XSEDE提供的HPC资源为研究人员提供了开展科学研究的独特机会。截至2013年,XSEDE由16个具有不同架构设计和功能的系统组成。硬件异构性和软件多样性使得有效利用这样的计算资源联盟非常具有挑战性。例如,用户在构建和运行应用程序时经常面临无数的可能性:编译器、数值库和运行时参数。在本文中,我们报告了使用两个XSEDE系统(Kraken和Gordon)上可用的不同编译器和数值库构建的几个流行科学应用程序的性能数据,并建议了编译应用程序以获得最佳性能的最佳方法。通过比较,我们从应用的角度验证了上述XSEDE系统之间的SU转换因子。
HPC resources provided by XSEDE give researchers unique opportunities to carry out scientific studies. As of 2013 XSEDE consists of 16 systems with varied architectural designs and capabilities. The hardware heterogeneity and software diversity make efficient utilization of such a federation of computing resources very challenging. For example, users are constantly faced with a myriad of possibilities to build and run an application: compilers, numerical libraries, and runtime parameters. In this paper we report performance data of several popular scientific applications built with different compilers and numerical libraries available on two XSEDE systems: Kraken and Gordon, and suggest the best way to compile applications for optimal performance. By comparison, we validate SU conversion factors between the aforementioned XSEDE systems from application's viewpoint.
