A Generalized Task Allocation Framework for Dependable Real-Time Systems
Hüseyin Aysan, Radu Dobrin, Sasikumar Punnekkat · 2007
In this paper, we present a general framework which allowsthe designer to specify a wide range of criteria for allocation.Major factors considered as part of our frameworkare mixed criticalities of tasks, schedulability, power consumption,fault-tolerance, and dependability requirementsin addition to typical functional aspects such as memoryconstraints. This being a global optimization problem, weare forced to use meta-heuristic algorithms, and we wereable to represent these requirements in a very intuitive mannerby the usage of energy functions in simulated annealing.We envision the proposed methodology as a quite simple,scalable, as well as computationally effective solutioncovering a wide range of system architectures and solutionspaces.
