1. Banners

Banners are short announcements or pointers to more detailed information in one of the other online resources. They are displayed each time you log on to the system. If you need to access the banner message directly, it is located in /etc/motd (motd stands for message of the day).

Both motd and entries in /usr/news are available on the web at the URL below:

http://www.ncsa.uiuc.edu/UserInfo/Resources/Hardware/News/

2. news

The news command lists a number of changes affecting the system that are either too long to place on the banner message or are not recent enough to merit continued display. You are notified of new items when you log on. The news command does not automatically scroll through news items, so you may want to pipe the output of news through a standard paging program, such as more or less.

You can create a C shell alias for paging through news items. Add the following line to your .cshrc file:

alias yourcommand 'news | more'
where yourcommand is the word you want to use to display news. For example, if you add:
alias readnews 'news | more'
in your .cshrc file, enter readnews at the system prompt to display the contents of the new or unread news files.

News files can also be accessed in the /usr/news directory. Entries are also available on the Web at the URL below:

http://www.ncsa.uiuc.edu/UserInfo/Resources/Hardware/News/

3. man pages

The standard UNIX utility man is available on most NCSA systems. The -k option enables a keyword search and can be used to obtain the names of available manual pages. For example, to find fft routines, enter:
% man -k fft
Most system software and libraries have man pages.

You may want to add /usr/software-version /man to your MANPATH to get the man page for a certain compiler or library version instead of the default (where software represents the software or library name and version represents the version number). Add that path to the beginning of your MANPATH list so the newest version of the man page is found instead of the default version. To add it to your current MANPATH in C shell, use the following command: % setenv MANPATH /usr/software-version/man:$MANPATH

4. Frequently Asked Questions (FAQ)

Online FAQs are generally available for each NCSA high-performance system. Access the FAQ for your allocated system from the following URL:

http://www.ncsa.uiuc.edu/UserInfo/Resources/Hardware/

5. Early Release Documentation

When available, documentation (including release notes and bug updates) for beta software is in the /usr/software-version/doc directory, where software represents the software name and version represents the early release version of the software.

System release notes are located in /usr/doc/relnotes.

6. Online System Information

System information is available via the following commands

  • On the SGI: hinv
  • On the Exemplar: sysinfo

See the man pages for options and syntax.

7. Online Documentation

System-specific online documentation is available on each HPCC system. Access to the information requires the X Window System.

7.1 SGI InSight

The IRIS InSight Viewer from SGI is an X Window System-based online information retrieval system available on the SGI CRAY Origin2000 systems. This viewer provides an easy-to-use interface that lets you search and browse through online information distributed by Silicon Graphics.

Enter the following on the interactive machine modi4:

% setenv DISPLAY your_workstation_address:0.0

and enter the following command on your local workstation:

% xhost +modi4.ncsa.uiuc.edu

Then access the InSight program by entering:

% insight

The SGI manuals in InSight are also available on the Web at: http://techpubs.sgi.com/library.

7.2 HP Pinpoint

HP's Pinpoint is a new X Window System-based online information system available on the Exemplar SPP-2000 system. The viewer is an easy-to-use interface to the many HP-Convex documents available.

To use Pinpoint, set the value of $DISPLAY to your X Window System display (you may need to use the "xhost" command to allow display from the Exemplar) and enter:

% /usr/local/bin/pinpoint

8. Purchasing Documentation

8.1 NCSA

NCSA no longer sells documentation. Users should view documents on the Web and use their browser for printing as needed. Where possible, information is also made available in PostScript format.

Web files are developed with both online viewing and printing in mind. Information is provided as much as possible using a single file per topic to facilitate printing. To make online reading easier, a table of contents with in-document links is provided with each file.

8.2 Silicon Graphics Incorporated

SGI offers a large number of user documentation volumes that can help you take advantage of their hardware and software. NCSA does not distribute SGI documentation.

A list of available SGI documentation can be found in the Documentation Catalog in InSight. To order documentation from SGI, call SGI Direct at 1-800-800-7441 from anywhere in the U.S. or Canada. Outside of these areas, contact a sales office or distributor.

8.3 Hewlett Packard

HP-Convex offers documentation on their HPCC systems. Call 214-497-4000 for information on the available documents.
