摘要
为提高基于云服务的智能家居数据接入系统的可靠性和稳定性,针对其上线之前的性能测试,提出在具有MPI环境的廉价PC机群上,实现大规模家庭网关程序模拟的编程模型ITM-MPI。对智能家居数据接入系统以及真实的应用场景进行认识和了解,指出其性能测试的重要性和难点;在此基础上,分析与其进行数据交互的家庭网关程序功能特点,结合MPI的集群特点,在较低硬件成本的基础上,仿真出大批量家庭网关程序对云端接入系统的性能进行测试。测试结果表明,该模型能够使单台PC机在性能健康的状态下实现百万级家庭网关程序的模拟,为大规模数据接入系统的性能测试提供了一种解决方案。
To improve the reliability and stability of the smart-home data access system based on cloud services？ in view of the performance test before its launch, as using cheap PC cluster with the MPI environment, ITM-MPI programming model for rea-lizing large-scale residential gateway program simulation was presented. By knowing and understanding the smart-home data ac-cess system and the real application scenario, the importance and difficulty of the performance test were pointed out. On this ba-sis？ through analyzing the function and the characteristics of the home gateway program with the data interaction, and combining with the characteristics of MPI cluster, on the basis of the lower hardware cost, a large quantity of family gateway programs were simulated to test the performance of the cloud access system. Testing results show that the model enables a single PC in the healthy state to realize the simulation of millions of family gateway program, providing a solution for the performance testing of the large-scale data access system.
