The Sprite network operating system uses large main-memory disk block caches to achieve high performance in its file system. It provides non-write-through file caching on both client and server machines. A simple cache consistency mechanism permits files to be shared by multiple clients without

Sprite is a new operating system for networked uniprocessor and multiprocessor workstations with large physical memories. It implements a set of kernel calls much like those of 4.3 BSD UNIX, with extensions to allow processes on the same workstation to share memory and to allow processes to migrate

This paper reports on the effectiveness of the caching strategy used in the Sprite network file system based on data taken over several weeks of day-to-day usage by a variety of users. Measurements include cache consistency activity, long term I/O traffic rates, long term cache hit rates

crash recovery mechanisms have been implemented for use with network file systems, but most are too complex to fit easily into the NFS design. Spritely NFS now uses a simple recovery protocol that requires almost no client-side support and guarantees consistent behavior even if the network

recovery mechanisms have been implemented for use with network file systems, but most of these are too complex to fit easily into the NFS design. I propose a simple recovery protocol that requires almost no client-side support, and guarantees consistent behavior even if the network is partitioned

mapping interface and provides an overview of the support for these functions in other operating systems. Details of the Sprite virtual memory system and the changes to support shared memory and file mapping are given. Performance measurements show that in this implementation, mapped files have comparable

Flash-based solid-state drives have revolutionized stor-age with their high performance. Their sophisticated in-ternal mechanisms have led to a plethora of research on how to optimize applications, file systems, and internal SSD designs. Due to the closed nature of commercial de-vices though, most
