Abstract: A computer-implemented system (90) is provided that supports a high degree of separation between processing elements. The computer-implemented system (90) comprises a plurality of cells (92) residing on the computer-implemented system, where each cell (92) includes a domain of execution (94) and at least one processing element (96); a separation specification (99) that governs communication between the processing elements (96); and a kernel (98) of an operating system that facilitates execution of the processing elements (96) and administers the communication between the processing elements (96) in accordance with the separation specification (99), such that one processing element (96) can influence the operation of another processing element (96) only as set forth by the separation specification (99). In particular, the separation specification provides memory allocation, remote procedure calls and exception handling mechanisms.

Abstract: A system is disclosed for formulating structure descriptions from data. In some embodiments, data arrives with an unknown format. The data may be ad hoc data that is considered semi-structured. Disclosed embodiments analyze chunks of the data to determine tokens. Tokens are analyzed to identify base types and compound types such as structs, unions, and arrays. Descriptions are generated and undergo scoring and rewriting for optimization. The generated descriptions may be fed to a data description language such as Processing Ad Hoc Data System (PADS) and compiled for processing the raw data. In some embodiments, the raw data is parsed, printed, or reformatted using the generated descriptions.

Abstract: An architecture model (10) provides a model of a data processing system. Pre-condition checks (51-52) and post-condition checks (71-72) are added to the architecture model (10) produce a reliability enhanced architecture model (50) to detect faults achieving a desired fault grade. Applying optimization techniques to the conditional checks of the reliability enhanced architecture model (50) reduces the complexity of implementing the model while maintaining or increasing the overall fault grade. The implementation of the reliability enhanced architecture model (50) when hosted on a separation architecture ensures the fault grade specified for the model.
