Lustre (file system) - Wikipedia, the free encyclopedia Lustre is a Free Software distributed file system, generally used for large scale cluster computing. The project aims to provide a file system to cope with clusters of tens of thousands of nodes with petabytes of storage capacity, without compromising on speed or security, and is available under the GNU GPL. Many of the fastest supercomputers in the world are clusters using the Lustre file system for storage, such as systems at ORNL, PNNL, LLNL and LANL. en.wikipedia.org /wiki/Lustre_(file_system)   (472 words)

Lustre File System Concepts   (Site not responding. Last check: 2007-10-31) At the root of Lustre is the concept of Object Storage. Lustre's model is that requests and reply packets consist of a small command or response packet and that associated with a request can be a collection of bulk data buffers that will be transferred as part of the request handling. This protocol is transaction-based and journaled; in other words, it is possible to restore the state of the file system to any previously captured epoch. home.comcast.net /~kkonsult/LustreFileSystemConcepts.html   (604 words)

NCSA Data Resources The advantages of using a parallel file system in a cluster environment are numerous. LUSTRE also known as the Linux Cluster File System, is a open source distributed file system. Changing to the appropriate scratch file system while running a job is the first step in improving I/O. For parallel applications, the goal is to have many nodes concurrently performing I/O operations. www.ncsa.uiuc.edu /UserInfo/Data/filesystems/index.html   (1667 words)

Fishing - Wikipedia, the free encyclopedia Indigenous Australians were, prior to European colonisation, most populous in Australia's better-watered areas such as the Murray-Darling river system of the south-east. The purpose of these canals was the encouragement and catching of eels, a fish of short coastal rivers (as opposed to rivers of the Murray-Darling system). There are several organizations devoted to improving the methods of collecting, handling, transporting, exporting and farming of wild and domesticated live food fish, as well as freshwater and marine tropical fish destined for aquaria. en.wikipedia.org /wiki/Fishing   (5872 words)

LRZ: Background Storage and its Handling This variable is set to the most appropriate file system for each available platform (e.g., to the XFS scratch file system on the Altix). High water mark deletion means: when the filling of the file system exceeds some limit between 80% and 90%, files will be deleted starting with the oldest and largest files until a filling of between 60% and 75% is reached. As you can access these file systems from any node in the cluster they are particularly useful for storing large files which won't fit into your AFS home directory. www.lrz-muenchen.de /services/compute/linux-cluster/files/files.html   (1617 words)

Clustered storage technologies catch on - Network World As file sizes and data sets grow into the terabyte and petabyte range, users are looking for a method for storing, accessing and sharing the files among different hosts. By clustering systems and sharing applications and data, tasks can be performed much more quickly than they could on individual machines because data doesn't need to be copied or replicated from one file system to another. In the Lustre File System, Panasas and Permabit implementations, individual servers are connected to storage by a metadata server or device, which categorizes each bit of data so it can be found easily. www.networkworld.com /news/2004/0322specialfocus.html   (966 words)

HP adds Lustre to cluster offerings - Robert McMillan, IDG News Service First developed in 2001, the Lustre file system is used by a growing number of supercomputers to let thousands of machines quickly share files. HP's Scalable File System would include software that simplified the installation and management of Lustre, freeing up engineering time that would otherwise be spent learning the software, he said. Because file system configuration couldn have a great effect on a supercomputing cluster's performance, assigning the right ratio of disk drives to file servers and clients using the Lustre file system was very important, Studham said. www.hp.com.au /enewsletter/perspective/04aug/news/pnews_item4.asp   (508 words)
