We propose an off-line scheduling heuristics which, from a given software application graph and a given multiprocessor architecture (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.
