Abstract: Multiprocessor system plays a key role in high performance computing.In order to improve the parallelism of the system,we proposed a new multiprocessor task scheduling algorithm,which is based on Cuckoo search(CS) algorithm.The algorithm takes the latest completion time of all tasks as the goal,and encodes based on task priority method to make continuous CS algorithm suitable for discrete task scheduling problem probably.The experimental results show that CS algorithm not only can obtain shortest task completion time,but also has the fastest solving speed.Its computation time is 60% lower than the widely used genetic algorithm and particle swarm optimization algorithm.
