INDUSTRIAL EMBEDDED HPC APPLICATIONS

Industrial embedded HPC applications from different application domain s have many common requirements with respect to fault tolerance. The E FTOS framework provides a flexible and parametrisable set of tools fro m which the application developer can select to make the embedded appl ication more fault-tolerant This framework consists of a fault toleran ce backbone to which a set of tools can be hooked, These tools provide s generic, tailored or application-specific detection and recovery fun ctions. The backbone co-ordinates detection, diagnosis and recovery ac tions to bring the application back into a consistent state. The integ ration of this framework in the image processing module of a postal au tomation system, and in the sequence controller of a High Voltage Subs tation of an energy distribution network, ensures the industrial usefu lness and the flexibility of the approach, while the guideline of port ability allows efficient reuse of the framework.
