摘要
It is known that task scheduling problem of a complete kappa-ary intree with unit time tasks and general communication delays onto an unlimited number of processors is NP-complete. In this paper, we show that such a problem can be solved in linear time if we restrict communication delays within the range from (kappa - 1) to kappa unit times. We also show that naive scheduling is optimal if communication delays are constant and at most (kappa - 1) unit times.
