Abstract: Abstract In this paper, we consider the semi-online hierarchical scheduling for load balancing on two identical machines. In the problem, the jobs are available online over list and the objective is to minimize the $$l_p$$ l p -norm of the two machines’ loads. Two semi-online versions are investigated: the buffer version and the rearrangement version. We design a unified optimal semi-online algorithm for both models.
