An integrated QoS-aware job dispatching policy is proposed, which correlates priorities of incoming jobs used for job selecting at the local scheduler of the grid node with the job dispatching policies at the global scheduler for computational grids. The stochastic high-level Petri net （SHLPN） model of a two-level hierarchy computational grid architecture is presented, and a model refinement is made to reduce the complexity of the model solution. A performance analysis technique based on the SHLPN is proposed to investigate the QoS-aware job scheduling policy. Numerical results show that the QoS-aware job dispatching policy outperforms the QoS-unaware job dispatching policy in balancing the high-priority jobs, and thus enables priority-based QoS.展开更多

Accordingly, a structural model is developed to delineate the interactions among these constructs and explore the mediating effect of job satisfaction on the relationship between job involvement and organizational commitment. A questionnaire-based survey was designed to test the aforementioned model based on a dataset of 315 employees working in twelve out of twenty six banks operating in the capital city of Jordan, Amman. The model and posited hypotheses were tested using structural equation modelling analysis. The results indicated that job involvement positively and significantly affects job satisfaction and organizational commitment. Additionally, job satisfaction proved to be positively related to organizational commitment. Furthermore, job satisfaction positively and significantly partially mediated the relationship between job involvement and organizational commitment.展开更多
