Abstract
We consider the problem of online scheduling a set of equal-processing-time tasks with precedence constraints so as to minimize the makespan. For arbitrary precedence constraints, it is known that any list scheduling algorithm has a competitive ratio of 2 - 1 / m, where m is the number of machines. We show that for intree precedence constraints, Hu's algorithm yields an asymptotic competitive ratio of 3/2. © 2008 Elsevier B.V. All rights reserved.
