  (Re)appearances by the occam and transputer areas plus PVM interest
  too.


WHERE IS IT?
~~~~~~~~~~~
At the HENSA Unix (Higher Education National Software Archive) archive,
funded by the JISC.  The HENSA Unix archive is accessible via the WWW, ftp,
gopher as well as an interactive browsing facility called fbr.

The parallel archive is provided with help and funding from SEL-HPC (London
and South East centre for High Performance Computing) project and the EU
COMETT project supporting occam and Transputer training.



HOW DO I FIND WHAT I WANT?
~~~~~~~~~~~~~~~~~~~~~~~~~~

The files are all located in /pub/parallel for ftp, email and
interactive access and in the root directory for gopher.  Each
directory contains several index files of the contents: AFA-INDEX
(the source), Index and index.html. 

If you want to check what has changed in between these postings, look at
/pub/parallel/Changes or <URL:http:/www.hensa.ac.uk/parallel/www/changes.html>
file which contains the new files added.  Files older than that are in
/pub/parallel/info/Changes, indexed by year/month.

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
530K).  Compressed and gzipped versions are in the same directory.

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

In addition, there are several WAIS indices of the archive, which can be
accessed from the WWW home page, see below.  The WAIS support will be
dropped soon to be replaced by another, not yet decided, searching method.


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	(or 129.12.43.16 on SuperJANET)
        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 at the Root Minnesota Gopher gopher, select the following entries:

	8.  Other Gopher and Information Servers/

	5.  Europe/

	45. United Kingdom/

	22. HENSA unix (National software archive, University of Kent), (UK)/

	7.  Parallel Archive/

OR add the following to your .gopherrc

	Name=Parallel Archive
	Type=1
	Port=70
	Path=1/.archive/parallel
	Host=nutmeg.ukc.ac.uk.

OR Use <URL:gopher://unix.hensa.ac.uk/11/.archive/parallel>
   [But if you can use this, the WWW interface is much better]

Then browse the archive.  [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

      archive@unix.hensa.ac.uk

containing the single line

      send path-of-file

or 'help' for more information. Getting /pub/parallel/README, or
/pub/parallel/FullIndex.ascii would be a good start.

**NOTE INTERFACE WILL CHANGE SOON**

Logging in from the Internet or SuperJANET
------------------------------------------

	telnet unix.hensa.ac.uk	(or 129.12.43.16)

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.


COMING SOON
~~~~~~~~~~~
WWW occam and transputer teaching materials.
New searching method. (Via Harvest system?)
Acronyms area.


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.
