As applications scale to new levels and migrate into cloud environments, there has been a significant departure from the exclusive reliance on the POSIX file I/O interface. However in doing so, application often discover a lack of services, forcing …
Traditionally storage has not been part of a programming model's semantics and is added only as an I/O library interface. As a result, programming models, languages, and storage systems are limited in the optimizations they can perform for I/O …
As applications scale to new levels and migrate into cloud environments, there has been a significant departure from the exclusive reliance on the POSIX file I/O interface. However in doing so, application often discover a lack of services, forcing …
Solid-state drives are becoming increasingly popular in enterprise storage systems, playing the role of large caches and permanent storage. Although SSDs provide faster random access than hard-drives, their performance under read/write workloads is …
The emergence of high-performance open-source storage systems is allowing application and middleware developers to consider non-standard storage system interfaces. In contrast to the practice of virtually always designing for file-like byte-stream …
Until recently most scientific applications produced data that is saved, analyzed and visualized at later time. In recent years, with the large increase in the amount of data and computational power available there is demand for applications to …
The emergence of high-performance open-source storage systems is allowing application and middleware developers to consider non-standard storage system interfaces. In contrast to the common practice of translating all I/O access onto the POSIX file …
Exascale supercomputers will have the potential for billion-way parallelism. While physical implementations of these systems are currently not available, HPC system designers can develop models of exascale systems to evaluate system design points. …
The Hadoop Distributed File System (HDFS) has a single metadata server that sets a hard limit on its maximum size. Ceph, a high-performance distributed file system under development since 2005 and now supported in Linux, bypasses the scaling limits …
