POSIX 接口不太适合为高端应用程序提供良好的性能。 POSIX I/O 接口需要扩展，以便在并行文件系统上运行的高并发 HPC 应用程序能够良好运行。本文介绍了集群上广泛使用的并行文件系统 (PVFS) 上 POSIX I/O 接口子集的参考实现的基本原理、设计和评估。一组微基准的实验结果证实，POSIX 接口的扩展极大地提高了可扩展性和性能。
The POSIX interface does not lend itself well to enabling good performance for high-end applications. Extensions are needed in the POSIX I/O interface so that high-concurrency HPC applications running on top of parallel file systems perform well. This paper presents the rationale, design, and evaluation of a reference implementation of a subset of the POSIX I/O interfaces on a widely used parallel file system (PVFS) on clusters. Experimental results on a set of micro-benchmarks confirm that the extensions to the POSIX interface greatly improve scalability and performance.
