Abstract

Codelet dataflow model has significant effects on gaining high performance of computing large-scale parallel tasks, but the model currently lacks scheduling policy in heterogeneous multi-core environment. Regarding to this issue, this paper proposed a Codelet task scheduling strategy by fusing ant colony algorithm with a heuristic approach in heterogeneous multicore environment. It had both advantages of the heuristic algorithm and ant colony algorithm, and it overcame both defects of the heuristic algorithm that could not derive an optimal solution and the defects of the ant colony algorithm that was lack of the initial information. The experimental result shows, the smart ant colony scheduling policy is much more efficient than the native dynamic and static scheduling policies in the runtime system implementation of the Codelet model.
