Abstract
Task scheduling is crucial for achieving high performance in parallel computing. Since task scheduling is NP-hard, the efficient assignment of tasks to compute resources remains an issue. Across the literature, several algorithms have been proposed to solve different scheduling problems. One such approach is Ant Colony Optimization (ACO) which has a potential to benefit from a parallel execution. In this article, we propose two new scheduling methods based on parallel ACO to solve the problem of scheduling independent tasks onto heterogeneous multicore platforms. The results of performance measuements demonstrate the improvements on the makespan by both parallel ACO variants.
