  holidays but the new Australian mirror takes up a lot of that.

WHERE IS IT?
~~~~~~~~~~~~
At the HENSA (Higher Education National Software Archive) UNIX
archive.  The HENSA UNIX archive is accessible via the World Wide Web
(WWW), ftp, gopher, email and interactively.  For details, see below.


HOW DO I FIND WHAT I WANT?
~~~~~~~~~~~~~~~~~~~~~~~~~~
The files are all located in /pub/parallel and each directory contains a
short Index file of the contents.

If you want to check what has changed in between USENET postings, look
at the /pub/parallel/Changes file which contains the new files added.

There is also a full text index available of all the files in
/pub/parallel/info/FullIndex.ascii but be warned - it is very large
(over 680K).  Compressed and gzipped versions are in the same
directory.

For those UNIX dweebs, there are output files of ls-lR (1.0M) in
/pub/parallel/info/ls-lR along with compressed and gzipped versions
too.


HOW DO I CONTACT IT?
~~~~~~~~~~~~~~~~~~~~

There are several ways to access the files which are described below
- use the WWW, gopher, log in to the archive to browse files and
retrieve them by email or transfer files by FTP over the Internet / JIPS.


WWW Access
~~~~~~~~~~

If you have NCSA Mosaic, Netscape Mosaic, Lynx or another World Wide Web
browser, you can connect to the WWW server via:

	<URL:http://www.hensa.ac.uk/parallel/>

OR if you want reference me in your WWW tree, please use the following bit
of HTML:

<A HREF="http://www.hensa.ac.uk/parallel/">Parallel Computing Archive</A>.


Transferring files by FTP from JIPS/the Internet
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
	site: unix.hensa.ac.uk
	directory: /pub/parallel
        login: anonymous
        password: <your email address>

Use the 'get' command to transfer a file from the remote machine to
the local one.  When transferring a binary file it is important to
give the command 'binary' before initiating the transfer.  For more
details of the 'ftp' command, see the manual page by typing 'man ftp'.


Browsing and transferring by gopher
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
From the Root Minnesota Gopher gopher, select the following entries:

	8.  Other Gopher and Information Servers/
	5.  Europe/
	38. United Kingdom/
	19. HENSA unix (National software archive, University of Kent), (UK)/
	6.  Parallel Archive/

OR go straight to the gopher server at unix.hensa.ac.uk.

	unix% gopher -p 1/.archive/parallel unix.hensa.ac.uk
OR
	<URL:gopher://unix.hensa.ac.uk/11/.archive/parallel>
	(but why not use the WWW interface?)

[All the numbers are very likely to change]

The short descriptions are abbreviated to fit on an 80 column display
but the long ones can always be found under 'General Information.' (the
Index files).  Updates to the gopher tree follow a little behind the
regular updates.


Transferring files by Email
~~~~~~~~~~~~~~~~~~~~~~~~~~
To obtain a specific file email a message to

      ftpmail@unix.hensa.ac.uk

containing the single line

      help

for full instructions.


Logging in from the Internet or SuperJANET
------------------------------------------
	telnet unix.hensa.ac.uk

Once connected, use the login name 'archive' and your email address to
enter. You will then be placed inside the fbr restricted shell. Use the
help command for up to date details of what commands are available.


DONATIONS
~~~~~~~~~
Donations are very welcome.  We do not allow uploading of files directly
but if you have something you want to donate, please contact me.
