Compilers

Vendor compilers are available on all systems for C, C++ and FORTRAN. The Gnu C and C++ compilers are also available on the Suns. A complete description of each compiler and its options is available as a Unix manual page accessible with the man command:

%man cc

Mathematics Computation Packages

There are several software packages available to do numerical computation, modeling, graphing and plotting. To use a package with a graphical interface on a remote system, it is necessary to tell the remote system to display it on the local display with the following command issued on the remote system:
%setenv DISPLAY local:0.0

The local system must also be told to allow the remote system to use its display with the following command issued on the local system:
%xhost remote
Package Availability Startup Command
Maple All systems. Text only: %maple
Graphics: %xmaple
Mathematica euler only Text only: %math
Graphics: %mathematica
Matlab All systems. Text and graphical versions: %matlab
The DISPLAY setting determines
which version will be run.
Macsyma All Sun 4.1.4 systems. Version 4.19: %macsyma
Version 4.20: %macsyma420
Requires the following additional
environment variable setting:
%setenv LMGR_HOST crunch






Statistics Computation Packages

There are two software packages available to do statistical analysis. To use a package with a graphical interface on a remote system, it is necessary to tell the remote system to display it on the local display with the following command issued on the remote system:
%setenv DISPLAY local:0.0

The local system must also be told to allow the remote system to use its display with the following command issued on the local system:
%xhost remote



Package Availability Startup Command
Splus All Sun systems. %splus
Gauss glacier only %gauss





Typesetting

The text formatting programs TeX and LaTeX are available on all systems. The newest version is LaTeX2e and is accessible as the command latex. Version 2.09 is also available on the Sun 4.1.4 systems as the command oldlatex. For more inforamtion check on the online documentation for TeX and LaTeX.

Files produced by LaTeX are in DVI (DeVice Independent) format. These files can be viewed with xdvi which is also available on all systems. These files cannot be sent directly to a printer. They must first be converted to Postscript via the dvips command which will send the output directly to the printer or with the -o option will save to a file. The resulting file can be sent to a printer using the lpr command and/or viewed with ghostview or gs.

Editors

There are four editors available on all Unix systems to create and alter plain text files:
emacs
A man page is available as well as a tutorial within the program. To start, simply enter emacs at the Unix prompt. This editor has a graphical user interface as well as a text-based interface that will run on any text terminal or window. If the DISPLAY environment variable is set then emacs will attempt to run the graphical user interface. To run the text only interface, use the -nw option to emacs:
    %emacs -nw
or unset the DISPLAY variable:
    %unsetenv DISPLAY
The first page presents the basic commands necessary to get started including the tutorial and help commands.
xemacs
This is a graphical user interface version of emacs that provides pull-down menus for command as well as positioning within a document via the mouse. This version will be run automatically if the DISPLAY environment when the emacs command is entered at the Unix prompt. A man page is available as well as a tutorial within the program. The first page presents the basic commands necessary to get started including the tutorial and help commands.
pico
This editor is a text-based interface that will run on any text terminal or window. To start, simply enter pico at the Unix prompt. A list of available commands will appear at the bottom of the screen, including a "Get Help" command.
vi
This editor is a text-based interface that will run on any text terminal or window. To start, simply enter vi at the Unix prompt. To exit, hit the escape key and type ZZ. There is no help available within vi although a man page is available.
