IBM General Parallel File System

IBM General Parallel File System

The General Parallel File System (GPFS) is a high-performance shared-disk clustered file system developed by IBM. It is used by many of the world's largest commercial companies, as well as some of the supercomputers on the Top 500 List. For example, GPFS is the filesystem of the ASC Purple Supercomputer which is composed of more than 12,000 processors and has 2 petabytes of total disk storage spanning more than 11,000 disks.

In common with typical cluster filesystems, GPFS provides concurrent high-speed file access to applications executing on multiple nodes of clusters. It can be used with AIX 5L clusters, Linux clusters, on Microsoft Windows Server, or a heterogeneous cluster of AIX, Linux and Windows nodes. In addition to providing filesystem storage capabilities, GPFS provides tools for management and administration of the GPFS cluster and allows for shared access to file systems from remote GPFS clusters.

GPFS has been available on IBM's AIX since 1998, on Linux since 2001 and on Microsoft Windows Server since 2008, and is offered as part of the IBM System Cluster 1350. The most recent release of GPFS 3.5 offers Active File Management to enable asynchronous access and control of local and remote files, thus allowing for global file collaboration.

Famous quotes containing the words general, parallel, file and/or system:

    At that,
    his small size,
    keen eyes,
    serviceable beak
    and general truculence
    assure his survival—
    William Carlos Williams (1883–1963)

    There is a parallel between the twos and the tens. Tens are trying to test their abilities again, sizing up and experimenting to discover how to fit in. They don’t mean everything they do and say. They are just testing. . . . Take a good deal of your daughter’s behavior with a grain of salt. Try to handle the really outrageous as matter-of-factly as you would a mistake in grammar or spelling.
    Stella Chess (20th century)

    I have been a soreheaded occupant of a file drawer labeled “Science Fiction” ... and I would like out, particularly since so many serious critics regularly mistake the drawer for a urinal.
    Kurt Vonnegut, Jr. (b. 1922)

    Short of a wholesale reform of college athletics—a complete breakdown of the whole system that is now focused on money and power—the women’s programs are just as doomed as the men’s are to move further and further away from the academic mission of their colleges.... We have to decide if that’s the kind of success for women’s sports that we want.
    Christine H. B. Grant, U.S. university athletic director. As quoted in the Chronicle of Higher Education, p. A42 (May 12, 1993)
