| 英文摘要 | To meet the increasing requirements of computing in server-side, more co-processors, such as GPU and MIC, become the new components of server-side. However, traditional serve-side software, such as Web server software etc, could not make full use of the performance of these co-processors. In order to exploit the performance of MIC co-processors and improve the quality of service of a single Web server node, this paper proposed a new dynamic request processing model, which aimed at CPU and MIC co-processors heterogeneous systems. This model could schedule some dynamic requests to MIC co-processors and handle these dynamic requests in parallel with CPU on basis of event driven model and thread pool model. Furthermore, this model could also keep balance between CPU and MIC co-processors by adopting adaptive load balance algorithm. Simulation experiments show that this model is superior to the existing Web server software model in mean response time, throughput and 99% response time. |
