Abstract: In a multicast publisher-subscriber environment, a configurator machine manages a consumer pool of multiple receiver machines. The consumer pool is dedicated to a topic. Each receiver machine has a unique consumer address within the consumer pool allocated by the configurator machine. The configurator machine receives registration data from a receiver machine to be added to the consumer pool and provides a consumer address to the receiver machine. The receiver machine transmits a multicast communication to advertise its availability to receive messages on the topic. The multicast communication includes the consumer address. A transmitter machine may publish a message on the topic. The message may be a multicast communication directed to any receiver machine in to the consumer pool, or the message may be a point-to-point communication directed to the receiver machine with the consumer address.

Resource allocation queries are submitted to any level node within the hierarchy and forwarded to the proper computing system for processing.

Abstract: A method of providing three dimensional (3D) information is disclosed in which a master recruits a local slave to provide contemporaneous images. The images are collected and 3D information extracted therefrom. The 3D information or various images may be transmitted to a remote device and is employed to provide a substitute background that replaces the background of the original image. Either the new image is displayed on one or both devices. The images can be collected and the 3D information extracted at either of the master or slave or at a separate device. To recruit the slave, the master broadcasts a query to all local devices, determines the available devices and their characteristics, automatically or manually selects a particular device, requests authorization from the selected device, and pairs with the selected device when authorization is received. Devices of the same or different types may be paired.

Abstract: Resources are partitioned via a virtual partitioning system to distribute the resources over a plurality of resource servers. A virtual partition table can be kept at each of a set of resource managers handling requests for resources in tandem. When a resource is requested, a virtual partition value is calculated algorithmically, and the value is mapped to a resource component via the virtual partition table. The resource component encapsulates information indicating on which of the resource servers the resource resides and can provide a component for performing operations on the resource even though the requester does not have information about where the resource resides. The resources can be repartitioned by modifying the virtual partition table, thus allowing the addition of additional resource servers to the system while the resources remain available. Additional resource types can be added without reengineering the system.

Abstract: Various embodiments described herein include one or more of systems, methods, firmware, and software to synchronize system information between processors during system boot in a links-based multi-processor system.

These and other embodiments are described in greater detail below.

Abstract: Hitherto synchronization of a number of devices has involved a large number of comparison steps between actual data or changes in data. Such comparison has potentially involved extensive redundant comparison steps. Another problem with existing synchronization methods is that such synchronization has been effected based upon the systems clocks defined by the devices. Those system clocks can be modified either intentionally or malevolently with disastrous consequences for subsequent synchronization of the devices. Accordingly, the present invention relates to a method of synchronization between three or more devices, the method involves: storing an indication of the device or devices involved in each synchronization event; storing data changes received during a current synchronization event together with the device submitting those changes; and applying the data changes subsequent to the stored synchronization event for the or each device.

Abstract: A method of controlling concurrent users of a distributed resource on a network is disclosed. In one aspect, there are one or more local lock managers executing on corresponding hosts and cooperating as a distributed lock manager. The resource is limited to a maximum number of concurrent users. A user identification for each user is associated with one host. In response to a request associated with a particular user associated with a first host, a lock is requested from a first local lock manager process executing on the first host. A related method of handling a request for a count-limited resource includes receiving a request from a client process for the computer resource. If it is determined that the request exceeds a maximum count for the resource, then it is determined whether a current time is within a retry time period of the client's first request.

Abstract: A system, method, and program product are provided that identifies a remote stored procedure stored in a remote database management system, and automatically generates a local stored procedure stored in a local database management system. To automatically generate the local stored procedure, local and remote metadata are gathered corresponding, respectively, to a local database management system and a remote database management system. The remote metadata is used to create a call statement to the remote stored procedure. The created invocation method maps input values, input to the local stored procedure, to input parameters of the remote stored procedure. Results in the local stored procedure are set by mapping the data returned from the remote stored procedure to the corresponding return values (e.g., parameters and result sets) in the local stored procedure values.

Abstract: A method of grouping nodes within a distributed network is provided. The example method includes performing a leader node self determination operation by which each node within the distributed network determines whether to become a leader node or a non-leader node, each leader node being the leader of a group including at least one node.

First received requests are accepted, at each non-leader node, such that accepting non-leader nodes transition from a non-leader node to a dependent node dependent upon the requesting leader node. A next set of requests are sent, from each remaining non-leader node, requesting to join the group associated with at least one leader node. A determination is made, at each requested leader node, as to whether to accept the non-leader node into the group associated with the requested leader node.

The supervisor keys are configured so as to prevent a given supervisor from partitioning resources not allocated to the client node associated therewith. Following the partitioning, communication packets are issued from the one or more applications to a resource provider node without inspection by the corresponding supervisor.
