Tradeoff exploration between reliability, power consumption, and execution time

International audienceWe propose an off-line scheduling heuristics which, from a given software application graph and a given multiprocessor architec- ture (homogeneous and fully connected), produces a static multiprocessor schedule that optimizes three criteria: its length (crucial for real-time systems), its reliability (crucial for dependable systems), and its power consumption (crucial for autonomous systems). Our tricriteria scheduling heuristics, TSH, uses the active replication of the operations and the data-dependencies to increase the reliability, and uses dynamic voltage and frequency scaling to lower the power consumption
