    Parallel file systems are often characterized by a layered architecture that decouples metadata management from I/O operations, allowing file systems to facilitate fast concurrent access to file contents. However, metadata intensive workloads are still likely to bottleneck at the file system control plane due to namespace synchronization, which taxes application performance through lock contention...

    HPC platforms are capable of generating huge amounts of metadata about different entities including jobs, users, and files. Simple metadata, which describe the attributes of these entities (e.g., file size, name, and permissions mode), has been well recorded and used in current systems. However, only a limited amount of rich metadata, which records not only the attributes of entities but also rela... View full abstract»

    With the emergence of multi-core and multi-socket non-uniform memory access (NUMA) platforms in recent years, new software challenges have arisen to use them efficiently. In the field of high performance computing (HPC), parallel programming has always been the key factor to improve applications performance. However, the implications of parallel architectures in the system software has been overlo... View full abstract»

  • Alleviating I/O Interference via Caching and Rate-Controlled Prefetching without Degrading Migration Performance

    Publication Year: 2014, Page(s):19 - 24

    The process of migrating a virtual machine and its virtual storage can greatly degrade the performance of other guests and applications running on the same host, including the migrating machine itself. Through experimental evaluation, we investigate the I/O performance degradation imposed by storage migration on co-located machines. We examine naive approaches for mitigating this interference by a... View full abstract»

    In this paper, we propose a Versatile Searchable File System, VSFS, which builds POSIX-compatible namespace using a novel Namespace-based File Query Language (NFQL). This enables analytics applications to utilize VSFS high-performance file-search service without changing their data model. VSFS versatile file-indexing mechanism is designed to offer great flexibility for applications to control indi... View full abstract»

    The study of the I/O performance of a parallel application can be facilitated by the use of an I/O kernel -- a program that generates the same I/O calls as the original application, but can be executed much faster. Such I/O kernels are especially important when the programs under study are proprietary or classified, and only available in binary form.In this paper, we show how to create automatical...

    The performance gap between processor and storage device has continuously increased during the past few decades. The gap is further exacerbated recently because applications are becoming more data-intensive in both industry and academia. Traditional storage devices, such as hard disk drives (HDD), fail to keep up with the paces of this growth. A known solution is to use solid state drives (SSD) as... View full abstract»

    Evaluating I/O performance of an application across different systems is a daunting task because it requires preparation of the software dependencies and required input data. Feign aims to be an extensible trace replay solution for parallel applications that supports arbitrary software and library layers. The tool abstracts and streamlines the replay process while allowing plug-ins to provide, man... View full abstract»
