Title: Large Files, Small Writes and pNFS Speaker: Dean Hildebrand, Ph.D. Candidate, University of Michigan Location: Building 980, Room 95 (Sandia NM) Brief Abstract: Numerous workload characterization studies have highlighted the prevalence of small and sequential data requests in scientific applications. Parallel file systems excel at large data transfers, often at the expense of small I/O performance. pNFS is an emerging NFSv4 extension that provides operating system and hardware independent high performance data access to parallel file systems. In this talk, I will discuss how pNFS can improve the overall write performance of parallel file systems by utilizing both the parallel file system’s I/O protocol for large write requests and the NFSv4 protocol for small write requests.
