传统上，网格和高性能计算（HPC）存储研究社区之间很少有互动。网格研究通常侧重于优化高延迟广域网的数据访问，而HPC研究则侧重于优化本地高性能存储系统的数据访问。最近的软件和硬件趋势正在模糊网格和HPC之间的区别。在本文中，我们调查使用的I/O转发-一个完善的技术，在领导级的HPC机器-在网格环境中。我们发现，引发引入的I/O转发HPC系统的问题也适用于当代网格计算环境。我们提出了我们的I/O转发基础设施的网格计算环境的设计。此外，我们还讨论了我们的基础设施为网格提供的优势，例如简化异构计算环境中的应用程序数据管理以及对多个应用程序I/O接口的支持。
Traditionally, little interaction has taken place between the Grid and high-performance computing (HPC) storage research communities. Grid research often focused on optimizing data accesses for high-latency, wide-area networks, while HPC research focused on optimizing data accesses for local, high-performance storage systems. Recent software and hardware trends are blurring the distinction between Grids and HPC. In this paper, we investigate the use of I/O forwarding -- a well established technique in leadership-class HPC machines-- in a Grid context. We show that the problems that triggered the introduction of I/O forwarding for HPC systems also apply to contemporary Grid computing environments. We present the design of our I/O forwarding infrastructure for Grid computing environments. Moreover, we discuss the advantages our infrastructure provides for Grids, such as simplified application data management in heterogeneous computing environments and support for multiple application I/O interfaces.
