摘要:
A system, method and computer program product for seismic imaging implements a seismic modeling algorithm utilizing Forward Wave Inversion technique for revising Reverse Time Migration models used for sub-surface modeling. The technique requires large communication bandwidth and low latency to convert a parallel problem into one solved using massive domain partitioning. The partitioning of a velocity model into processing blocks allows each sub-problem to fit in a local cache, increasing locality and bandwidth and reducing latency. The RTM seismic data processing utilizes data that includes combined shot data, i.e., shot data selected from amongst a plurality of shots that are combined at like spatial points of the volume. An iterative approach is applied such that the correction term RTM generates at each iteration in the iterative approach is used for refining the model, and the updated model is used for generating a further refined RTM model.

An end-to-end record, request, response token-based protocol is used to facilitate processing of client jobs. This allows the client to forward analytical tasks of a job directly to an analytics cluster and to record an indication of such at a server. The accelerators of the cluster to perform the tasks are specified in a token provided by the server to the client.

Request processing within a computing environment is facilitated. Request processing and analytics processing for the request are performed substantially concurrently in order to improve efficiency of request execution. The analytics processing is at least commenced, and may complete, prior to receiving an indication of success or failure of the request processing. If request processing fails, analytics processing ceases, if not already complete, and results of the analytic processing are not used.

Stream processing is facilitated by distributing responsibility for processing the stream to multiple components of a computing environment. A programmable unit receives one or more streams and determines the operations to be performed for the one or more streams and which components of the computing environment are to perform those operations. It forwards data relating to the one or more streams to one or more components of the computing environment for processing and/or information purposes.
摘要:
A system, method and computer program product for seismic imaging implements a seismic imaging algorithm utilizing Reverse Time Migration technique requiring large communication bandwidth and low latency to convert a parallel problem into one solved using massive domain partitioning. Several aspects of the imaging problem are addressed, including very regular and local communication patterns, balanced compute and communication requirements, scratch data handling and multiple-pass approaches. The partitioning of the velocity model into processing blocks allows each sub-problem to fit in a local cache, increasing locality and bandwidth and reducing latency. The RTM seismic data processing utilizes data that includes combined shot data, i.e., shot data selected from amongst a plurality of shots that are combined at like spatial points of the volume.

摘要:
A system and method for delivering electronic messages automatically to transaction cards. The transaction cards are capable of rendering electronic messages from a server using a transaction activated connection. This system can be used to automatically deliver user specific information such as calendar, reminder, or e-mail information to a person scanning their card in, for example, a building where scanning a badge is required to enter the building. Alternatively, the system can be used to automatically deliver public information to a user such as advertisements to a render-capable transaction card which includes, for example, a calling card, a credit card, or a public transportation access card.
摘要:
A system, method and program product uses tags as markers for incorporating local content in a communications stream, e.g., TV broadcast, cable transmission. A transmitter generates a communication stream including program content for transmission to a receiver. The transmitter includes an authoring tool for generating two types of tags for incorporation into the program content. The receiver captures the program content and stores the tags in tables. One type of tag initiates local action in the program content in the communication stream. A second type of tag is capable of modifying the first type of tag in the tables. When the time for a local action according to a first type of tag is detected, the program content is interrupted by splicing or inserting the local content.

An improved method and apparatus are disclosed for selectively inserting interactive content into a live TV or recorded broadcasting presentation and tracking the usage of the inserted content by end user viewers of the presentation. The method and apparatus enable operators to watch the live audiovisual programming feed, view and navigate product lists from e-commerce servers, control the insertion of interactive content into the audiovisual programming, monitor the content insertion status, and track the usage by client viewers of the inserted content in real time. It is especially useful for interactive e-commerce applications.
