| Abstract: | Computational grids have become an appealing research area as they solve compute-intensive problems within the scientific community and in industry. A Grid computational power is aggregated from a huge set of distributed heterogeneous workers; hence, it is becoming a mainstream technology for large-scale distributed resource sharing and system integration. Unfortunately, current grid schedulers suffer from the haste problem, which is the schedule inability to successfully allocate all input tasks. Accordingly, some tasks fail to complete execution as they are allocated to unsuitable workers. Others may not start execution as suitable workers are previously allocated to other peers. This paper is the first to introduce the scheduling haste problem. It also presents a reliable grid scheduler. The proposed scheduler selects the most suitable worker to execute an input grid task using a fuzzy inference system. Hence, it minimizes the turnaround time for a set of grid tasks. Moreover, our scheduler is a system-oriented one as it avoids the scheduling haste problem. Experimental results have shown that the proposed scheduler outperforms traditional grid schedulers as it introduces a better scheduling efficiency. [ABSTRACT FROM AUTHOR] |
