This paper presents a study of the performance of federated queries implemented in a system that simulates the architecture proposed for the Scalable Architecture for Federated Translational Inquiries Network (SAFTINet). Performance tests were conducted using both physical hardware and virtual machines within the test laboratory of the Center for High Performance Computing at the University of Utah. Tests were performed on SAFTINet networks ranging from 4 to 32 nodes with databases containing synthetic data for several million patients. The results show that the caGrid FQE (Federated Query Engine) is capable and suitable for comparative effectiveness research (CER) federated queries given its nearly linear scalability as partner nodes increase in number. The results presented here are also important for the specification of the hardware required to run a CER grid.
本文介绍了一项对在模拟联邦转化查询网络可扩展架构(SAFTINet)所提议架构的系统中实现的联邦查询性能的研究。性能测试是在犹他大学高性能计算中心的测试实验室中使用物理硬件和虚拟机进行的。测试针对包含数百万患者合成数据的数据库,在4到32个节点的SAFTINet网络上进行。结果表明,鉴于随着伙伴节点数量增加其具有近乎线性的可扩展性,caGrid联邦查询引擎(Federated Query Engine)能够且适用于比较效果研究(CER)联邦查询。这里呈现的结果对于运行CER网格所需硬件的规格说明也很重要。
