In general, in one aspect, the invention provides a modular application collaborator for providing inter-operability between applications including a plurality of connectors for communicating with a like plurality of applications and an interchange server. The interchange server includes an application collaboration module and service module. The service module transfers messages between connectors and the application collaboration module. The application collaboration defines the inter-operability between two or more applications. The interchange server service module includes a transaction service and an error service. Transactions are executed in the application collaboration module and the transaction service records each action and a compensating action for undoing an associated action. An error service monitors for errors in the interchange server, and, upon detection of an error, stops the execution of a transaction and initiates the execution of any required compensating actions to undo the interrupted transaction. The compensating transactions may be executed at the connectors and are not required to be overseen by the interchange server.

A distributed gateway for controlling computer network data traffic dynamically reconfigures traffic assignments among multiple gateway machines for increased network availability. If one of the distributed gateway machines becomes unavailable, traffic assignments are moved among the multiple machines such that network availability is substantially unchanged. The machines of the distributed gateway form a cluster and communicate with each other using a Group Membership protocol word such that automatic, dynamic traffic assignment reconfiguration occurs in response to machines being added and deleted from the cluster, with no loss in functionality for the gateway overall, in a process that is transparent to network users, thereby providing a distributed gateway functionality that is scalable. Operation of the distributed gateway remains consistent as machines are added and deleted from the cluster. A scalable, distributed, highly available, load balancing network gateway is thereby provided, having multiple machines that function as a front server layer between the network and a back-end server layer having multiple machines functioning as Web file servers, FTP servers, or other application servers. The front layer machines comprise a server cluster that performs fail-over and dynamic load balancing for both server layers.

An intercom system is provided having a plurality of intercom stations coupled to a digital network, each station transmitting intercom data onto a channel of the network. Each station receives intercom data from each other station and selects channels to be amplified and output to a speaker. Each station may listen to and talk to any other station or any selected group of stations. Processing of signals from the network is performed in each station, thereby eliminating the need for a centralized mixing and switching device. Stations may be added merely by connecting them to the network. The intercom system may be configured in a non-blocking mode or in a blocking mode.

A system and method for providing an Application Programming Interface (API) that allows users to write complex graphics and visualization applications with little knowledge of how to parallelize or distribute the application across a graphics cluster. The interface enables users to develop an application program using a common programming paradigm (e.g., scene graph) in a manner that accommodates handling parallel rendering tasks and rendering environments. The visualization applications written by developers take better advantage of the aggregate resources of a cluster. The programming model provided by APT function calls handles scene-graph(s) data in a manner such that the scene and data management are decoupled from the rendering, compositing, and display. As a result, the system and method is not beholden to one particular graphics rendering API (e.g. OpenGL, Direct X, etc.) and provides the ability to switch between these APIs even during runtime.

A computer-implemented method and a distributed file system in a distributed data network in which file metadata related to data files is distributed. A unique and non-reusable mode number is assigned to each data file that belongs to the data files and a directory of that data file. A key-value store built up in rows is created for the distributed file metadata. Each of the rows has a composite row key and a row value (key-value pair) where the composite row key for each data file includes the mode number and a name of the data file. When present in the directory, the data file is treated differently depending on size. For data files below the maximum file size the entire file or portion thereof is encoded in the corresponding row value of the key-value pair. Data files above maximum file size are stored in large-scale storage.

Building binary packages for software products, particularly large-scale software products, is a highly computation intensive process. Thus, it is desirable to distribute the workload over a large number of computing nodes so as to have the build process complete in an optimal period of time. One environment providing compute resources that can be utilized for a highly available and dynamically scalable distributed build process is an elastic compute cloud. In such an environment, virtual machines can be instantiated and destroyed as the resource requirements of the build process dictate. This has the advantage that dedicated hardware is unneeded, and excess capacity on the hardware employed can be employed for other computation tasks when the build process is idle. Presented herein are systems, methods and computer storage media for distributing a highly available and scalable build service, suitable for use in an elastic compute environment or other distributed environment.

A scalable power distribution system for a data center and methods for scaling a power distribution system are described. The scalable power distribution system includes a transformer that is connected to a load at its output. The input of the transformer is connected to two isolation switches. A source is connected to one switch at all times, and the source can be switched without affecting power to the load by synchronizing the two sources at the transformer before switching sources. The load is not de-energized at any time during the transfer process.

A fault tolerant system for a highly scalable distributed processing system in which fault tolerant groups (hereafter referred to as “FT groups”) are formed based on the functionalities of applications. A given FT group includes instances of the same applications and also different applications that perform the same function. The instances within the FT group are ranked as a primary and mirrors, which descend in rank. When the primary instance in the FT group crashes, that is, fails or becomes otherwise unavailable, the system utilizes the next ranking available (running) instance in the FT group as the primary instance. The change over to the next ranking mirror application is performed quickly and without loss of functionality through an exchange of “FT messages” under the control of a central monitoring and change-over control sub-system.

A structured query language interface provides access to information stored in a social network system. The interface allows third party systems to treat the information stored in the social networking system as a distributed database.

The information provided in response to a structured query may be subject to multiple levels of access control including, business logic rules applicable to users of the social networking system or privacy limitations set by individual users. The social networking system uses a scripting language to extract the information and apply business logic rules to the data.
