Operating system for real-time hybrid environment
First Claim
1. A distributed data processing system comprisinga plurality of nodes comprising first and second nodes of distinct types having respective first and second operating systems, respectively,the plurality of nodes being adapted to maintain a distributed operating system, which operating system is adapted tosuperimpose a logical computational structure on the nodes, which logical structure is independent of the presence or absence of particular nodes, so that an application program running within the logical structure can continue to run while at least one of the nodes is being fundamentally altered;
- maintain a messaging protocol for communication between the nodes, which messaging protocol requires communication between nodes to be stateless.

Abstract
A distributed data processing system in a surface vehicle comprises sensors, user I/O, data processing and mass storage of geographical data. By means of a restricted library of system calls or primitives that can only be processed as unitary entities after deterministic transport control while keeping the transfer stateless, the distributed real-time operating system allows coexistent running of a plurality of processes that share localized processing power and/or a device, a sensor, I/O and/or file data.
