Purpose and goal
The particular purpose and goal of Chalmers research in the project was to improve the availability of systems at increased fault rates. In particular Chalmers goal was to design System components (microprocessors and networks) able to tolerate permanent faults, as well as to develop a runtime manager that would allow a system composed of such components to gracefully degrade its performance and functionality as more and more system parts fail.
Expected results and effects
Using the solutions designed by Chalmers: -future Chip multiprocessors can tolerate 3 times more permanent faults than conventional solutions. -Service-oriented Networks-on-Chip can tolerate 2-3 times more permanent faults compared to simple detouring of packets. -Using the proposed custom heuristics, a runtime manager can offer the efficiency of existing algorithms for adapting a system to dynamic changes at 10 times faster response times. Overall, the expected impact of Chalmers research on the project is to improve the availability of future mixed criticality systems.
Planned approach and implementation
Chalmers research on the design and implementation of highly available systems progressed according to the plan. Microprocessor and Networks-on-Chip design models were developed and evaluated and subsequently implemented to get accurate measurements. Runtime management heuristics were evaluated using realistic automotive use cases.
