An efficient list scheduling algorithm with task duplication for ...

WebEfficient scheduling algorithms have been a leading research topic for heterogeneous computing systems. Although duplication-based scheduling algorithms can significantly reduce the total completion time, they are generally accompanied by an exorbitant time complexity. In this paper, we propose a new task duplication-based heuristic scheduling … List scheduling is a greedy algorithm for Identical-machines scheduling. The input to this algorithm is a list of jobs that should be executed on a set of m machines. The list is ordered in a fixed order, which can be determined e.g. by the priority of executing the jobs, or by their order of arrival. The … Meer weergeven Suppose there are five jobs with processing-times {4,5,6,7,8}, and m=2 processors. Then, the resulting schedule is {4,6,8}, {5,7}, and the makespan is max(18,12)=18; if m=3, then the resulting schedule is … Meer weergeven Instead of using an arbitrary order, one can pre-order the jobs in order to attain better guarantees. Some known list scheduling strategies are: • Highest … Meer weergeven The algorithm runs in time $${\displaystyle O(n)}$$, where n is the number of jobs. The algorithm always returns a partition of the jobs whose makespan is at most $${\displaystyle 2-1/m}$$ times the optimal makespan. This is due to the fact that both the length of … Meer weergeven The list scheduling algorithm has several anomalies.
