Abstract:

Divisible-load scheduling has become an increasingly hot subject in the research on information technologies in recent years. Most existing divisible-load scheduling models assume that all processors are idle at the beginning of workload assignment. In fact, many processors may still in the busy state when a new workload arrives. Processors may have different waiting times from the busy state to the idle, that is, processors have different release times. This paper proposes a new release time aware divisible-load scheduling model with hybrid time constraints and designs an effective global optimization genetic algorithm to solve it. Finally, experimental results show the effectiveness of the proposed model and the efficiency of the proposed algorithm.

Key words: divisible-load scheduling, release time, hybrid time constraints, genetic algorithm
