In this paper, we propose a reactive search-based algorithm for solving the problem of scheduling multiprocessor tasks on two dedicated processors. An instance of the problem is characterized by a set of tasks divided into three subsets and two processors, where some tasks can be executed either on one processor or two processors. The goal of the problem is to determine the scheduling of all tasks minimizing the execution of the last assigned task. The proposed reactive search starts with a starting greedy solution. Next, a series of local operators combined with a tabu list are introduced in order to intensify the search process. The method is also reinforced with a drop and rebuild operator that is applied for diversifying the search process. Finally, the performance of the proposed method is evaluated on a set of benchmark instances, where its provided results are compared to those achieved by a recent method available in the literature. Encouraging results have been reached.
