Abstract: A data processing system with a dataset multiplexer that enables applications to be written to specify access to datasets as operations on logical datasets. During execution of an application by the data processing system, operations that access a dataset are implemented by accessing an entry in a dataset catalog for the logical dataset. That entry includes information to access the physical data source storing the logical dataset, including conversion of data from the format of the physical data source to the format of the logical dataset. An entry in the catalog may be created based on registration of a data source with the dataset multiplexer and may be updated automatically based on changes in storage of the dataset. This maintenance of the catalog may be partially or totally automated such that the system automatically adjusts to any changes in storage of the dataset without need for modification of any application.

At least one sensor is coupled to the analyzer and configured to generate at least one signal related to gas being supplied to the gas appliance. A smart device communicates with the analyzer, wherein the smart device has a user interface and is configured to monitor, store and display data. The smart device can present any or all of a plurality of parameters such as the flow of gas, a capacity of the flow of gas, a temperature, a pressure of the gas and the like to a user based on signals from sensors.

Abstract: A data processing system with a dataset multiplexer that enables applications to be written to specify access to datasets as operations on logical datasets. During execution of an application by the data processing system, the physical dataset used for performing data access operations may be selected based on current context. Current context may be specified based on values of system parameters and/or user specified values. The physical dataset accessed may be identified by selecting a record from multiple records in a dataset catalog associated with the logical dataset. Each record includes information to access a physical dataset associated with the selected record and context information to indicate the context in which the specific physical dataset is to be selected.

According to one embodiment, the overlay network may comprise at least one virtual network switch (VNS), wherein each VNS is installed within a corresponding first processing endpoint which is logically above a network of virtual machines. And, the VNS may be configured to intercept data packets transmitted on a network layer logically below the network of virtual machines.

Abstract: In a processing system, an identifier for a current version of code for an application is published in a message to a shared event stream. Any instances of the application within the processing system may update to the current version before processing other messages having sequence numbers after the message containing the identifier. In this manner, multiple instances of the application may be periodically updated to maintain global consistency of the application and the shared event stream.

Abstract: Embodiments of the present invention provide a novel system and method for TCP-to-multicast (T2M) communications. The T2M techniques may allow a client to make a single TCP connection that then fans out into communications with multiple back-end resources. Such one-to-many communications may be invisible to the client but can achieve many practical benefits.

Abstract: Communication techniques are disclosed for a distributed computing system. The technique may be applied to an inline clearing and settlement messaging protocol whereby a matching engine may issue a transaction request (or settlement request) upon matching a proposed trade, identifying the parties and assets for the trade. A message gateway may validate and transmit the transaction request to a sequencer which sequences the transaction request into a time-accurate event stream so that transaction requests are distributed to relevant parties in chronological order. Each party may respond to the transaction request by simply checking its account to confirm availability of the relevant asset for the proposed trade and issuing a clearance response. The clearance responses form the basis for a transaction response that the message gateway sends to the matching engine to indicate success or failure of the inline clearing and settlement.
