The task scheduling problem for Multiprocessor
System-on-Chips (MPSoC), which plays a vital role in performance, is an NP-hard
problem. Exploring the whole search space in order to find the optimal solution
is not time efficient, thus metaheuristics are mostly used to find a
near-optimal solution in a reasonable amount of time. We propose a novel metaheuristic
method for near-optimal scheduling that can provide performance guarantees for
multiple applications implemented on a shared platform. Applications are
represented as directed acyclic task graphs (DAG) and are executed on an MPSoC
platform with given communication costs. We introduce a novel multi-population
method inspired by both genetic and imperialist competitive algorithms. It is specialized
for the scheduling problem with the goal to improve the convergence policy and
selection pressure. The potential of the approach is demonstrated by
experiments using a Sobel filter, a SUSAN filter, RASTA-PLP and JPEG encoder as
real-world case studies.
