Abstract

In a data center, load balancing is used for resource scheduling to maximize the resource utilization of servers. However, since the requirement of completion time is different across different tasks, traditional load balance methods typically ignore such heterogeneity, leading to enormous decrease in the quality of service. This paper introduced a time-utility function(TUF) to express the utility according to the completion time of a task. With TUF, this paper studied how to maximize the total utility of all active tasks by resource allocation, which could be proved to be NP hard. It designed a scheduling algorithm to allocate resources properly for tasks. The main idea was to decompose the original problem into a number of isomorphic small-scale subproblems, and used the precedence relationship between tasks to decide which task to allocate resource first. The performance of this proposed algorithm could be proved to be very close to the optimal results by theoretical analysis. Experiments show that the overall utility generated by precedence relation scheduling algorithm is about 1.5x to 2x of that generated by FIFO fair scheduling mechanism. In addition, this algorithm outperforms the state of art 2DFQ by a significant margin of 17%.
