提出并实现了一种对网格应用所需资源进行预留管理的系统,研究了多种粒度的资源预留,可满足不同应用的资源需求.用户根据应用选择合适的资源预留粒度,以减少资源的浪费,提高资源利用率.为了适应网格应用资源需求的动态变化,该系统允许在运行时动态地调整资源预留的持续时间或预留资源量.性能测试表明:随着干扰程序的规模的增加,在没有资源预留的情况下,干扰程序规模最大时Linpack测试值是没有干扰程序时的0.39%,在使用CPU预留时对应的百分比为103.38%.
Proposed and implemented a system for reservation management of resources required for grid application and studied resource reservation with multiple granularities to meet the resource requirements of different applications.Users select the appropriate resource reservation granularity according to the application, Reduce resource waste and improve resource utilization.In order to adapt to the dynamic changes of grid application resource requirements, the system allows to dynamically adjust the duration of resource reservation or reserve resources at runtime.Performance tests show that with the interference program . Without resource reservation, the Linpack test value is 0.39% of the time without interrupting the program at the largest interfering program size, and 103.38% when using the CPU reservation.
