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 925K).  Compressed and gzipped versions are in the same
directory.

For those UNIX dweebs, there are output files of ls-lR (1.5M) 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
~~~~~~~~~~

Connect your WWW browser program (e.g. NCSA Mosaic, Netscape
Navigator, Lynx, ...) 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/">Internet 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
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Starting from the Root Minnesota Gopher gopher, follow the menu entries:

	Other Gopher and Information Servers
	Europe
	United Kingdom
	HENSA unix (National software archive, University of Kent), (UK)
	Internet Parallel Computing 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?)

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.
