摘要

我们提出了在并行计算环境下科学应用的用户可控I/O操作，并通过一些综合访问模式探讨了它们的影响。这些操作允许用户以最少数量的I/O请求共同呈现多个访问模式。这使系统能够聚合并行磁盘的带宽，优化磁盘磁头运动，然后提高I/O性能。

User-controllable parallel I/O for scientific applications

We propose user controllable I/O operations for scientific applications in parallel computing environments and explore the effects of them with some synthetic access patterns. The operations allow users to present numerous access patterns collectively with a minimum number of I/O requests. This enables systems to aggregate bandwidth of parallel disks, optimize disk head movements, and then increase I/O performance.
