摘要
Xtrem Web可以汇集联网主机的空闲CPU资源来进行高性能计算,但主机CPU负载是时变的、复杂的和非线性的,具有高度的不确定性。结合ON/OFF模型的思路,提出一个主机CPU的可用性模拟方法,对主机CPU在每日各时刻的可用性进行模拟。实验结果表明,该方法具有较高的模拟精度。
XtremWeb gathers online idle CPU resources to carry out high-performance computing. However, the host CPU load is time-varying, complex, and non-linear with a high degree of uncertainty. ON/OFF model was introduced to put forward a simulation method for the availability of host CPU for its precise simulation of the process. Experimental results show that the method has higher simulation accuracy.
