Local Decisions and Triggering Mechanisms for Adaptive Fault-TolerancePhillip Stanley-Marbell and Diana Marculescu.In Proceedings of the conference on Design, Automation and Test in Europe, DATE '04, February 2004.
This paper introduces and analyzes the role of local decision
policies in a DFTM environment, and presents a pre-
cise formulation for when it is beneficial to activate a given
DFTM algorithm with respect to metrics that combine performance,
reliability, power consumption and battery life.
In particular, local decision algorithms are described in
the context of an imaging array application running on a
network of resource-constrained processing elements. It is
demonstrated that DFTM algorithms, in conjunction with
appropriately chosen activation times, increase the mean
computation before battery failure for a single battery, by a
factor between 1.1 to 5.8, for the application investigated.
