It is a vital necessity of a heterogeneous environment to schedule the resources efficiently among applications to optimize the execution time to provide well-regulated services to the users. The system is said to be effective only if it supplies the resources on time and assures smooth task execution. This paper introduces a dynamic task scheduling with advance reservation (DTSAR) of resources to optimize turnaround time (TAT). A task will be dynamically allocated to the resource in an advance manner that takes meanest execution time. More parameters are considered for performance comparison viz. flow time, average utilization and processing cost. Simulation results acknowledge the preferable achievements of the proposed scheduling schemes on the comparison of another state of art in literature. The experimental assessments and obtained results show that DTSAR is preferable than other considered heuristics in terms of TAT and other QoS parameters.

具有预先预留资源的动态任务调度，可最大程度地减少计算网格的周转时间

异构环境的一个至关重要的必要条件是在应用程序之间高效地调度资源，以优化执行时间，从而为用户提供良好的服务。该系统仅在按时提供资源并确保顺利执行任务时才有效。本文介绍了一种具有资源预先预留（DTSAR）的动态任务调度，以优化周转时间（TAT）。将以预先执行的方式将任务动态分配给资源，该方式花费了最长时间。考虑更多参数用于性能比较。流动时间，平均利用率和加工成本。仿真结果表明，与文献中另一种现有技术的比较相比，所提出的调度方案具有更好的性能。
