    Stata Log Files

    Details

    Log files keep a record of the command statements you enter and Stata's output. Specifying a filename saves the log to a file; saving as a log format rather than the default SMCL format will allow you to open the log in other applications (such as Microsoft Word or Notepad).

    A log file can be opened or started in two ways:

    Stata Data Files

    Details

    Stata can read the following filetypes:

    .dta - a data file in Stata format
    .txt - data in ASCII (text) format
    .raw - data in ASCII (text) format
    .xls - a data file in Excel format

    Different command statements are used to load data sets in different file formats. Most commonly you'll issue the use command to read Stata formatted data sets.

    Hardware Resources for Researchers

    Details

    Researchers at Dartmouth have access to High Performance Computing (HPC) resources including the Discovery cluster and Linux computer servers with licensed mathematics and statistical applications, compliers, debuggers and scientific libraries. Research Computing provides data storage for researchers and Linux support for private research workstations.

    Differences Between AFS and Native UNIX/Macintosh/Windows File Systems

    Details

    Most users will only notice small differences between AFS home directories and standard UNIX home directories, but there are differences some users will encounter on a daily basis. The table below highlights the major differences users are likely to notice when using AFS.

    Integrating AFS Authentication with Local Login

    Details

    The explicit klog step can be omitted if the system is configured to obtain AFS credentials as part of the standard login process. To do this, the usernames on your local system must match the usernames defined in the AFS user databases.

    Changing Your AFS Password

    Details

    You can change your password from any system that has the Kerberos tools or AFS client installed. The easiest way for Linux users is to login to Polaris, Andes or Discovery and use the command rcpasswd. Here is an example of what that will look like.

    legacy accounts:

    NOTE: Input is NOT VISIBLE
    Changing password for 'username' in cell 'northstar.dartmouth.edu'.
    Old password:                       (nothing echoes)
    New password (RETURN to abort):     (nothing echoes)

    or, recent accounts in RSTOR Kerberos system:

    Connect To A Linux Server

    Details

    How Do I Connect from My Windows Machine to a Linux Server?

    You can connect from a Windows computer to a Linux machine in one of two ways, depending on what you want to accomplish, what services are available on the remote host, and whether you require graphics to be displayed. You can use a text-only connection (also referred to as a command line, or terminal interface) or a graphical (X-windows) connection.

    Compilers on 64-bit and 32-bit Research Computing Systems

    Details

    A 64-bit computer can handle more computations, memory, and I/O than a 32-bit computer. To take advantage of this additional power, software must be built with 64-bit compilers. The 64-bit computer can run 32-bit applications, but running them in 32-bit mode doesn't use all the expanded capabilities of the 64-bit computer. However, software built to use a 64-bit computer cannot run on a 32-bit computer.



    Debuggers on Research Computing's Linux systems

    Details

    In general, you should use either the debugger that is supplied with each type of compiler or a general purpose debugger like TotalView. The table below provides the compilers and their associated debuggers for the compilers installed on Research Computing Linux computers.

    How Do I Store Research Data Or Files?

    Details

    Where Do I Store My Data?

    Researchers have access to RStor for data storage. See RStor - Central Data Storage for Researchers.

    How Do I Restore My Research Data or Files from RStor?

    To restore your data or files, email [email protected].
