This invention describes a compilation method of extracting and implementing an accelerator control program from an application source code in a processor based system. The application source code comprises arrays and loops. The input application source code is sequential, with loop, branch and call control structures, while the generated output of this invention has parallel execution semantics. The compilation method comprises the step of performing loop nest analysis, transformations and backend processes. The step of loop nest analysis consists of dependence analysis and pointer analysis. Dependence analysis determines the conflicts between the various references to arrays in the loop, and pointer analysis determines if two pointer references in a loop are in conflict. Transformations convert the loops from their original sequential execution semantics to parallel execution semantics. The back-end process determines the parameters and memory map of the accelerator and the hardware dependent software.

A system and method predict the translation quality of a translated input document. The method includes receiving an input document pair composed of a plurality of sentence pairs, each sentence pair including a source sentence in a source language and a machine translation of the source language sentence to a target language sentence. For each of the sentence pairs, a representation of the sentence pair is generated, based on a set of features extracted for the sentence pair. Using a generative model, a representation of the input document pair is generated, based on the sentence pair representations. A translation quality of the translated input document is computed, based on the representation of the input document pair.

The virtual instant messaging system adds instant messaging and presence capability to devices and appliances which are not natively designed for instant messaging. The virtual instant messaging system performs the physical communication handling and semantic translation issues to allow legacy devices to operate within the instant messaging paradigm. Virtual devices, representing real devices or information sources, may be constructed, on the fly as needed, or on a more permanent or persistent basis. Multiple virtual devices may be combined to compose or synthesize a new virtual device, affording capabilities not found in the real world devices or information sources themselves.

User is given the new modeling capability, a Semantic Lasso, which allows grouping of the model elements, so they can be mapped or transformed to the high-level concepts of business ontology. Such grouping is done by drawing of the line contour around relevant to advertised high-level concept model elements on one of the OMG Unified Modeling Language (UML) class diagrams. In addition the user is given a capability to specify extension points of the high-level concepts and the projection of such extension points to the individual model. Another tooling capability, a Semantic Transformation Lens, allows dynamic graphical projection of the individual model fragments to the high-level concepts as those elements are being selected. Semantic Transformation Lens provides the mechanism of reasoning-based smart selection.

A software layer (filter driver) residing between software components or application programs running locally or on a client across a network and a persistent store of an operating system provides on-the-fly conversions of persistent information formats. The filter driver determines which format a program expects, and dynamically converts the information from its storage format to the format expected by the program. Conversion includes both data format conversion, and conversion of access semantics. Loadable conversion modules are provided for converting application specific formats due to the potential large number of such formats which can be encountered. The filter driver may change the format that information is stored in based on access history or other system requirements. The software components or application programs may be ignorant of the true storage format used by the system, and thus the filter driver can be used to give old versions of software access to information stored in newer formats.
