Mechanisms and techniques provide a system to evaluate operational integrity of a data processing system such as an area augmentation system by obtaining at least one set of distribution data related to information processed by the data processing system. The set(s) of distribution data can include corrections information and integrity bounds information related to the corrections information. The system applies a moment generating function to the set of distribution data to produce a moment bounded distribution data result and compares the moment bounded distribution data result to an integrity limit to determine if the data processing system operates within an acceptable integrity threshold. The system can be used in real-time or non-real time with sets of distribution data that are non-Gaussian, non-symmetric and/or non-unimodal.
A system, method and computer program product for dynamically debugging a multi-node network comprising an infrastructure including a plurality of devices, each device adapted for communicating messages between nodes which may include information for synchronizing a timing clock provided in each node. The apparatus comprises a plurality of probe links interconnecting each node with a probe device that monitors data included in each message communicated by a node. Each probe device processes data from each message to determine existence of a trigger condition at a node and, in response to detecting a trigger condition, generates a specialized message for receipt by all nodes in the network. Each node responds to the specialized message by halting operation at the node and recording data useful for debugging purposes. In this manner, debug information is collected at each node at the time of a first error detection and collected dynamically at execution time without manual intervention.
