Abstract
Three basic organizations have been proposed to construct the task queues for a shared memory multiprocessor system: centralized, distributed, and hierarchical structures. The centralized structure is not suitable for massively parallel systems since the centralized queue is a bottleneck. The distributed structure, on the other hand, will end up with load imbalancing due to the random execution time of tasks. The hierarchical structure tends to combine the advantages of the previous two structures and reduces the impact of bottleneck and load imbalancing. However, we found out that the load imbalancing still exists in the hierarchical structure. It also affects system performance, in particular, when the workload becomes heavier. We further identified the cause of this problem. We propose the use of a forest structure to provide load balancing and contention minimization.
