Exploring Data Compression in Distributed File Systems
The ever-growing imbalance between computation and I/O is one of the fundamental challenges for current petascale and future exascale systems. As these large systems become more compute heavy by design, it is becoming harder to support dataintensive applications with adequate performance. To narrow the gap between computation and I/O, parallel and distributed file systems have been introduced. ...
متن کاملDistributed File Systems
Need of storing a huge amount of data has grown over the past years. Whether data are of multimedia types (e.g. images, audio, or video) or are produced by scientific computation, they should be stored for future reuse or for sharing among users. Users also need their data as quick as possible. Data files can be stored on a local file system or on a distributed file system. Local file system pr...
متن کاملDistributed File Systems
File servers can be stateful or stateless. Stateful servers are keeping state information about their clients, whereas the stateless don't. Stateful servers have the big disadvantage that if the server crashes all the state information is lost. They are not very scalable due to the space overhead. Their big advantages are: shorter messages can be used and better performance. Stateless server ar...
متن کاملcoordination of protective schemes in distribution and subtransmission systems including distributed generation
نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
Appointed File Prefetching for Distributed File Systems
One of key issues in the design of distributed file systems is how to reduce the latency when accessing remote files, with the solutions including cache replacement and file-prefetching technologies. In this paper, we propose a novel method called appointed file prefetching, in which the main idea is to enable the user or system administrator to specify how to perform file prefetching. We defin...
