Abstract:

Above and beyond all the trends and developments in computer system design and implementation, are factors related to new applications domains.. We see an eclectic landscape that presents compelling new research, business and societal challenges – driven by the multi-disciplinary nature of societal problems – at the nexus of food, health, and energy. The next major innovations in computer science and engineering are likely to come from “intelligent” deployment of human-centric systems that must optimally interact with other man-made and natural systems with a focus on seamless availability of dynamic decision-making capabilities. Our need to measure, model, communicate, and manage our vast natural and social enterprise, requires a recognition that our physical world is complex and requires a level of adaptation and resilience that is unprecedented. New creative approaches are essential for handling the problems of scale and complexity envisioned in this future.

Applications, such as the smart power grid, medical electronics, robotic management and control, wireless sensor networks, cloud based systems – all driven by advanced data-analytics, have spawned a level of complexity where traditional fault-tolerance methods cannot form the backbone for resilient system design. Assumptions such as occurrence of a single fault in the system, independence of faults, or low-level of hardware and software interactions are easily foiled in these new settings. This means that a new set of fault models have to evolve and need to be studied carefully, either by significantly enhancing traditional techniques or by introducing new resiliency methods. Driven by studies of and observations from current technologies and systems, this talk will present research directions and challenges related to building resilient applications in several of the new domains.
