Statistics: Software on turretarch

Software supported at CHPC is often user/project driven. Software packages that we have purchased and supported in the past include:

  • BMDP
  • GAUSS
  • LISREL
  • PRELIS
  • SUDAAN

Statistics: Access
  • CHPC Unix Account Application Form
  • Our main Statistics server is a Linux machine named turretarch.chpc.utah.edu
  • Most software Executables reside in a common directory so you need not add them to your personal PATH variable. For specifics, go to the software name (listed above).
  • For users coming in from a UNIX box, use the following commands (or something similar) to set your environment to enable window display capability on your UNIX machine. Here is an example:
    • For csh or tcsh
      setenv DISPLAY myhost.mydom.utah.edu:0.0
      sas &
  • For users coming in from a Windows box who wish to use SAS, you will need to use an Xwindows environment emulator (e.g., Hummingbird). Please see OSL.utah.edu or your department for license availability.

Brief Linux Command Help

Useful commands:

  • man (cd, ftp, ssh, or any command for more info. "man" stands for manual)
  • scp <filename> <userid>@stats.chpc.utah.edu:<filename>
  • ssh stats.chpc.utah.edu
  • ls (see man for ls switch -als also; pipe to more by typing ls -als | more (press space bar to page down or down arrow key)
  • setenv DISPLAY hostname:0.0 (for csh/tcsh)
  • xterm (command shell supports tcsh)
  • c++ (c++ compiler - found in /usr/local/bin along with all the other compilers)
  • gcc (c compiler)
  • pwd (current directory path)
  • cd ("cd /" moves to root directory; "cd .." moves to previous directory, "cd" moves to your home directory, "cd /directory" moves you to /directory)
  • mkdir (creates directory)
  • rm (removes files and directories - man rm for info on switch -rf)
  • cp (copies files - cp file1 file2)
  • more filename (displays text or contents of the file. See man for cat also.)
  • emacs filename (text editor for files. xemacs is also available. See setenv below.)
  • mv (moves files - mv file1 file2)
  • ps (lists processes - try switch -aef.)
  • .cshrc (file found in user home directory; editable for adding paths, etc.)
  • echo $path (shows current paths in .cshrc file)
  • chmod (changes file permissions)
  • ln -s /directorystructure shortcut-name (creates a shortcut to a directory from your home directory)
  • scp filename username@yourcomputer.where-ever.com:/directorystructure/file (copies files to stats in a secure environment)

Using Windows on your desktop machine, you can ONLY access SAS (under Linux OS) by using an X-Windows client such as hummingbird (available through OSL) that allows SAS to open its many windows on your screen.
