  • /tmp and /bigtmp
  • /longtmp
  • HSM
  • Other ITC supported Storage Options

25
Home Directory Service
  • http//www.itc.virginia.edu/unixsys/homedir
  • Graduate students get 100Mb by default, faculty
    125 MB quotas may be increased on request by
    e-mailing accounts_at_virginia.edu
  • Backed-up multiple times per day using Snapshot
    facility
  • http//www.itc.virginia.edu/unixsys/homedir/snapsh
    ot.html
  • Default file-system on blue.unix, Unixlab and SP2
    system
  • The home directory service can be mapped to your
    PC or Mac so you can access your files directly
    from your office or from home!
  • http//www.itc.virginia.edu/unixsys/homedir/hdlo
    gin95.html
  • http//www.itc.virignia.edu/unixsys/homdir/hdlog
    inmac.html

26
/tmp and /bigtmp
  • http//www.itc.virginia.edu/research/filestora
    ge
  • Used for short time data storage time limit of
    24 hours for files before they are deleted.
  • Can be accessed from blue.unix, SP2 and Unixlab.
  • No quota but /bigtmp but the disk is only 2GB.

27
/longtmp
  • http//www.itc.virginia.edu/research/filestorage.h
    tml
  • Two week limit on files in longtmp although in
    general users get longer.
  • longtmp has a total space of 14GB.
  • Users request their required space by sending an
    e-mail to res-consult.
  • longtmp can be accessed from blue.unix, Unixlab
    and SP2.
  • longtmp can also be mapped to your PC.
  • http//www.itc.virginia.edu/research/hsm.htmlmaps

28
HSM-Hierarchical Storage Management System
  • Large Tape system with a hard disk cache
  • To use a file from the tape system it is
    necessary to insure that the file is moved to the
    disk cache
  • cat file gt /dev/null

29
HSM
  • http//www.itc.virginia.edu/research/hsm.html
  • Large Tape library multiple Terabytes of space.
  • Should be used to archive files that are not used
    regularly.
  • Although it is a tape-system, files are accessed
    in exactly the same way as any other disk based
    file-system .
  • HSM can be mapped to your PC for direct access.
  • http//www.itc.virginia.edu/research/hsm.htmlmaps
  • Multiple copies of files are kept for data
    integrity.

30
HSM-Requesting Space
  • Request space by e-mailing
  • res-consult_at_virginia.edu
  • Post-grads usually have their space allocated
    within their supervisors directory space.
  • Initial allocations are for 5GB with up to 20GB
    or more upon on request.

31
Other ITC supported Storage Options
  • Departmental file-systems can be exported to ITC
    machines users can then access their
    directories on their departmental machines
    directly from ITC computers.
  • ACHS can provide up to 8 GB of temporary data
    storage (2 weeks).
  • ITC Unix Systems
  • http//www.itc.virginia.edu/unixsys
  • Departments can also buy additional disk wedges
    the cost is 63 for a 250MB wedge per year.

  • We distribute over 20 statistical, mathematical,
    scientific visualization and other academic
    software packages for use at U.Va. (most are
    available for free).
  • https//www.web.virginia.edu/rescomp/ldb/swdb.asp
  • And much, much more please contact us, if we
    can't help we'll try to find someone who can.

Summary
  • We provide broad range of computing support and
    services. We are here to help you get your
    research done.
  • Next talk is Wednesday, February 20 at Noon here
    on The Matlab C/C Compiler Suite 2.1
  • This talk will provide an overview of the Matlab
    C/C Compiler Suite, which includes the MATLAB
    Compiler, the MATLAB C/C Math Library, and the
    MATLAB C/C Graphics Library. These components
    allow you to convert many MATLAB applications
    that contain math, GUIs, and graphics to
    stand-alone C/C code for faster execution, and
    application distribution. Further information on
    the Matlab Compiler Suite can be found at the
    following URL
  • http//www.mathworks.com/mason/tag/proxy.html
    ?dataid560fileid1690
