network entities is established in which a group of realm managers first authorizes a failure-handling event through quorum / consensus and a backup manager (for the failing primary manager) then executes the decision of the quorum of realm managers. The realm managers, operating by consensus, determine whether (a) the primary manager can indeed be asserted to be down, and (b) whether there is a quorum of realm managers in agreement on this decision. If both are true, a master realm manager instructs the backup manager to proceed to execute the necessary steps to become the primary manager and function as the primary until the original primary manager is brought back into service. The hybrid fault-tolerance approach handles both single unit failures and network partitions in a unified way, without creating a single cluster out of the fault domain.

A sequence of video images is generated of a pavement area of an airport which contains one or more objects. A processor accesses a background model of the pavement area and determines in a current image a single cluster of foreground pixels that is not part of the background model and assigns a first value to each foreground pixel in the cluster to create a foreground mask. The background model is updated by learning new conditions. A convex hull is generated from the foreground mask.

A ratio higher than a threshold value indicates an object not being an airplane and an alert is displayed on a computer display. Images may be thermal images. A surveillance system based on the calculated ratio is disclosed.

A split deployment model is enabled for a telecommunication service access gateway. The services of the gateway are segregated into a set of core services that provide container-based functionality and a set of exposure services that enable network integration and translation of protocols. The core services are executed as part of the application server, while the exposure services are deployed in separate archive files. This isolation of services allows single or groups of services to be independently upgraded, patched or removed and reduces the impact of one service on others. Furthermore, the services can scale independently, allowing additional hardware resources to be added to a particular service. Multiple versions of a single service can also be deployed in a single cluster or server.
