【摘要】：云计算环境下数据规模较大,当前资源配置方法依据优先级、按照顺序对资源进行配置,具有资源利用率低、配置效率低、能耗高等弊端。为此,提出一种新的云计算环境下浮点和整数同时多线程资源配置方法,分析了计算操作和访存操作的并发性,给出云计算环境下和每片外访存load操作相应的发射执行指令数的定义,得出在相同时间段内IPM值越大,计算型与访存型操作同时执行的机会越大,资源配置性能越高的结论。依据该结论,通过IPM实现云计算环境下浮点和整数同时多线程资源配置,将较多的资源分配至IPM值较大的浮点或整数线程中,将较少的资源分配至IPM值较小的浮点或整数线程中,使得云计算环境下的共享资源得到最佳配置。利用实验测试所提方法的实际应用性能。实验结果表明,所提方法资源利用率高、能耗损失低、资源配置效率高,整体资源配置性能很高。
[Abstract]:In the cloud computing environment, the data scale is large, the current resource allocation method allocates resources according to priority, according to the order of resources, which has the disadvantages of low resource utilization, low allocation efficiency, high energy consumption and so on. In this paper, a new resource allocation method of floating-point and integer multi-thread in cloud computing environment is proposed, and the concurrency of computing operation and memory access operation is analyzed. The definition of the number of transmit and execute instructions corresponding to each load operation in the cloud computing environment is given. It is concluded that the larger the IPM value in the same time period, the greater the chance of both computational and memory access operations to execute simultaneously, and the higher the performance of resource allocation. According to this conclusion, the floating-point and integer multi-thread resource configuration in cloud computing environment is realized by IPM, and more resources are allocated to floating-point or integer thread with higher IPM value. Fewer resources are allocated to floating-point or integer thread with lower IPM value, which makes the shared resources in cloud computing environment best configured. The practical application performance of the proposed method is tested by experiment. The experimental results show that the proposed method has the advantages of high resource utilization, low energy loss, high resource allocation efficiency and high overall resource allocation performance.
